+Add the armv5e architecture to binutils
+
+Binutils has a comment that indicates it is supposed to match gcc for all of
+the support "-march=" settings, but it was lacking the armv5e setting.  This
+was a simple way to add it, as thumb instructions shouldn't be generated by
+the compiler anyway.
+
+Upstream-Status: Denied
+Upstream maintainer indicated that we should not be using armv5e, even though
+it is a legal archicture defined by our gcc.

+Subject: [PATCH 1/1] Silence uninitialized warning on ehdr_start_save
+
+Older GCC, like 4.1/4.2, will issue an uninitialized warning on
+ehdr_start_save.  This patch silences by using
+
+struct bfd_link_hash_entry ehdr_start_save = ehdr_start_save;
+
+	* emultempl/elf32.em (gld${EMULATION_NAME}_before_allocation):
+	Silence uninitialized warning on ehdr_start_save with older
+	GCC.
+
+Upstream-Status: Backport

+# Problem Statement:
+  Eliminate sign and zero extensions in PPC generated code
+
+# Owned by:
+  Edmar Wienskoski and John Russo
+
+# Action:
+  a) Eliminate sign and zero extensions in PPC generated code
+     A new module is introduced 'extelim.c' and a new RTL pass is introduced.
+     The '-f[no-]extelim' flag controls this pass and is enabled at -O2 and above.
+     The algorithm is based on the paper "Effective Sign Extension Elimination", Kawahito, et. al.
+     More details on implementation in the extelim.c module.
+
+  b) Combine clrldi and rldicr into a single rldic instruction. The particular difficulty in the
+     presented test case is that the clrldi reaches the rldicr instruction via a branch from the
+     bottom of a loop. This make the combination inappropriate for the combine phase
+     (reaches across basic blocks). The solution is to duplicate the clrldi at a reaching point at
+     rldicr and let the extension elimination eliminate the now redundant original clrldi.  The
+     instruction selector now sees the adjacent clrldi,rldicr (int rtl form) and selects the rldic
+     instruction.
+
+     This is only effective for 64-bit targets that have rldic instructions.
+     The test case rldic-1.c and tests that rldic is generated for the test case.
+
+  c) This patch also contains extension elimination fix for ENGR00225973 (segmentation fault at -O3).
+
+  d) Append patch to fix spec2k perlbmk issue when using -flto -funroll-loops
+
+  e) Append patch to select active 'prev_insn', else we end up with consecutive extensions 
+    (one inserted, one previously there) for return instructions. 
+
+  f) Updated changes to match with GCC v4.9.x source base.
+
+  g) Update vect-reduc-pattern-2b-big-array.c test case to prevent signed overflow.
+
+  h) The main entry point of extension elimination algorithm was returning void.
+     With v4.9.x source base, this file is compiled by C++ compiler which optimizes this code.
+     Update changes to work with v4.9.x source base.
+     Remove unused variables from 'init_flags_vector'.
+
+  i) spec2k.gap relies on signed arithmetic overflow being well-defined.
+     Disable extension elimination for '-fwrapv, -ftrapv, -fno-strict-overflow'.
+
+  j) Fix 20040709-2.c [-Os] and 20111227-1.c [-O2,-O3,-Os].
+     "operation_extends_to_upper_bits_size" had one of the conditional check reversed
+     which eliminated a required sign extension instruction.
+
+  k) Update gcc.dg/sms-1.c and gcc.dg/sms-6.c test cases so that Swing Modulo Scheduling happens
+
+  l) Added target macro header file to fix ICE in windows build with GCC v4.9.x
+
+  m) Add test case from coriant team which got fixed by (j).

++
++GENERAL APPROACH:
++Consider a machine whose native register size is 64-bits
++
++0          3132         63
++|-----------||-----------|
++
++where bit 63 is the LSB and bit 0 is the MSB of a long int
++and bit 63 is the LSB and bit 32 is the MSB of an int.
++
++Sign and zero extension are inserted to RTL to preserve the
++operation's semantics when the operands used are not the 
++native register size since normally the machine only performs
++the operation using a native register size. In practice, many
++of the inserted extensions are not necessary.
++
++First, the extension may simply be redundant. That is, the 
++same operation is performed on the same operands. The redundant
++extensions can be eliminated.
++
++Secondly, if the extended portion of the register (the "upper" bits)
++are not essential to the calculations performed on the output of the
++extension, then the extension is not necessary. For example, given
++int (32-bit) inputs and outputs:
++
++c = a + b
++d = sxt(c)
++e = d + 1; 
++
++The "upper" bits of d (bit 0-31) do not affect the calculation
++of e. It doesn't matter what the "upper" bits of d are, the int result
++e is the same regardless of the sxt instruction.
++
++Thirdly, the extensions may not be necessary if the operands are
++already extended and the operation preserves the extended bits.
++
++a = mem[&b] ; sign extending load
++c = a + 1
++d = sxt(c)
++
++Here, a is generated by a sign extending load, the operation
++does nothing to invalidate the extension to c, thus the extension
++on c to d is not necessary.
++
++In each case, the redundant extension must be replaced by a copy,
++with the copy to be optimized out in later phases.
++
++The three cases described above form the general idea behind the
++algorithms implemented here to eliminate redundant and unneccessary
++extensions. 
++
++Sign extensions do not have to be preserved for overflow conditions
++since signed overflow behavior is not defined in C. For example,
++take a 16-bit variable in a 32-bit register. It is ok
++for 0x0000_7fff to overflow to 0x0000_8000 and not 0xffff_8000.
++This implies that it is not necessary to preserve the sign
++extension.
++
++Unsigned overflow extension need to be preserved because 
++unsigned overflow is modulo. For example, a 16-bit unsigned 
++overflow of 0x0000_FFFF must be 0x0000_0000 in a 32-bit register, 
++not 0x0001_0000. In order to remove the unsigned zero extension,
++we would need to range check the variable to be sure it doesn't
++overflow.  
++
++RTL ANALYSIS:
++I looked at the RTL representation after RTL generation (.expand) and
++after the first forward propagation (.fwprop1). Since RTL is not compact
++when printing out, I reduced the .fwprop1 RTL to this pseudocode:
++
++(note: sxt,zxt mean double word length, 64-bit, extension).
++
++(1)     r198 = m[r113+ #112]     ; load a[0]
++(2)     r174 = sxt(r198)
++(3)     r199 = m[r113+ #116]     ; load a[1] 
++(4)     r186 = sxt(r199)
++(5)     r181 = r113 + #120       ; load &a[2]
++(6)     r180 = 2                 ; i = 2
++(7)     L1:
++(8)     r200 = r174 + r186       ; t1 = a[i-1] + a[i-2]
++(9)     r174 = sxt(r200)
++(10)    m[r181] = r200           ; a[i] = t1
++(11)    r201 = r200 + r186       ; t2 = t1 + a[i-1]
++(12)    r186 = sxt(r201)
++(13)    m[r181+4] = r201         ; a[i+1] = t2
++(14)    r202 = r180 + 2          ; i += 2
++(14.1)  r180 = sxt(r202)     
++(15)    r203 = 100 - r202        ; used to calc loop remainder
++(16)    r185 = zxt(r203)         ; used to calc loop remainder
++(17)    r181 = r181 + 8          ; address induction var
++(18)    ccr204 = cmp(r202,#98)   ; set CC
++(19)    BNE ccr204,L1            ; branch 
++
++In the pseudo-code, you see several sign extension candidates: (2),(4),
++(9), (12), (14.1), (16).  
++
++ALGORITHM:
++To eliminate the extra sign ext you have to look at (1) the definitions
++of the source of the sign extensions and/or (2) look at the uses of the target
++of the sign extensions. In either case, if doing a global elimination
++pass, you'll need def-use chain information. 
++
++The algorithms are recursive. Using the use/def and def/use chains
++we attempt to find ultimately whether the extension is relevant
++or not. 
++
++
++Example 1.
++Extensions (2) and (4) are not put in the candidate list because
++they are combined into a load/ext pair that is ultimately generated
++as sign extending loads.
++
++Take the sign extension at (9), r174 = sxt(r200).
++Def analysis shows that r200 is defined by 2 registers, thus no
++further def analysis recursion can occur.
++Use analysis. Find all the uses of r174. There is 1 use at (8) r200 = r174 + r186. 
++The extension does not affect the add operation results. Continuing, we look at
++the uses of r200 to see if the results of operations on r200 need the sign extended bits.
++We see 2 uses of r200 at (10) and (11). (10) is a 32-bit store of r200,
++so the sign extended bits are irrelevant. (11), however, is an unknown,
++so we must look that the uses of this result, r201. A similar sequence
++occurs for r201 when it defines r186. Looking at the uses of r186 at 
++(8) and (11), we have already visited those statements so they have
++been covered already. So it appears that the sxt to r174 at (9) ultimately
++dead-ends to a store instruction that doesn't case about the sign extended
++bits. The sxt at (9) can be removed.
++
++The remaining extensions are processed similarly.

++Iteration 4: pre-ZERO_EXTEND version, duplicates sign_extend at uses
++Iteration 5: begin supporting ZERO_EXTEND, crashes on Coremark.
++Iteration 6: revert to 4, support SI:HI sign_extensions.
++Iteration 7: Add support for zero extend. This version deletes
++ "inserted" duplicate extensions when redundant and propagates
++ the copied value. This propagate fails in other_tests/test2.sh.
++ I am reverting back to replacing the "inserted" extension to a copy.
++ Copy propagation should always be able to eliminate this copy.
++ Coremark was stable, however.
++Iteration 8: Revert to change extensions to copy, regardless of whether
++ the extension was duplicated or not. 
++ Refactor setting of dest,src in analyze_ext_use, analyze_ext_def, now
++ handled with a single function.
++Iteration 9: 
++ Inserted redundant extensions at function return points.
++ Sorted the order that extensions are processed by loop depth.
++ Additional cases in upper_bits_do_not_affect_dest
++Iteration 10:
++ Fixes for test failures. A major problem was uncovered where
++ the "visited" flag was not properly cleared. This meant that
++ each time a new extension was processed, it appeared that some
++ extensions were visited already and there were not. The result
++ was false removals. This fix significantly affects the benchmark.
++ Another change was to comment out the duplicate_exts_at_uses. This
++ seemed to have little effect now that the visited flag issue is
++ fixed. 
++Iteration 11:
++ Cleanup warnings during build.
++Iteration 12:
++ QImode support started.
++Iteration 13:
++ Redesign and refactor analyze_ext_use, analyze_ext_def
++Iteration 14:
++ Continue redesign and refactor of analyze_ext_use, analyze_ext_def
++ Debugging paper_example.c
++Iteration 15:
++ cond_c fix
++Iteration 16: (not tested)
++ Refactor check_compare code 
++ Refactor action decision in PARALLEL 
++ Allow pass-thru on insns that are marked for replace copy 
++ instead of stopping recursion if we see a marked insn.
++ Examining lshiftrt.c program (signed and unsigned).
++Iteration 17: 
++ Refactor mostly complete. Passed all local testing including
++ nas and perfect. Best coremark results so far.
++Iteration 18:
++ Oops. analyze_ext_def was disabled. Enabling it improves
++ Coremark. Passed coremark, perfect.
++Iteration 19:
++ Local tests are passing. Tested with glibc.
++ Added statistics.
++ Fixed elimination from CALL output in operand_is_extended.
++  This impacted Coremark went from 6300 to 6170. But is necessary.
++ More safety for used regs in analyze_ext_def.
++ More safety for the types of extensions.
++Iteration 20:
++ Fixes for various tests.
++Iteration 21:
++ pr43017 -funroll_loops fix.
++Iteration 22:
++ Fixes for AND immediate in operand_is_extended.
++ Cosmetic cleanup.
++Iteration 23:
++ Fixes for consumer-2,spec2k,spec2k6. Handle 
++ SUBREG_PROMOTED_VAR_P flags on operands whose
++ dependent extension has been eliminated.
++Iteration 24:
++ Fixed problem in native build during bootstrapping.
++ Extelim was considering debug_insns and should have
++ ignored them. This resulted in a compare fail between
++ stage2 and stage3.
++Iteration 25:
++ - Post-release 4.6.1 development
++ - Full duplication of extensions at uses turned on.
++ - Recursion into original extension no longer kills optimization (analyze_ext_def only)
++ - Allow some duplication into the same block if it enables insn selection
++ - Allow CCmode and CCUNSmode into mode_supported_p
++Iteration 26:
++ - Solve ICEs due to null df-ref.
++Iteration 27:
++ - Fixed issue with duplication of extension at a self-assign.
++ - Some fixes for copying flags during duplication
++ - Some fixes for counting register uses.
++Iteration 28:
++ - Fixed issue with duplication of extension when use has multiple
++   reaching definitions.
++Iteration 29:
++ - Release candidate for Q42011 release iteration.
++Iteration 30:
++ - Turn off extension duplication - minimally effective
++Iteration 31:
++ - Turn on extension duplication for specific case to allow
++   'rldic' insn generation.
++Iteration 32:
++ - Fix issue with spec2k6 soplex where zero-extends duplicated
++   even if shift is already zero-extended.

++/* Analyze the insn and determine the next course of action in the

++   There are several conditions to consider:
++
++   1. The "extended from" mode. This is an enum machine_mode value
++   that determines what is the size extended. It is derived from the
++   source of the original extension. It is the "low bits" value.
++   It is these range of bits that cannot be affected by the operation's
++   "upper bits" in order to determine whether the extend is useful or not.
++   Examples: 
++   (1) set (reg:DI Y (zero_extend:DI (subreg:QI (reg:DI X))) ==> low bits = QI
++   (2) set (reg:SI Y (sign_extend:SI (reg:HI X) ==> low bits = HI
++
++   2. The "extend to" mode. This is the size extended to in the original
++   extension. It is the "upper bits" value. The entire extended to size may 
++   be used subsequently or it may be subreg'd to a smaller or larger sizes 
++   later in the propagation.
++   For example (1) above, "upper bits" is DI, and (2) "upper bits" is SI.
++
++   3. The code, ext_code, of the original extension, either ZERO_EXTEND or SIGN_EXTEND.
++
++   4. Operation code. For an insn, the actual operation code corresponding to
++   a machine instruction. For certain codes, we know that the "low bits" of the
++   result are modified by the insn because of the values in the "upper bits" of the
++   input operand. We say the operation implicitly uses the "upper bits" to modify the
++   "low bits". For other codes, the "upper bits" do not affect the output result
++   in the "low bits". 
++
++   If the operation does implicitly use the "upper bits" to modify
++   the "low bits", it is instantly a deal killer. The original extension must be 
++   preserved. 
++
++   If the operation does not implicitly use "upper bits" to modify the "low bits",
++   then the action to take depends on the operation operand size relative to 
++   "low bits" size.
++
++   We only want to deal with codes that map to real instructions,
++   like ADD, SUB, MULT, LSHIFTRT, etc. Codes such as PARALLEL, etc. do not map to
++   instruction and must be dissected to extract the real instructions.
++
++   Furthermode, for recursion to continue, the operation and operand must define
++   an output related to the input operand (the use register). This doesn't happen
++   for operations such as "mem" where the output is indirectly related to the
++   input operand. 
++
++   5. Operation mode. The operation mode of the operation code. This sometimes impacts
++   the effect of the operation. For example MULT:SI and MULT:DI map to two different
++   machine instructions and both may have operands of SI mode. However, the MULT:SI 
++   results will be oblivious to the upper bits of the DI register whereas, SI part of
++   MULT:DI result will be affected by the upper bits of the DI register.
++
++   Several conditions determine the action to take based on the various inputs.
++
++   The truth table inputs are A, B, and C. The truth table output is the action to take. 
++
++   A. True if the used operand mode size is greater than the extended_from ("low bits") mode size.
++   B. True if the operation implicitly uses upper bits to define the low bits  
++   C. True if the operation also extends the output to upper bits size
++   D. True if the operation and input operand directly define an output operand.
++
++   Condition A. means the upper bits are in use in the operation. The extend _may_ be needed, 
++   all things being equal, so the action would be to continue recursion to the use of the
++   defined operand, i.e. return CONTINUE_RECURSION.
++
++   Condition B. means the "low bits" are modified by the extended portion of the register
++   by virtue of the operation. For example, logical shift right, where the extended
++   portion is shifted into the "low bits". Another example, multiply, where the machine
++   uses the extended portion implicitly to calculate the results, some of which are 
++   reflected in the "low bits" of the result. The extension is definitely needed in these 
++   cases for this use, so return LOWBITS_AFFECTED. Recursion is stopped and analysis of 
++   this extension is halted.
++
++   Condition C. means the operation and it's operands perform the same extension as
++   the originating extension. The operation must extend to the same size _or higher_ of
++   the original extension. In this case, the original extension is truly redundant and
++   we return LOWBITS_NOT_AFFECTED for this use.
++
++   Condtion D. means the operation and operand directly define an output operand. For most
++   arithmetic and unary operations this is true. For mem and other internal operations,
++   e.g. USE, this is false.
++
++      Condition                      Action                 Comments
++    ==================================================================

+# Problem Statement:
+  Eliminate sign and zero extensions in PPC generated code based on
+  Value Range Information.
+
+# Owned by:
+  Rohit
+
+# Referred from patch by:
+  Kugan Vivekanandarajah
+
+# Action:
+  * Backport r213749 and r213750 from trunk to remove
+    redundant sign/zero extensions during RTL expansion.
+  * Fix ENGR00340415 and add test case.
+  * Add code to eliminate sign/zero extension for ternary operation.

++/* This is a GIMPLE pass over basic block which coverts the stmts:
++        
++        a = b +/- c1;
++	c = a * c2;
++        
++   to:
++   
++        a = b * c2;
++        c = a +/- c1 * c2;
++
++   in effect expanding the multiplication across addition/substraction.
++
++   Motivating example:
++   Consider the following simple integer array access:
++   
++        a[i] = c;
++        a[i + 1] = c;
++
++   The following GIMPLE equivalent will be generated:
++
++        off_1 = i * 4;
++        a_i = a + off_1;
++	*a_i = c;
++
++	off_1 = i + 1;
++	off_2 = off_1 * 4;
++	a_i1 = a + off_2;
++	*a_i1 = c;
++
++   Notice that a_i1 could simply be a_i + 4. But the calcuation of i+1
++   is preventing CSE to perform. This pass will essentially convert the
++   second expr into:
++
++        off_1 = i * 4;
++        off_2 = off_1 + 4;
++        a_i1 = a + off_2;
++        ....
++
++   Thus allowing the previous index i calculation to be reuse. off_1 + 4
++   would also be combined into a_i if offset addressing mode is available.
++   This also have side effect of avoiding redundant sign extension on
++   i+1 for LP64 model where native integer size is different from pointer size.
++
++   The algorithm iterates through all the basic blocks looking for
++   the above pattern. Care is taken to make sure off_1 only
++   has the single use otherwise the transformation cannot be perform.

+
+Add /sw/include and /opt/include based on the original
+zecke-no-host-includes.patch patch.  The original patch checked for
+/usr/include, /sw/include and /opt/include and then triggered a failure and
+aborted.
+
+Instead, we add the two missing items to the current scan.  If the user
+wants this to be a failure, they can add "-Werror=poison-system-directories".

++GCC also provides a family of builtins on PowerPC to explicitly use
++the @code{isel} instruction.  While GCC can and does generate
++@code{isel} instructions normally, the builtins enable you to
++explicitly force generation of these instructions.  The builtins are
++only available when compiling for processors that support the
++@code{isel} instruction; they compile to a code sequence of
++@code{cmpw} followed by @code{isel}.

+Subject: [PATCH 18/35] gcc-4.3.3: SYSROOT_CFLAGS_FOR_TARGET
+
+Before committing, I noticed that PR/32161 was marked as a dup of PR/32009, but my previous patch did not fix it.
+
+This alternative patch is better because it lets you just use CFLAGS_FOR_TARGET to set the compilation flags for libgcc. Since bootstrapped target libraries are never compiled with the native compiler, it makes little sense to use different flags for stage1 and later stages. And it also makes little sense to use a different variable than CFLAGS_FOR_TARGET.
+
+Other changes I had to do include:
+
+- moving the creation of default CFLAGS_FOR_TARGET from Makefile.am to configure.ac, because otherwise the BOOT_CFLAGS are substituted into CFLAGS_FOR_TARGET (which is "-O2 -g $(CFLAGS)") via $(CFLAGS). It is also cleaner this way though.
+
+- passing the right CFLAGS to configure scripts as exported environment variables
+
+I also stopped passing LIBCFLAGS to configure scripts since they are unused in the whole src tree. And I updated the documentation as H-P reminded me to do.
+
+Bootstrapped/regtested i686-pc-linux-gnu, will commit to 4.4 shortly. Ok for 4.3?

+Subject: [PATCH 19/35] 64-bit multilib hack.
+
+GCC has internal multilib handling code but it assumes a very specific rigid directory
+layout. The build system implementation of multilib layout is very generic and allows
+complete customisation of the library directories.
+
+This patch is a partial solution to allow any custom directories to be passed into gcc
+and handled correctly. It forces gcc to use the base_libdir (which is the current
+directory, "."). We need to do this for each multilib that is configured as we don't
+know which compiler options may be being passed into the compiler. Since we have a compiler
+per mulitlib at this point that isn't an issue.
+
+The one problem is the target compiler is only going to work for the default multlilib at
+this point. Ideally we'd figure out which multilibs were being enabled with which paths
+and be able to patch these entries with a complete set of correct paths but this we
+don't have such code at this point. This is something the target gcc recipe should do
+and override these platform defaults in its build config.

+Subject: [PATCH 20/35] optional libstdc
+
+gcc-runtime builds libstdc++ separately from gcc-cross-*. Its configure tests using g++
+will not run correctly since by default the linker will try to link against libstdc++
+which shouldn't exist yet. We need an option to disable -lstdc++
+option whilst leaving -lc, -lgcc and other automatic library dependencies added by gcc
+driver. This patch adds such an option which only disables the -lstdc++.
+
+A "standard" gcc build uses xgcc and hence avoids this. We should ask upstream how to
+do this officially, the likely answer is don't build libstdc++ separately.

+# Problem Statement
+ This patch implements option -fbypass-load-on-store
+
+ A load on store collision causes the load to to be replayed if the store has not completed.
+ Under -fbypass-load-on-store, GCC will attempt to avoid a load on store collision by trying
+ to space the load away from the store by scheduling upto 14 instructions in between, to
+ prevent the load from executing too early.
+
+# Owned by:
+  Russo John
+
+# Action:
+
+ * -fbypass-load-on-store is enabled under -fschedule-insns
+ * Cores supported: e5500, e6500, e500mc
+ * Ref: Load-on-Store Collision Avoidance by Software Stall of Load. James Yang. May 18, 2010
+
+ Rev2:
+ * Scheduler is switched off at -O0. Re-work the test case.

+Subject: [PATCH 21/35] gcc: disable MASK_RELAX_PIC_CALLS bit
+
+The new feature added after 4.3.3
+"http://www.pubbs.net/200909/gcc/94048-patch-add-support-for-rmipsjalr.html"
+will cause cc1plus eat up all the system memory when build webkit-gtk.
+The function mips_get_pic_call_symbol keeps on recursively calling itself.
+Disable this feature to walk aside the bug.

+For altivec targets, 32 bits, the spec2k-gap bmk does not build.  The
+reason is that at some point the vectorizer creates an CONST_VECTOR
+rtl, where the elements are SYMBOL_REFs.
+
+Gcc ICE on simplify_immed_subreg, where it checks that CONST_VECTORS
+can be only made of CONST_INT, CONST_DOUBLE, or CONST_FIXED.
+
+I really don't understand what that function does, but since the
+vectorizer will bailout later anyway, I think it is safe to treat
+SYMBOL_REFs as CONST_INT. (NOT for FSF submission, as I really don't
+have a clue)
+
+This problem does not exists on gcc-4.5
+
+This problem does not exists on 64 bits, since there is no altivec
+type that can support 64bit elements.

+
+Use the defaults.h in ${B} instead of ${S}, and t-oe in ${B}, so that
+the source can be shared between gcc-cross-initial,
+gcc-cross-intermediate, gcc-cross, gcc-runtime, and also the sdk build.

+
+While compiling gcc-crosssdk-initial-x86_64 on some host, there is
+occasionally failure that test the existance of default.h doesn't
+work, the reason is tm_include_list='** defaults.h' rather than
+tm_include_list='** ./defaults.h'
+
+So we add the test condition for this situation.

+# Problem Statement:
+  In Altivec targets (e.g. e6500), DWARF vector register indices for DW_OP_regx
+  locations are not in range. According to "64-bit PowerPC ELF Application
+  Binary Interface Supplement 1.9", DWARF Register Number Mapping section, the
+  expected range for vector registers is:
+                 Vector Registers 0-31 1124-1155 vr0-vr31.
+
+  However, the compiler generates indices in the 77-108 range that overlap with
+  other defined mappings.
+
+# Reported by:
+  Doan Vu Van
+
+# Owned by:
+  Rohit
+
+# Action:
+  While mapping gcc register numbers to DWARF2 register numbers,
+  we digress a bit from the standard ABI.
+  http://gcc.gnu.org/ml/gcc-patches/2012-11/msg02136.html
+
+  The above change is handled by GDB, but CodeWarrior PowerPC debugger
+  stricity follows the ABI especially while mapping the vector registers.
+
+  We have provided an compiler option, '-mmap_dwarf_vecreg' so that the user can
+  generate the dwarf register indexes for vector registers as per standard.

+# Action:

+     by default.
+  2. If the loop count of the initialization loop is known at compile time, 
+     generate sequence of store instructions for 'memset' calls based on the

+  7. Set upper bound limit (256/512) for generation of sequence of store
+     instructions to prevent stack overflow due to code bloat.
+  8. To override the default no. of bytes to be cleared values, use the
+     target flag '-mmax_block_clear='.
+  9. To disable this change and get default GCC behavior use the flag

+Subject: [PATCH 27/35] cpp: honor sysroot.
+
+Currently, if the gcc toolchain is relocated and installed from sstate, then you try and compile
+preprocessed source (.i or .ii files), the compiler will try and access the builtin sysroot location
+rather than the --sysroot option specified on the commandline. If access to that directory is
+permission denied (unreadable), gcc will error.
+
+This happens when ccache is in use due to the fact it uses preprocessed source files.
+
+The fix below adds %I to the cpp-output spec macro so the default substitutions for -iprefix,
+-isystem, -isysroot happen and the correct sysroot is used.

+Subject: [PATCH 30/35] gcc: Fix argument list too long error.
+
+There would be an "Argument list too long" error when the
+build directory is longer than 200, this is caused by:
+
+headers=`echo $(PLUGIN_HEADERS) | tr ' ' '\012' | sort -u`
+
+The PLUGIN_HEADERS is too long before sort, so the "echo" can't handle
+it, use the $(sort list) of GNU make which can handle the too long list
+would fix the problem, the header would be short enough after sorted.
+The "tr ' ' '\012'" was used for translating the space to "\n", the
+$(sort list) doesn't need this.

+Subject: [PATCH 31/35] Disable sdt.
+
+We don't list dtrace in DEPENDS so we shouldn't be depending on this header.
+It may or may not exist from preivous builds though. To be determinstic, disable
+sdt.h usage always. This avoids build failures if the header is removed after configure
+but before libgcc is compiled for example.

+
+Disable sdt for libstdc++-v3.

+# Problem Statement:
+  Fix office-1.dither01 degradation with GCC v492.
+
+  Targets: e500mc & e5500 (32-bit).
+
+  There were 2 issues:
+  
+  a) lwzx and dependent cmp instruction were scheduled too close.
+  b) Loop invariant code being not moved out.
+
+# Owned by:
+  Rohit
+
+# Action:
+  a) Adjust the scheduler cost between lwzx and dependent cmp instruction
+     so that the lwzx instruction gets scheduled earlier.
+
+  b) Adjust the address cost so that the loop invariant code gets moved out.
+     Since the same cost calculation affects forward propagation, it causes
+     degradation in other benchmarks. So make this change specific to loop 
+     invariant code optimization.
+
+  c) Referenced test case is part of 'dither' benchmark code.

+Subject: [PATCH 32/35] libtool
+
+libstdc++ from gcc-runtime gets created with -rpath=/usr/lib/../lib for qemux86-64
+when running on am x86_64 build host.
+
+This patch stops this speading to libdir in the libstdc++.la file within libtool.
+Arguably, it shouldn't be passing this into libtool in the first place but
+for now this resolves the nastiest problems this causes.
+
+func_normal_abspath would resolve an empty path to `pwd` so we need
+to filter the zero case.

+Subject: [PATCH 33/35] gcc: armv4: pass fix-v4bx to linker to support EABI.
+
+The LINK_SPEC for linux gets overwritten by linux-eabi.h which
+means the value of TARGET_FIX_V4BX_SPEC gets lost and as a result
+the option is not passed to linker when chosing march=armv4
+This patch redefines this in linux-eabi.h and reinserts it
+for eabi defaulting toolchains.
+
+We might want to send it upstream.

+# Problem Statement:

+  information is not generated in .debug_frame section as required by
+  the DWARF standard.

+
+# Action:
+  * Update the header file e500mc.h to set appropriate target macros.
+  * AEABI is a proxy for Linux ABI, so these changes should not affect

+
+Note this is a *build* target (in build-x86_64-linux) so it should be using 
+the host "gcc", not x86_64-pokysdk-mingw32-gcc. Since the mingw32 headers are 
+very different, using the wrong cpp is a real problem. It is leaking into 
+configure through the CPP variable. Ultimately this leads to build failures 
+related to not being able to include a process.h file for pem-unix.c.
+
+The fix is to ensure we export a sane CPP value into the build environment when
+using build targets. We could define a CPP_FOR_BUILD value which may be the version
+which needs to be upstreamed but for now, this fix is good enough to avoid the 
+problem.

+gengtype is generated for both the build system and the target. -DGENERATOR_FILE
+was added in the patch http://gcc.gnu.org/ml/gcc-patches/2012-07/msg00273.html
+and was applied to both versions of gengtype.
+
+Unfortunately the presence of this flag triggers the build configuration (bconfig.h) 
+to be included for the target build of gengtype. Compiling gengtype with the target 
+compiler and bconfig.h can result in errors if the build and target systems are 
+dissimilar. An example case this fails is cross compiling gcc on linux for a darwin 
+target system:

+
+The obvious fix is to only include the flag on build/ targets which this patch does, however 
+this also leads to compile errors due to const_tree being undefined but used in double_int.h
+
+I added a GENERATOR_FILE2 flag to workaround those in the

+When compiling a project using -frepo, .rpo files are written alongside
+the .o file, the symbols either have O or C against them. During final linking,
+the objects can be recompiled with some of the entries tweaked/chosen by the 
+tlink.c code (visible with TLINK_VERBOSE=3), it does this by changing O -> C
+in the .rpo files.
+
+My tests showed that init_repo (cp/repo.c) was correctly calling 
+IDENTIFIER_REPO_CHOSEN against the right identifers and setting the
+chosen bit.
+
+By the time finish_repo() or emit_repo_p() were called, the pointer returned
+by get_identifier() for the symbol marked during init_repo had changed and
+the chosen bit was no longer set. This lead to linking bugs like:
+
+collect: relinking
+collect2: error: '_ZNK6sudoku5ClearINS_8SequenceEEclERS1_' was assigned to 'board.rpo', but was not defined during recompilation, or vice versa
+
+The problem is that the garbage collection is getting called before
+finish_repo() is called and ggc_protect_identifiers is set to false 
+so the identifiers are not preserved. They are recreated but the 
+chosen bits get wiped out which is why the pointer changes and the 
+chosen bit is not set.
+
+The fix is to change ggc_protect_identifiers *after* the finish_repo 
+calls are made.
+
+Reproduction is tricky since you need to trigger the garbage collector at
+just the right moment.

+Subject: [PATCH] Enable SPE & AltiVec generation on powepc*linux target
+
+When is configured with --target=powerpc-linux, the resulting GCC will 
+not be able to generate code for SPE targets (e500v1/v2).
+GCC configured with --target=powerpc-linuxspe will not be able to
+generate AltiVec instructions (for e6500).
+This patch modifies the configured file such that SPE or AltiVec code
+can be generated when gcc is configured with --target=powerpc-linux.
+The ABI and speciffic instructions can be selected through the
+"-mabi=spe or -mabi=altivec" and the "-mspe or -maltivec" parameters.

+Subject: [PATCH] gcc: fix segfault from calling free on non-malloc'd area
+
+We see the following on a 32bit gcc installed on 64 bit host:
+
+  Reading symbols from ./i586-pokymllib32-linux-gcc...done.
+  (gdb) run
+  Starting program: x86-pokymllib32-linux/lib32-gcc/4.9.0-r0/image/usr/bin/i586-pokymllib32-linux-gcc
+
+  Program received signal SIGSEGV, Segmentation fault.
+  0xf7e957e0 in free () from /lib/i386-linux-gnu/libc.so.6
+  (gdb) bt
+  #0  0xf7e957e0 in free () from /lib/i386-linux-gnu/libc.so.6
+  #1  0x0804b73c in set_multilib_dir () at gcc-4.9.0/gcc/gcc.c:7827
+  #2  main (argc=1, argv=0xffffd504) at gcc-4.9.0/gcc/gcc.c:6688
+  (gdb)
+
+The problem arises because we conditionally assign the pointer we
+eventually free, and the conditional may assign the pointer to the
+non-malloc'd internal string "." which fails when we free it here:
+
+   if (multilib_dir == NULL && multilib_os_dir != NULL
+       && strcmp (multilib_os_dir, ".") == 0)
+     {
+       free (CONST_CAST (char *, multilib_os_dir));
+       ...
+
+As suggested by Jakub, ensure the "." case is also malloc'd via
+xstrdup() and hence the pointer for the "." case can be freed.

+gcc/Makefile.in: fix parallel building failure
+
+The gcc-ar.o, gcc-nm.o, gcc-ranlib.o and errors.o included
+config.h which was a generated file. But no explicity rule
+to clarify the dependency. There was potential building
+failure while parallel make.
+
+For gcc-ar.o, gcc-nm.o and gcc-ranlib.o, they were compiled from one C
+source file gcc-ar.c, we add them to ALL_HOST_BACKEND_OBJS, so the
+'$(ALL_HOST_OBJS) : | $(generated_files)' rule could work for these
+objects.
+
+For errors.o, it is part of gengtype, and the gengtype generator program
+is special: Two versions are built. One is for the build machine, and one
+is for the host. We refered what gengtype-parse.o did (which also is part
+of gengtype).

+Disable the MULTILIB_OSDIRNAMES and other multilib options.
+
+Hard coding the MULTILIB_OSDIRNAMES with ../lib64 is causing problems on
+systems where the libdir is NOT set to /lib64.  This is allowed by the ABI, as
+long as the dynamic loader is present in /lib.
+

+Subject: [PATCH] Only allow e500 double in SPE_SIMD_REGNO_P registers.
+
+rs6000_hard_regno_nregs_internal allows SPE vectors in single
+registers satisfying SPE_SIMD_REGNO_P (i.e. register numbers 0 to
+31).  However, the corresponding test for e500 double treats all
+registers as being able to store a 64-bit value, rather than just
+those GPRs.
+
+Logically this inconsistency is wrong; in addition, it causes problems
+unwinding from signal handlers.  linux-unwind.h uses
+ARG_POINTER_REGNUM as a place to store the return address from a
+signal handler, but this logic in rs6000_hard_regno_nregs_internal
+results in that being considered an 8-byte register, resulting in
+assertion failures.
+(<https://gcc.gnu.org/ml/gcc-patches/2014-09/msg02625.html> first
+needs to be applied for unwinding to work in general on e500.)  This
+patch makes rs6000_hard_regno_nregs_internal handle the e500 double
+case consistently with SPE vectors.
+
+Tested with no regressions with cross to powerpc-linux-gnuspe (given
+the aforementioned patch applied).  Failures of signal handling
+unwinding tests such as gcc.dg/cleanup-{8,9,10,11}.c are fixed by this
+patch.
+
+	* config/rs6000/rs6000.c (rs6000_hard_regno_nregs_internal): Do
+	not allow e500 double in registers not satisyfing
+	SPE_SIMD_REGNO_P.

+Ensure target gcc headers can be included
+
+There are a few headers installed as part of the OpenEmbedded
+gcc-runtime target (omp.h, ssp/*.h). Being installed from a recipe
+built for the target architecture, these are within the target
+sysroot and not cross/nativesdk; thus they weren't able to be
+found by gcc with the existing search paths. Add support for
+picking up these headers under the sysroot supplied on the gcc

+Being able to build a nativesdk gcc is useful, particularly in cases
+where the host compiler may be of an incompatible version (or a 32
+bit compiler is needed).
+
+Sadly, building nativesdk-gcc is not straight forward. We install
+nativesdk-gcc into a relocatable location and this means that its
+library locations can change. "Normal" sysroot support doesn't help
+in this case since the values of paths like "libdir" change, not just
+base root directory of the system.
+
+In order to handle this we do two things:
+
+a) Add %r into spec file markup which can be used for injected paths
+   such as SYSTEMLIBS_DIR (see gcc_multilib_setup()).
+b) Add other paths which need relocation into a .gccrelocprefix section
+   which the relocation code will notice and adjust automatically.

+Search target sysroot gcc version specific dirs with multilib.
+
+We install the gcc libraries (such as crtbegin.p) into
+<sysroot><libdir>/<target-sys>/5.2.0/
+which is a default search path for GCC (aka multi_suffix in the 
+code below). <target-sys> is 'machine' in gcc's terminology. We use
+these directories so that multiple gcc versions could in theory 
+co-exist on target.
+
+We only want to build one gcc-cross-canadian per arch and have this work 
+for all multilibs. <target-sys> can be handled by mapping the multilib
+<target-sys> to the one used by gcc-cross-canadian, e.g. mips64-polkmllib32-linux 
+is symlinked to by mips64-poky-linux.
+
+The default gcc search path in the target sysroot for a "lib64" mutlilib is:
+
+<sysroot>/lib32/mips64-poky-linux/5.2.0/
+<sysroot>/lib32/../lib64/
+<sysroot>/usr/lib32/mips64-poky-linux/5.2.0/
+<sysroot>/usr/lib32/../lib64/
+<sysroot>/lib32/
+<sysroot>/usr/lib32/
+
+which means that the lib32 crtbegin.o will be found and the lib64 ones
+will not which leads to compiler failures.
+
+This patch injects a multilib version of that path first so the lib64
+binaries can be found first. With this change the search path becomes:
+
+<sysroot>/lib32/../lib64/mips64-poky-linux/5.2.0/
+<sysroot>/lib32/mips64-poky-linux/5.2.0/
+<sysroot>/lib32/../lib64/
+<sysroot>/usr/lib32/../lib64/mips64-poky-linux/5.2.0/
+<sysroot>/usr/lib32/mips64-poky-linux/5.2.0/

+Subject: [PATCH 19/35] 64-bit multilib hack.
+
+GCC has internal multilib handling code but it assumes a very specific rigid directory
+layout. The build system implementation of multilib layout is very generic and allows
+complete customisation of the library directories.
+
+This patch is a partial solution to allow any custom directories to be passed into gcc
+and handled correctly. It forces gcc to use the base_libdir (which is the current
+directory, "."). We need to do this for each multilib that is configured as we don't
+know which compiler options may be being passed into the compiler. Since we have a compiler
+per mulitlib at this point that isn't an issue.
+
+The one problem is the target compiler is only going to work for the default multlilib at
+this point. Ideally we'd figure out which multilibs were being enabled with which paths
+and be able to patch these entries with a complete set of correct paths but this we
+don't have such code at this point. This is something the target gcc recipe should do
+and override these platform defaults in its build config.

+From 9e0e19eac2562f73858602fe26e2044eb8b20c47 Mon Sep 17 00:00:00 2001
+From: Alexandru-Cezar Sardan <alexandru.sardan@freescale.com>
+Date: Wed, 5 Feb 2014 16:52:31 +0200
+Subject: [PATCH] Enable SPE & AltiVec generation on powepc*linux target
+
+When is configured with --target=powerpc-linux, the resulting GCC will 
+not be able to generate code for SPE targets (e500v1/v2).
+GCC configured with --target=powerpc-linuxspe will not be able to
+generate AltiVec instructions (for e6500).
+This patch modifies the configured file such that SPE or AltiVec code
+can be generated when gcc is configured with --target=powerpc-linux.
+The ABI and speciffic instructions can be selected through the
+"-mabi=spe or -mabi=altivec" and the "-mspe or -maltivec" parameters.
+
+Upstream-Status: Inappropriate [configuration]

+Fix various _FOR_BUILD and related variables
+
+When doing a FOR_BUILD thing, you have to override CFLAGS with
+CFLAGS_FOR_BUILD. And if you use C++, you also have to override
+CXXFLAGS with CXXFLAGS_FOR_BUILD.
+Without this, when building for mingw, you end up trying to use
+the mingw headers for a host build.
+
+The same goes for other variables as well, such as CPPFLAGS,
+CPP, and GMPINC.

+# Problem Statement:
+  ENGR00215432:
+  The purpose of this patch is to disable the use of dcbz in the 32-bit memset.
+  However, this does not fix the root problem because any program
+  -- not just one using eglibc's memset -- can contain dcbz instruction,
+  so it is an incomplete fix anyway.
+
+  There is support in the Linux kernel as of 2.6.33 to emulate the correct
+  behavior (though it seems nobody really knows how well the workaround works),
+  so if the program that uses libc is running on this or a later kernel it does
+  not need to check for an 8xx.
+
+  Therefore one solution is to require kernel 2.6.33 or later.

+# Problem Statement:
+  Dhrystone benchmark gave performance degradation due to
+  code alignment.
+  Target: e5500 (32 & 64-bit) 
+
+  Note: This is not a library optimization patch but a performance fix.
+
+# Owned by:
+  Rohit
+
+# Actions:
+  * Aligned loop code of strcmp library to 16 bytes.
+  * Broke down lwzu/ldu to lwz/ld+addi.
+    This combination gives good performance numbers.

+# Problem Statement:
+  Implement target specific optimized strchr for e500mc & e5500 32-bit.
+
+# Owned by:
+  Mahesh [based on existing 'asm' implementation of eglibc strchr]
+
+# Actions:
+  * For e500mc target, default glibc implementation was reading
+    two words at a time. Current implementation unrolls the loop to 
+    read sixteen words.
+
+  * For e5500 [32-bit] target, use cmpb instruction to check the occurance
+    of NULL and expected character in a string.
+
+  * Reordered the instruction to get the better performance
+
+  * Got time out error with e5500 (32-bit) target on eglibc test suite.
+    Didn't find any degradation with our performance tests.
+    So updating TIMEOUT boundary to 10.

+# Problem Statement:
+  Implement target specific optimized strcpy for e500mc,32-bit e5500,
+  64-bit e5500
+
+# Owned by:
+  Ajay [based on existing 'asm' implementation of glibc]
+
+# Actions:
+  * For e500mc and e5500 [32-bit and 64-bit] targets, there is a slight
+    improvement in the performance for aligned data.
+
+  * For e500mc and e5500 [32-bit and 64-bit] targets, there is a appreciable
+    improvement in the performance [approx. 64% in case of e500mc and 32-bit
+    e5500 and 78% in case of 64-bit e5500] for non-aligned data.
+
+  * Rev2:
+    a) e5500 64-bit: Fixed "segmentation fault" issues for strcpy with eglibc
+       v2.15 test suite for unaligned data.

++
++/* The algorithm here uses the following techniques:
++
++   1) Given a word 'x', we can test to see if it contains any 0 bytes
++      by subtracting 0x01010101, and seeing if any of the high bits of each
++      byte changed from 0 to 1.  This works because the least significant
++      0 byte must have had no incoming carry (otherwise it's not the least
++      significant), so it is 0x00 - 0x01 == 0xff.  For all other
++      byte values, either they have the high bit set initially, or when
++      1 is subtracted you get a value in the range 0x00-0x7f, none of which
++      have their high bit set.  The expression here is
++      (x + 0xfefefeff) & ~(x | 0x7f7f7f7f), which gives 0x00000000 when
++      there were no 0x00 bytes in the word.  You get 0x80 in bytes that
++      match, but possibly false 0x80 matches in the next more significant
++      byte to a true match due to carries.  For little-endian this is
++      of no consequence since the least significant match is the one
++      we're interested in, but big-endian needs method 2 to find which
++      byte matches.
++
++   2) Given a word 'x', we can test to see _which_ byte was zero by
++      calculating ~(((x & 0x7f7f7f7f) + 0x7f7f7f7f) | x | 0x7f7f7f7f).
++      This produces 0x80 in each byte that was zero, and 0x00 in all
++      the other bytes.  The '| 0x7f7f7f7f' clears the low 7 bits in each
++      byte, and the '| x' part ensures that bytes with the high bit set
++      produce 0x00.  The addition will carry into the high bit of each byte
++      iff that byte had one of its low 7 bits set.  We can then just see
++      which was the most significant bit set and divide by 8 to find how
++      many to add to the index.
++      This is from the book 'The PowerPC Compiler Writer's Guide',
++      by Steve Hoxey, Faraydon Karim, Bill Hay and Hank Warren.
++
++   We deal with strings not aligned to a word boundary by taking the
++   first word and ensuring that bytes not part of the string
++   are treated as nonzero.  To allow for memory latency, we unroll the
++   loop a few times, being careful to ensure that we do not read ahead
++   across cache line boundaries.
++
++   Questions to answer:
++   1) How long are strings passed to strlen? If they're often really long,
++   we should probably use cache management instructions and/or unroll the
++   loop more.  If they're often quite short, it might be better to use
++   fact (2) in the inner loop than have to recalculate it.
++   2) How popular are bytes with the high bit set? If they are very rare,
++   on some processors it might be useful to use the simpler expression
++   ~((x - 0x01010101) | 0x7f7f7f7f) (that is, on processors with only one
++   ALU), but this fails when any character has its high bit set.  */
++
++/* Some notes on register usage: Under the SVR4 ABI, we can use registers
++   0 and 3 through 12 (so long as we don't call any procedures) without
++   saving them.  We can also use registers 14 through 31 if we save them.
++   We can't use r1 (it's the stack pointer), r2 nor r13 because the user
++   program may expect them to hold their usual value if we get sent
++   a signal.  Integer parameters are passed in r3 through r10.
++   We can use condition registers cr0, cr1, cr5, cr6, and cr7 without saving
++   them, the others we must save.  */

++              The EGLIBC Component Configuration System
++                  Jim Blandy <jimb@codesourcery.com>
++
++Introduction
++
++The GNU C library (GLIBC) provides a broad range of functionality,
++ranging from internationalization support to transcendental
++mathematical functions.  Its website boasts that "nearly all known and
++useful functions from any other C library are available."  This
++exhaustive approach has been one of GLIBC's strengths on desktop and
++server systems, but it has also given GLIBC a large footprint, both in
++memory and on disk, making it a challenge to use in embedded systems
++with limited resources.
++
++The Embedded GNU C library (EGLIBC) is a variant of the GNU C library
++designed to work well on embedded systems.  In particular, EGLIBC's
++component configuration system allows embedded developers to build
++customized versions of the library that include only the features
++their application uses, reducing its space requirements.
++
++EGLIBC's component configuration system categorizes the library's
++functions into "option groups", and allows you to include or exclude
++option groups individually.  Some option groups depend on others;
++EGLIBC tracks these relationships, and ensures that the selected
++configuration yields a functioning library.
++
++
++Consistent and Predictable Behavior
++
++A flexible configuration system is a mixed blessing: if the options
++offered are poorly designed, it can be hard to see which choices will
++have the desired effects, and choices with obscure consequences can
++make debugging difficult.  EGLIBC's configuration follows some general
++principles to reduce these risks:
++
++- EGLIBC has a single default configuration for each target
++  architecture.
++
++- In the default configuration, all option groups are enabled, and
++  EGLIBC is upwardly API- and ABI-compatible with GLIBC.
++
++- As much as possible, configurations only affect what functions are
++  present, not how they behave.  If the system works with an option
++  group disabled, it will still work with it enabled.
++
++- As much as possible, configurations only select option groups ---
++  they do not describe characteristics of the target architecture.
++
++These rules mean that you have a simple debugging strategy available
++if you suspect that your EGLIBC configuration might be the source of a
++problem: fall back to the default configuration, re-test, and then
++disable option groups one by one, until the problem reappears.
++
++
++The Option Groups
++
++To see the current full list of implemented option groups, refer to the
++file 'option-groups.def' at the top of the source tree, or run
++'make menuconfig' from the top-level build directory.
++
++The POSIX.1-2001 specification includes a suggested partition of all
++the functions in the POSIX C API into option groups: math functions
++like 'sin' and 'cos'; networking functions like 'socket' and
++'connect'; and so on.  EGLIBC could use this partitioning as the basis
++for future option groups.
++
++
++Implementation
++
++The EGLIBC component configuration system resembles the approach used
++by the Linux kernel to select device drivers, network protocols, and
++other features.  A file named 'option-groups.config' in the top-level
++build directory contains assignments to Make variables, each of which
++enables or disables a particular option group.  If the variable's
++value is set to 'y', then the option group is enabled; if it set to
++anything else, the option group is omitted.  The file
++'option-groups.defaults', at the top of the source tree, establishes
++default values for all variables; all option groups are enabled by
++default.
++
++For example, the following 'option-groups.config' would omit locale
++data, but include mathematical functions, and everything else:
++
++   OPTION_EGLIBC_LOCALES = n
++   OPTION_EGLIBC_LIBM = y
++
++Like the Linux kernel, EGLIBC supports a similar set of '*config' make
++targets to make it easier to create 'option-groups.config', with all
++dependencies between option groups automatically satisfied.  Run
++'make help' to see the list of supported make config targets.  For
++example, 'make menuconfig' will update the current config utilising a
++menu based program.
++
++The option group names and their type (boolean, int, hex, string), help
++description, and dependencies with other option groups, are described by
++'option-groups.def' at the top of the source tree, analogous to the
++'Kconfig' files in the Linux kernel.
++
++In general, each option group variable controls whether a given set of
++object files in EGLIBC is compiled and included in the final
++libraries, or omitted from the build.
++
++Each subdirectory's Makefile categorizes its routines, libraries, and
++executables by option group.  For example, EGLIBC's 'math/Makefile'
++places the 'libm' library in the OPTION_EGLIBC_LIBM group as follows:
++
++   extra-libs-$(OPTION_EGLIBC_LIBM) := libm
++
++Finally, common code in 'Makerules' cites the value of the variable
++'extra-libs-y', selecting only those libraries that belong to enabled
++option groups to be built.
++
++
++Current Status and Future Directions
++
++The EGLIBC component configuration system described here is still
++under development.
++
++We have used the system to subset some portions of EGLIBC's

++       networking; aliases; public keys; and so on) consult the
++       '/etc/nsswitch.conf' configuration file to decide how to handle
++       queries.
++
++       With this option group disabled, EGLIBC uses a fixed list of
++       services to satisfy queries on each database, as requested by
++       configuration files specified when EGLIBC is built.  Your
++       'option-groups.config' file must set the following two
++       variables:
++
++config EGLIBC_NSSWITCH_FIXED_CONFIG
++   string "Nsswitch fixed config filename"
++   depends on !EGLIBC_NSSWITCH
++   default ""
++   help
++          Set this to the name of a file whose contents observe the
++          same syntax as an ordinary '/etc/nsswitch.conf' file.  The
++          EGLIBC build process parses this file just as EGLIBC would
++          at run time if EGLIBC_NSSWITCH were enabled, and
++          produces a C library that uses the nsswitch service
++          libraries to search for database entries as this file
++          specifies, instead of consulting '/etc/nsswitch.conf' at run
++          time.
++
++          This should be an absolute filename.  The EGLIBC build
++          process may use it from several different working
++          directories.  It may include references to Makefile
++          variables like 'common-objpfx' (the top of the build tree,
++          with a trailing slash), or '..' (the top of the source tree,
++          with a trailing slash).
++
++          The EGLIBC source tree includes a sample configuration file
++          named 'nss/fixed-nsswitch.conf'; for simple configurations,
++          you will probably want to delete references to databases not
++          needed on your system.
++
++config EGLIBC_NSSWITCH_FIXED_FUNCTIONS
++   string "Nsswitch fixed functions filename"

++   help
++          The EGLIBC build process uses this file to decide which
++          functions to make available from which service libraries.
++          The file 'nss/fixed-nsswitch.functions' serves as a sample
++          configuration file for this setting, and explains its syntax
++          and meaning in more detail.
++
++          This should be an absolute file name.  The EGLIBC build
++          process may use it from several different working

++          with a trailing slash).
++
++          Be sure to mention each function in each service you wish to
++          use.  If you do not mention a service's function here, the
++          EGLIBC database access functions will not find it, even if
++          it is listed in the EGLIBC_NSSWITCH_FIXED_CONFIG
++          file.
++
++          In this arrangement, EGLIBC will not use the 'dlopen' and
++          'dlsym' functions to find database access functions.  Instead,
++          libc hard-codes references to the service libraries' database
++          access functions.  You must explicitly link your program
++          against the name service libraries (those whose names start
++          with 'libnss_', in the sysroot's '/lib' directory) whose
++          functions you intend to use.  This arrangement helps
++          system-wide static analysis tools decide which functions a
++          system actually uses.
++
++          Note that some nsswitch service libraries require other option
++          groups to be enabled; for example, the EGLIBC_INET
++          option group must be enabled to use the 'libnss_dns.so.2'
++          service library, which uses the Domain Name System network
++          protocol to answer queries.

++        some of these functions; you will not be able to link or run
++        C++ programs if you disable this option group.
++
++        This option group also affects the behavior of the following

++          fopen64
++          freopen
++          freopen64
++
++        These functions all take an OPENTYPE parameter which may
++        contain a string of the form ",ccs=CHARSET", indicating that
++        the underlying file uses the character set named CHARSET.
++        This produces a wide-oriented stream, which is only useful
++        when the functions included in this option group are present.
++        If the user attempts to open a file specifying a character set
++        in the OPENTYPE parameter, and EGLIBC was built with this
++        option group disabled, the function returns NULL, and sets
++        errno to EINVAL.

++
++/* When OPTION_EGLIBC_NSSWITCH is disabled (see option-groups.def),
++   EGLIBC does not use the 'dlopen' and 'dlsym' functions to look for
++   database query functions in the individual name service libraries.
++   Instead, it uses a set of functions chosen at compile time, as
++   directed by the OPTION_EGLIBC_NSSWITCH_FIXED_FUNCTIONS file.  This
++   file is a sample of what you might use there.
++
++   This file is C source code; it should only contain invocations of
++   the following macros:
++
++   - DEFINE_ENT (DATABASE, SERVICE, X)
++
++     Declare the 'setXent', 'getXent_r', and 'endXent' functions that
++     query DATABASE using the service library 'libnss_SERVICE.so.2'.
++     DATABASE should be the full name of the database as it appears in
++     'nsswitch.conf', like 'passwd' or 'aliases'.
++
++     (The non-reentrant 'getXent' functions are implemented in terms
++     of the reentrant 'getXent_r' functions, so there is no need to
++     refer to them explicitly here.)
++
++   - DEFINE_GETBY (DATABASE, SERVICE, X, KEY)
++
++     Declare the 'getXbyKEY_r' functions that query DATABASE using
++     SERVICE.  DATABASE and SERVICE are as described above.
++
++     (The non-reentrant 'getXbyKEY' functions are implemented in terms
++     of the reentrant 'getXbyKEY_r' functions, so there is no need to
++     refer to them explicitly here.)
++
++     Use the special key 'name3' for the service library function that
++     implements the 'getaddrinfo' function.
++
++   - DEFINE_GET (DATABASE, SERVICE, QUERY)
++
++     Declare the 'getQUERY_r' functions that query DATABASE using
++     SERVICE.  This is used for functions like 'getpwnam'.
++
++     (The non-reentrant 'getQUERY' functions are implemented in terms
++     of the reentrant 'getQUERY_r' functions, so there is no need to
++     refer to them explicitly here.)
++
++   This sample file only includes functions that consult the files in
++   '/etc', and the Domain Name System (DNS).  */

+Quote from bug 1443 which explains what the patch does : 
+
+  We build some random program and link it with -lust.  When we run it,
+  it dies with a SIGSEGV before reaching main().
+  
+  Libust.so depends on liburcu-bp.so from the usermode-rcu package.
+  Although libust.so is not prelinked, liburcu-bp.so IS prelinked; this
+  is critical.
+  
+  Libust.so uses a TLS / __thread variable that is defined in liburcu-
+  bp.so.  There are special ARM-specific relocation types that allow two
+  shared libraries to share thread-specific data.  This is critical too.
+  
+  One more critical issue: although liburcu-bp.so is prelinked, we can't
+  load it at its prelinked address, because we also link against
+  librt.so, and librt.so uses that address.
+  
+  The dynamic linker is forced to relink liburcu-bp.so at a different
+  address.  In the course of relinking, it processes the special ARM
+  relocation record mentioned above.  The prelinker has already filled
+  in the information, which is a short offset into a table of thread-
+  specific data that is allocated per-thread for each library that uses
+  TLS.  Because the normal behavior of a relocation is to add the symbol
+  value to an addend stored at the address being relocated, we end up
+  adding the short offset to itself, doubling it.
+  
+  Now we have an awkward situation.  The libust.so library doesn't know
+  about the addend, so its TLS data for this element is correct.  The
+  liburcu-bp.so library has a different offset for the element.  When we
+  go to initialize the element for the first time in liburcu-bp.so, we
+  write the address of the result at the doubled (broken) offset.
+  Later, when we refer to the address from libust.so, we check the value
+  at the correct offset, but it's NULL, so we eat hot SIGSEGV.

++Introduction
++
++Most GNU tools have a simple build procedure: you run their
++'configure' script, and then you run 'make'.  Unfortunately, the
++process of cross-compiling the GNU C library is quite a bit more
++involved:
++
++1) Build a cross-compiler, with certain facilities disabled.
++
++2) Configure the C library using the compiler you built in step 1).
++   Build a few of the C run-time object files, but not the rest of the
++   library.  Install the library's header files and the run-time
++   object files, and create a dummy libc.so.
++
++3) Build a second cross-compiler, using the header files and object
++   files you installed in step 2.
++
++4) Configure, build, and install a fresh C library, using the compiler
++   built in step 3.
++
++5) Build a third cross-compiler, based on the C library built in step 4.
++
++The reason for this complexity is that, although GCC and the GNU C
++library are distributed separately, they are not actually independent
++of each other: GCC requires the C library's headers and some object
++files to compile its own libraries, while the C library depends on
++GCC's libraries.  GLIBC includes features and bug fixes to the stock
++GNU C library that simplify this process, but the fundamental
++interdependency stands.
++
++In this document, we explain how to cross-compile an GLIBC/GCC pair
++from source.  Our intended audience is developers who are already
++familiar with the GNU toolchain and comfortable working with
++cross-development tools.  While we do present a worked example to
++accompany the explanation, for clarity's sake we do not cover many of
++the options available to cross-toolchain users.
++
++
++Preparation
++
++GLIBC requires recent versions of the GNU binutils, GCC, and the
++Linux kernel.  The web page <http://www.eglibc.org/prerequisites>
++documents the current requirements, and lists patches needed for
++certain target architectures.  As of this writing, these build
++instructions have been tested with binutils 2.22.51, GCC 4.6.2,
++and Linux 3.1.
++
++First, let's set some variables, to simplify later commands.  We'll
++build GLIBC and GCC for an ARM target, known to the Linux kernel
++as 'arm', and we'll do the build on an Intel x86_64 Linux box:
++
++    $ build=x86_64-pc-linux-gnu
++    $ host=$build
++    $ target=arm-none-linux-gnueabi
++    $ linux_arch=arm
++
++We're using the aforementioned versions of Binutils, GCC, and Linux:
++
++    $ binutilsv=binutils-2.22.51
++    $ gccv=gcc-4.6.2
++    $ linuxv=linux-3.1
++
++We're carrying out the entire process under '~/cross-build', which
++contains unpacked source trees for binutils, gcc, and linux kernel,
++along with GLIBC svn trunk (which can be checked-out with
++'svn co http://www.eglibc.org/svn/trunk eglibc'):
++
++    $ top=$HOME/cross-build/$target
++    $ src=$HOME/cross-build/src
++    $ ls $src
++    binutils-2.22.51  glibc  gcc-4.6.2  linux-3.1
++
++We're going to place our build directories in a subdirectory 'obj',
++we'll install the cross-development toolchain in 'tools', and we'll
++place our sysroot (containing files to be installed on the target
++system) in 'sysroot':
++
++    $ obj=$top/obj
++    $ tools=$top/tools
++    $ sysroot=$top/sysroot
++
++
++Binutils
++
++Configuring and building binutils for the target is straightforward:
++
++    $ mkdir -p $obj/binutils
++    $ cd $obj/binutils
++    $ $src/$binutilsv/configure \
++    >     --target=$target \
++    >     --prefix=$tools \
++    >     --with-sysroot=$sysroot
++    $ make
++    $ make install
++
++
++The First GCC
++
++For our work, we need a cross-compiler targeting an ARM Linux
++system.  However, that configuration includes the shared library
++'libgcc_s.so', which is compiled against the GLIBC headers (which we
++haven't installed yet) and linked against 'libc.so' (which we haven't
++built yet).
++
++Fortunately, there are configuration options for GCC which tell it not
++to build 'libgcc_s.so'.  The '--without-headers' option is supposed to
++take care of this, but its implementation is incomplete, so you must
++also configure with the '--with-newlib' option.  While '--with-newlib'
++appears to mean "Use the Newlib C library", its effect is to tell the
++GCC build machinery, "Don't assume there is a C library available."
++
++We also need to disable some of the libraries that would normally be
++built along with GCC, and specify that only the compiler for the C
++language is needed.
++
++So, we create a build directory, configure, make, and install.
++
++    $ mkdir -p $obj/gcc1
++    $ cd $obj/gcc1
++    $ $src/$gccv/configure \
++    >     --target=$target \
++    >     --prefix=$tools \
++    >     --without-headers --with-newlib \
++    >     --disable-shared --disable-threads --disable-libssp \
++    >     --disable-libgomp --disable-libmudflap --disable-libquadmath \
++    >     --disable-decimal-float --disable-libffi \
++    >     --enable-languages=c
++    $ PATH=$tools/bin:$PATH make
++    $ PATH=$tools/bin:$PATH make install
++
++
++Linux Kernel Headers
++
++To configure GLIBC, we also need Linux kernel headers in place.
++Fortunately, the Linux makefiles have a target that installs them for
++us.  Since the process does modify the source tree a bit, we make a
++copy first:
++
++    $ cp -r $src/$linuxv $obj/linux
++    $ cd $obj/linux
++
++Now we're ready to install the headers into the sysroot:
++
++    $ PATH=$tools/bin:$PATH \
++    > make headers_install \
++    >      ARCH=$linux_arch CROSS_COMPILE=$target- \
++    >      INSTALL_HDR_PATH=$sysroot/usr
++
++
++GLIBC Headers and Preliminary Objects
++
++Using the cross-compiler we've just built, we can now configure GLIBC
++well enough to install the headers and build the object files that the
++full cross-compiler will need:
++
++    $ mkdir -p $obj/glibc-headers
++    $ cd $obj/glibc-headers
++    $ BUILD_CC=gcc \
++    > CC=$tools/bin/$target-gcc \
++    > CXX=$tools/bin/$target-g++ \
++    > AR=$tools/bin/$target-ar \
++    > RANLIB=$tools/bin/$target-ranlib \
++    > $src/glibc/libc/configure \
++    >     --prefix=/usr \
++    >     --with-headers=$sysroot/usr/include \
++    >     --build=$build \
++    >     --host=$target \
++    >     --disable-profile --without-gd --without-cvs \
++    >     --enable-add-ons=nptl,libidn,../ports
++
++The option '--prefix=/usr' may look strange, but you should never
++configure GLIBC with a prefix other than '/usr': in various places,
++GLIBC's build system checks whether the prefix is '/usr', and does
++special handling only if that is the case.  Unless you use this
++prefix, you will get a sysroot that does not use the standard Linux
++directory layouts and cannot be used as a basis for the root
++filesystem on your target system compatibly with normal GLIBC
++installations.
++
++The '--with-headers' option tells GLIBC where the Linux headers have
++been installed.
++
++The '--enable-add-ons=nptl,libidn,../ports' option tells GLIBC to look
++for the listed glibc add-ons. Most notably the ports add-on (located
++just above the libc sources in the GLIBC svn tree) is required to
++support ARM targets.
++
++We can now use the 'install-headers' makefile target to install the
++headers:
++
++    $ make install-headers install_root=$sysroot \
++    >                      install-bootstrap-headers=yes
++
++The 'install_root' variable indicates where the files should actually
++be installed; its value is treated as the parent of the '--prefix'
++directory we passed to the configure script, so the headers will go in
++'$sysroot/usr/include'.  The 'install-bootstrap-headers' variable
++requests special handling for certain tricky header files.
++
++Next, there are a few object files needed to link shared libraries,
++which we build and install by hand:
++
++    $ mkdir -p $sysroot/usr/lib
++    $ make csu/subdir_lib
++    $ cp csu/crt1.o csu/crti.o csu/crtn.o $sysroot/usr/lib
++
++Finally, 'libgcc_s.so' requires a 'libc.so' to link against.  However,
++since we will never actually execute its code, it doesn't matter what
++it contains.  So, treating '/dev/null' as a C source file, we produce
++a dummy 'libc.so' in one step:
++
++    $ $tools/bin/$target-gcc -nostdlib -nostartfiles -shared -x c /dev/null \
++    >                        -o $sysroot/usr/lib/libc.so
++
++
++The Second GCC
++
++With the GLIBC headers and selected object files installed, we can
++now build a GCC that is capable of compiling GLIBC.  We configure,
++build, and install the second GCC, again building only the C compiler,
++and avoiding libraries we won't use:
++
++    $ mkdir -p $obj/gcc2
++    $ cd $obj/gcc2
++    $ $src/$gccv/configure \
++    >     --target=$target \
++    >     --prefix=$tools \
++    >     --with-sysroot=$sysroot \
++    >     --disable-libssp --disable-libgomp --disable-libmudflap \
++    >     --disable-libffi --disable-libquadmath \
++    >     --enable-languages=c
++    $ PATH=$tools/bin:$PATH make
++    $ PATH=$tools/bin:$PATH make install
++
++
++GLIBC, Complete
++
++With the second compiler built and installed, we're now ready for the
++full GLIBC build:
++
++    $ mkdir -p $obj/glibc
++    $ cd $obj/glibc
++    $ BUILD_CC=gcc \
++    > CC=$tools/bin/$target-gcc \
++    > CXX=$tools/bin/$target-g++ \
++    > AR=$tools/bin/$target-ar \
++    > RANLIB=$tools/bin/$target-ranlib \
++    > $src/glibc/libc/configure \
++    >     --prefix=/usr \
++    >     --with-headers=$sysroot/usr/include \
++    >     --with-kconfig=$obj/linux/scripts/kconfig \
++    >     --build=$build \
++    >     --host=$target \
++    >     --disable-profile --without-gd --without-cvs \
++    >     --enable-add-ons=nptl,libidn,../ports
++
++Note the additional '--with-kconfig' option. This tells GLIBC where to
++find the host config tools used by the kernel 'make config' and 'make
++menuconfig'.  These tools can be re-used by GLIBC for its own 'make
++*config' support, which will create 'option-groups.config' for you.
++But first make sure those tools have been built by running some
++dummy 'make *config' calls in the kernel directory:
++
++    $ cd $obj/linux
++    $ PATH=$tools/bin:$PATH make config \
++    >      ARCH=$linux_arch CROSS_COMPILE=$target- \
++    $ PATH=$tools/bin:$PATH make menuconfig \
++    >      ARCH=$linux_arch CROSS_COMPILE=$target- \
++
++Now we can configure and build the full GLIBC:
++
++    $ cd $obj/glibc
++    $ PATH=$tools/bin:$PATH make defconfig
++    $ PATH=$tools/bin:$PATH make menuconfig
++    $ PATH=$tools/bin:$PATH make
++    $ PATH=$tools/bin:$PATH make install install_root=$sysroot
++
++At this point, we have a complete GLIBC installation in '$sysroot',
++with header files, library files, and most of the C runtime startup
++files in place.
++
++
++The Third GCC
++
++Finally, we recompile GCC against this full installation, enabling
++whatever languages and libraries we would like to use:
++
++    $ mkdir -p $obj/gcc3
++    $ cd $obj/gcc3
++    $ $src/$gccv/configure \
++    >     --target=$target \
++    >     --prefix=$tools \
++    >     --with-sysroot=$sysroot \
++    >     --enable-__cxa_atexit \
++    >     --disable-libssp --disable-libgomp --disable-libmudflap \
++    >     --enable-languages=c,c++
++    $ PATH=$tools/bin:$PATH make
++    $ PATH=$tools/bin:$PATH make install
++
++The '--enable-__cxa_atexit' option tells GCC what sort of C++
++destructor support to expect from the C library; it's required with
++GLIBC.
++
++And since GCC's installation process isn't designed to help construct
++sysroot trees, we must manually copy certain libraries into place in
++the sysroot.
++
++    $ cp -d $tools/$target/lib/libgcc_s.so* $sysroot/lib
++    $ cp -d $tools/$target/lib/libstdc++.so* $sysroot/usr/lib
++
++
++Trying Things Out
++
++At this point, '$tools' contains a cross toolchain ready to use
++the GLIBC installation in '$sysroot':
++
++    $ cat > hello.c <<EOF
++    > #include <stdio.h>
++    > int
++    > main (int argc, char **argv)
++    > {
++    >   puts ("Hello, world!");
++    >   return 0;
++    > }
++    > EOF
++    $ $tools/bin/$target-gcc -Wall hello.c -o hello
++    $ cat > c++-hello.cc <<EOF
++    > #include <iostream>
++    > int
++    > main (int argc, char **argv)
++    > {
++    >   std::cout << "Hello, C++ world!" << std::endl;
++    >   return 0;
++    > }
++    > EOF
++    $ $tools/bin/$target-g++ -Wall c++-hello.cc -o c++-hello
++
++
++We can use 'readelf' to verify that these are indeed executables for
++our target, using our dynamic linker:
++
++    $ $tools/bin/$target-readelf -hl hello
++    ELF Header:
++    ...
++      Type:                              EXEC (Executable file)
++      Machine:                           ARM
++
++    ...
++    Program Headers:
++      Type           Offset   VirtAddr   PhysAddr   FileSiz MemSiz  Flg Align
++      PHDR           0x000034 0x10000034 0x10000034 0x00100 0x00100 R E 0x4
++      INTERP         0x000134 0x00008134 0x00008134 0x00013 0x00013 R   0x1
++          [Requesting program interpreter: /lib/ld-linux.so.3]
++      LOAD           0x000000 0x00008000 0x00008000 0x0042c 0x0042c R E 0x8000
++    ...
++
++Looking at the dynamic section of the installed 'libgcc_s.so', we see
++that the 'NEEDED' entry for the C library does include the '.6'
++suffix, indicating that was linked against our fully build GLIBC, and
++not our dummy 'libc.so':
++
++    $ $tools/bin/$target-readelf -d $sysroot/lib/libgcc_s.so.1
++    Dynamic section at offset 0x1083c contains 24 entries:
++      Tag        Type                         Name/Value
++     0x00000001 (NEEDED)                     Shared library: [libc.so.6]
++     0x0000000e (SONAME)                     Library soname: [libgcc_s.so.1]
++    ...
++
++
++And on the target machine, we can run our programs:
++
++    $ $sysroot/lib/ld.so.1 --library-path $sysroot/lib:$sysroot/usr/lib \
++    > ./hello
++    Hello, world!
++    $ $sysroot/lib/ld.so.1 --library-path $sysroot/lib:$sysroot/usr/lib \
++    > ./c++-hello
++    Hello, C++ world!

++
++Introduction
++
++Developers writing software for embedded systems often use a desktop
++or other similarly capable computer for development, but need to run
++tests on the embedded system, or perhaps on a simulator.  When
++configured for cross-compilation, the stock GNU C library simply
++disables running tests altogether: the command 'make tests' builds
++test programs, but does not run them.  GLIBC, however, provides
++facilities for compiling tests and generating data files on the build
++system, but running the test programs themselves on a remote system or
++simulator.
++
++
++Test environment requirements
++
++The test environment must meet certain conditions for GLIBC's
++cross-testing facilities to work:
++
++- Shared filesystems.  The 'build' system, on which you configure and
++  compile GLIBC, and the 'host' system, on which you intend to run
++  GLIBC, must share a filesystem containing the GLIBC build and
++  source trees.  Files must appear at the same paths on both systems.
++
++- Remote-shell like invocation.  There must be a way to run a program
++  on the host system from the build system, passing it properly quoted
++  command-line arguments, setting environment variables, and
++  inheriting the caller's standard input and output.
++
++
++Usage
++
++To use GLIBC's cross-testing support, provide values for the
++following Make variables when you invoke 'make':
++
++- cross-test-wrapper
++
++  This should be the name of the cross-testing wrapper command, along
++  with any arguments.
++
++- cross-localedef
++
++  This should be the name of a cross-capable localedef program, like
++  that included in the GLIBC 'localedef' module, along with any
++  arguments needed.
++
++These are each explained in detail below.
++
++
++The Cross-Testing Wrapper
++
++To run test programs reliably, the stock GNU C library takes care to
++ensure that test programs use the newly compiled dynamic linker and
++shared libraries, and never the host system's installed libraries.  To
++accomplish this, it runs the tests by explicitly invoking the dynamic
++linker from the build tree, passing it a list of build tree
++directories to search for shared libraries, followed by the name of
++the executable to run and its arguments.
++
++For example, where one might normally run a test program like this:
++
++    $ ./tst-foo arg1 arg2
++
++the GNU C library might run that program like this:
++
++    $ $objdir/elf/ld-linux.so.3 --library-path $objdir \
++      ./tst-foo arg1 arg2
++
++(where $objdir is the path to the top of the build tree, and the
++trailing backslash indicates a continuation of the command).  In other
++words, each test program invocation is 'wrapped up' inside an explicit
++invocation of the dynamic linker, which must itself execute the test
++program, having loaded shared libraries from the appropriate
++directories.
++
++To support cross-testing, GLIBC allows the developer to optionally
++set the 'cross-test-wrapper' Make variable to another wrapper command,
++to which it passes the entire dynamic linker invocation shown above as
++arguments.  For example, if the developer supplies a wrapper of
++'my-wrapper hostname', then GLIBC would run the test above as
++follows:
++
++    $ my-wrapper hostname \
++      $objdir/elf/ld-linux.so.3 --library-path $objdir \
++      ./tst-foo arg1 arg2
++
++The 'my-wrapper' command is responsible for executing the command
++given on the host system.
++
++Since tests are run in varying directories, the wrapper should either
++be in your command search path, or 'cross-test-wrapper' should give an
++absolute path for the wrapper.
++
++The wrapper must meet several requirements:
++
++- It must preserve the current directory.  As explained above, the
++  build directory tree must be visible on both the build and host
++  systems, at the same path.  The test wrapper must ensure that the
++  current directory it inherits is also inherited by the dynamic
++  linker (and thus the test program itself).
++
++- It must preserve environment variables' values.  Many GLIBC tests
++  set environment variables for test runs; in native testing, it
++  invokes programs like this:
++
++    $ GCONV_PATH=$objdir/iconvdata \
++      $objdir/elf/ld-linux.so.3 --library-path $objdir \
++      ./tst-foo arg1 arg2
++
++  With the cross-testing wrapper, that invocation becomes:
++
++    $ GCONV_PATH=$objdir/iconvdata \
++      my-wrapper hostname \
++      $objdir/elf/ld-linux.so.3 --library-path $objdir \
++      ./tst-foo arg1 arg2
++
++  Here, 'my-wrapper' must ensure that the value it sees for
++  'GCONV_PATH' will be seen by the dynamic linker, and thus 'tst-foo'
++  itself.  (The wrapper supplied with GLIBC simply preserves the
++  values of *all* enviroment variables, with a fixed set of
++  exceptions.)
++
++  If your wrapper is a shell script, take care to correctly propagate
++  environment variables whose values contain spaces and shell
++  metacharacters.
++
++- It must pass the command's arguments, unmodified.  The arguments
++  seen by the test program should be exactly those seen by the wrapper
++  (after whatever arguments are given to the wrapper itself).  The
++  GLIBC test framework performs all needed shell word splitting and
++  expansion (wildcard expansion, parameter substitution, and so on)
++  before invoking the wrapper; further expansion may break the tests.
++
++
++The 'cross-test-ssh.sh' script
++
++If you want to use 'ssh' (or something sufficiently similar) to run
++test programs on your host system, GLIBC includes a shell script,
++'scripts/cross-test-ssh.sh', which you can use as your wrapper
++command.  This script takes care of setting the test command's current
++directory, propagating environment variable values, and carrying
++command-line arguments, all across an 'ssh' connection.  You may even
++supply an alternative to 'ssh' on the command line, if needed.
++
++For more details, pass 'cross-test-ssh.sh' the '--help' option.
++
++
++The Cross-Compiling Locale Definition Command
++
++Some GLIBC tests rely on locales generated especially for the test
++process.  In a native configuration, these tests simply run the
++'localedef' command built by the normal GLIBC build process,
++'locale/localedef', to process and install their locales.  However, in
++a cross-compiling configuration, this 'localedef' is built for the
++host system, not the build system, and since it requires quite a bit
++of memory to run (we have seen it fail on systems with 64MiB of
++memory), it may not be practical to run it on the host system.
++
++If set, GLIBC uses the 'cross-localedef' Make variable as the command
++to run on the build system to process and install locales.  The
++localedef program built from the GLIBC 'localedef' module is
++suitable.
++
++The value of 'cross-localedef' may also include command-line arguments
++to be passed to the program; if you are using GLIBC's 'localedef',
++you may include endianness and 'uint32_t' alignment arguments here.
++
++
++Example
++
++In developing GLIBC's cross-testing facility, we invoked 'make' with
++the following script:
++
++    #!/bin/sh
++
++    srcdir=...
++    test_hostname=...
++    localedefdir=...
++    cross_gxx=...-g++

++Other Cross-Testing Concerns

++
++- Some tests require a C++ cross-compiler; you should set the 'CXX'
++  Make variable to the name of an appropriate cross-compiler.
++
++- Some tests require access to libstdc++.so.6 and libgcc_s.so.1; we
++  simply place copies of these libraries in the top GLIBC build

++              The EGLIBC Component Configuration System
++                  Jim Blandy <jimb@codesourcery.com>
++
++Introduction
++
++The GNU C library (GLIBC) provides a broad range of functionality,
++ranging from internationalization support to transcendental
++mathematical functions.  Its website boasts that "nearly all known and
++useful functions from any other C library are available."  This
++exhaustive approach has been one of GLIBC's strengths on desktop and
++server systems, but it has also given GLIBC a large footprint, both in
++memory and on disk, making it a challenge to use in embedded systems
++with limited resources.
++
++The Embedded GNU C library (EGLIBC) is a variant of the GNU C library
++designed to work well on embedded systems.  In particular, EGLIBC's
++component configuration system allows embedded developers to build
++customized versions of the library that include only the features
++their application uses, reducing its space requirements.
++
++EGLIBC's component configuration system categorizes the library's
++functions into "option groups", and allows you to include or exclude
++option groups individually.  Some option groups depend on others;
++EGLIBC tracks these relationships, and ensures that the selected
++configuration yields a functioning library.
++
++
++Consistent and Predictable Behavior
++
++A flexible configuration system is a mixed blessing: if the options
++offered are poorly designed, it can be hard to see which choices will
++have the desired effects, and choices with obscure consequences can
++make debugging difficult.  EGLIBC's configuration follows some general
++principles to reduce these risks:
++
++- EGLIBC has a single default configuration for each target
++  architecture.
++
++- In the default configuration, all option groups are enabled, and
++  EGLIBC is upwardly API- and ABI-compatible with GLIBC.
++
++- As much as possible, configurations only affect what functions are
++  present, not how they behave.  If the system works with an option
++  group disabled, it will still work with it enabled.
++
++- As much as possible, configurations only select option groups ---
++  they do not describe characteristics of the target architecture.
++
++These rules mean that you have a simple debugging strategy available
++if you suspect that your EGLIBC configuration might be the source of a
++problem: fall back to the default configuration, re-test, and then
++disable option groups one by one, until the problem reappears.
++
++
++The Option Groups
++
++To see the current full list of implemented option groups, refer to the
++file 'option-groups.def' at the top of the source tree, or run
++'make menuconfig' from the top-level build directory.
++
++The POSIX.1-2001 specification includes a suggested partition of all
++the functions in the POSIX C API into option groups: math functions
++like 'sin' and 'cos'; networking functions like 'socket' and
++'connect'; and so on.  EGLIBC could use this partitioning as the basis
++for future option groups.
++
++
++Implementation
++
++The EGLIBC component configuration system resembles the approach used
++by the Linux kernel to select device drivers, network protocols, and
++other features.  A file named 'option-groups.config' in the top-level
++build directory contains assignments to Make variables, each of which
++enables or disables a particular option group.  If the variable's
++value is set to 'y', then the option group is enabled; if it set to
++anything else, the option group is omitted.  The file
++'option-groups.defaults', at the top of the source tree, establishes
++default values for all variables; all option groups are enabled by
++default.
++
++For example, the following 'option-groups.config' would omit locale
++data, but include mathematical functions, and everything else:
++
++   OPTION_EGLIBC_LOCALES = n
++   OPTION_EGLIBC_LIBM = y
++
++Like the Linux kernel, EGLIBC supports a similar set of '*config' make
++targets to make it easier to create 'option-groups.config', with all
++dependencies between option groups automatically satisfied.  Run
++'make help' to see the list of supported make config targets.  For
++example, 'make menuconfig' will update the current config utilising a
++menu based program.
++
++The option group names and their type (boolean, int, hex, string), help
++description, and dependencies with other option groups, are described by
++'option-groups.def' at the top of the source tree, analogous to the
++'Kconfig' files in the Linux kernel.
++
++In general, each option group variable controls whether a given set of
++object files in EGLIBC is compiled and included in the final
++libraries, or omitted from the build.
++
++Each subdirectory's Makefile categorizes its routines, libraries, and
++executables by option group.  For example, EGLIBC's 'math/Makefile'
++places the 'libm' library in the OPTION_EGLIBC_LIBM group as follows:
++
++   extra-libs-$(OPTION_EGLIBC_LIBM) := libm
++
++Finally, common code in 'Makerules' cites the value of the variable
++'extra-libs-y', selecting only those libraries that belong to enabled
++option groups to be built.
++
++
++Current Status and Future Directions
++
++The EGLIBC component configuration system described here is still
++under development.
++
++We have used the system to subset some portions of EGLIBC's

++          libraries to search for database entries as this file
++          specifies, instead of consulting '/etc/nsswitch.conf' at run
++          time.
++
++          This should be an absolute filename.  The EGLIBC build

++          it is listed in the EGLIBC_NSSWITCH_FIXED_CONFIG
++          file.
++
++          In this arrangement, EGLIBC will not use the 'dlopen' and
++          'dlsym' functions to find database access functions.  Instead,
++          libc hard-codes references to the service libraries' database
++          access functions.  You must explicitly link your program

++config POSIX_REGEXP_GLIBC
++    bool "Regular expressions from GLIBC"

++
++        This option group includes the following functions:

++          fwide         putwc         vwprintf
++
++        This option group further includes the following unlocked
++        variants of the above functions:
++
++          fgetwc_unlocked           getwc_unlocked
++          fgetws_unlocked           getwchar_unlocked
++          fputwc_unlocked           putwc_unlocked
++          fputws_unlocked           putwchar_unlocked
++
++        Note that the GNU standard C++ library, 'libstdc++.so', uses
++        some of these functions; you will not be able to link or run
++        C++ programs if you disable this option group.
++
++        This option group also affects the behavior of the following
++        functions:
++
++          fdopen
++          fopen
++          fopen64
++          freopen
++          freopen64
++
++        These functions all take an OPENTYPE parameter which may
++        contain a string of the form ",ccs=CHARSET", indicating that
++        the underlying file uses the character set named CHARSET.
++        This produces a wide-oriented stream, which is only useful
++        when the functions included in this option group are present.
++        If the user attempts to open a file specifying a character set
++        in the OPENTYPE parameter, and EGLIBC was built with this
++        option group disabled, the function returns NULL, and sets
++        errno to EINVAL.

++/* When OPTION_EGLIBC_NSSWITCH is disabled (see option-groups.def),
++   EGLIBC does not use the 'dlopen' and 'dlsym' functions to look for
++   database query functions in the individual name service libraries.
++   Instead, it uses a set of functions chosen at compile time, as
++   directed by the OPTION_EGLIBC_NSSWITCH_FIXED_FUNCTIONS file.  This
++   file is a sample of what you might use there.
++
++   This file is C source code; it should only contain invocations of
++   the following macros:
++
++   - DEFINE_ENT (DATABASE, SERVICE, X)
++
++     Declare the 'setXent', 'getXent_r', and 'endXent' functions that
++     query DATABASE using the service library 'libnss_SERVICE.so.2'.
++     DATABASE should be the full name of the database as it appears in
++     'nsswitch.conf', like 'passwd' or 'aliases'.
++
++     (The non-reentrant 'getXent' functions are implemented in terms
++     of the reentrant 'getXent_r' functions, so there is no need to
++     refer to them explicitly here.)
++
++   - DEFINE_GETBY (DATABASE, SERVICE, X, KEY)
++
++     Declare the 'getXbyKEY_r' functions that query DATABASE using
++     SERVICE.  DATABASE and SERVICE are as described above.
++
++     (The non-reentrant 'getXbyKEY' functions are implemented in terms
++     of the reentrant 'getXbyKEY_r' functions, so there is no need to
++     refer to them explicitly here.)
++
++     Use the special key 'name3' for the service library function that
++     implements the 'getaddrinfo' function.
++
++   - DEFINE_GET (DATABASE, SERVICE, QUERY)
++
++     Declare the 'getQUERY_r' functions that query DATABASE using
++     SERVICE.  This is used for functions like 'getpwnam'.
++
++     (The non-reentrant 'getQUERY' functions are implemented in terms
++     of the reentrant 'getQUERY_r' functions, so there is no need to
++     refer to them explicitly here.)
++
++   This sample file only includes functions that consult the files in
++   '/etc', and the Domain Name System (DNS).  */

+2008-02-07  Joseph Myers  <joseph@codesourcery.com>
+
+        * Makerules (install-extras, install-map): New variables.
+        (installed-libcs): Add libc_pic.a.
+        (install-lib): Include _pic.a files for versioned shared
+        libraries.
+        (install-map-nosubdir, install-extras-nosubdir): Add rules for
+        installing extra files.
+        (install-no-libc.a-nosubdir): Depend on install-map-nosubdir and
+        install-extras-nosubdir.
+
+2008-04-01  Maxim Kuvyrkov  <maxim@codesourcery.com>
+
+        * Makerules (install-lib): Don't install libpthread_pic.a.
+        (install-map): Don't install libpthread_pic.map.

+Subject: [PATCH 27/27] eglibc-use-option-groups: Conditionally exclude c++
+ tests
+
+    Some test programs written in c++ are still included in spite of
+    "libc-cxx-tests" being omitted from DISTRO_FEATURES_LIBC.
+    All .cc programs are compiled with g++.
+    g++ automatically specifies linking against the C++ library.
+    This patch conditionally excludes the following tests as well:
+
+      bug-atexit3-lib.cc
+      tst-cancel24.cc
+      tst-cancel24-static.cc
+      tst-unique3lib.cc
+      tst-unique3lib2.cc
+      tst-unique4lib.cc
+      tst-unique3.cc
+      tst-unique4.cc
+
+    Tested with DISTRO_FEATURES_LIBC_remove = " libc-cxx-tests"
+
+    [YOCTO #7003]

+ * CVE-2104-7817 The wordexp function could ignore the WRDE_NOCMD flag
+   under certain input conditions resulting in the execution of a shell for
+   command substitution when the applicaiton did not request it. The
+   implementation now checks WRDE_NOCMD immediately before executing the
+   shell and returns the error WRDE_CMDSUB as expected.
+ 
++* CVE-2012-3406 printf-style functions could run into a stack overflow when
++  processing format strings with a large number of format specifiers.
++
+ * Reverted change of ABI data structures for s390 and s390x:
+   On s390 and s390x the size of struct ucontext and jmp_buf was increased in
+   2.19. This change is reverted in 2.20. The introduced 2.19 symbol versions

+Subject: [PATCH] CVE-2014-7817: wordexp fails to honour WRDE_NOCMD.
+
+The function wordexp() fails to properly handle the WRDE_NOCMD
+flag when processing arithmetic inputs in the form of "$((... ``))"
+where "..." can be anything valid. The backticks in the arithmetic
+epxression are evaluated by in a shell even if WRDE_NOCMD forbade
+command substitution. This allows an attacker to attempt to pass
+dangerous commands via constructs of the above form, and bypass
+the WRDE_NOCMD flag. This patch fixes this by checking for WRDE_NOCMD
+in exec_comm(), the only place that can execute a shell. All other
+checks for WRDE_NOCMD are superfluous and removed.
+
+We expand the testsuite and add 3 new regression tests of roughly
+the same form but with a couple of nested levels.
+
+On top of the 3 new tests we add fork validation to the WRDE_NOCMD
+testing. If any forks are detected during the execution of a wordexp()
+call with WRDE_NOCMD, the test is marked as failed. This is slightly
+heuristic since vfork might be used in the future, but it provides a
+higher level of assurance that no shells were executed as part of
+command substitution with WRDE_NOCMD in effect. In addition it doesn't
+require libpthread or libdl, instead we use the public implementation
+namespace function __register_atfork (already part of the public ABI
+for libpthread).
+
+Tested on x86_64 with no regressions.

++
++/* When OPTION_EGLIBC_NSSWITCH is disabled (see option-groups.def),
++   EGLIBC does not use the 'dlopen' and 'dlsym' functions to look for
++   database query functions in the individual name service libraries.
++   Instead, it uses a set of functions chosen at compile time, as
++   directed by the OPTION_EGLIBC_NSSWITCH_FIXED_FUNCTIONS file.  This
++   file is a sample of what you might use there.
++
++   This file is C source code; it should only contain invocations of
++   the following macros:
++
++   - DEFINE_ENT (DATABASE, SERVICE, X)
++
++     Declare the 'setXent', 'getXent_r', and 'endXent' functions that
++     query DATABASE using the service library 'libnss_SERVICE.so.2'.
++     DATABASE should be the full name of the database as it appears in
++     'nsswitch.conf', like 'passwd' or 'aliases'.
++
++     (The non-reentrant 'getXent' functions are implemented in terms
++     of the reentrant 'getXent_r' functions, so there is no need to
++     refer to them explicitly here.)
++
++   - DEFINE_GETBY (DATABASE, SERVICE, X, KEY)
++
++     Declare the 'getXbyKEY_r' functions that query DATABASE using
++     SERVICE.  DATABASE and SERVICE are as described above.
++
++     (The non-reentrant 'getXbyKEY' functions are implemented in terms
++     of the reentrant 'getXbyKEY_r' functions, so there is no need to
++     refer to them explicitly here.)
++
++     Use the special key 'name3' for the service library function that
++     implements the 'getaddrinfo' function.
++
++   - DEFINE_GET (DATABASE, SERVICE, QUERY)
++
++     Declare the 'getQUERY_r' functions that query DATABASE using
++     SERVICE.  This is used for functions like 'getpwnam'.
++
++     (The non-reentrant 'getQUERY' functions are implemented in terms
++     of the reentrant 'getQUERY_r' functions, so there is no need to
++     refer to them explicitly here.)
++
++   This sample file only includes functions that consult the files in
++   '/etc', and the Domain Name System (DNS).  */

++
++
++Introduction
++
++Most GNU tools have a simple build procedure: you run their
++'configure' script, and then you run 'make'.  Unfortunately, the
++process of cross-compiling the GNU C library is quite a bit more
++involved:
++
++1) Build a cross-compiler, with certain facilities disabled.
++
++2) Configure the C library using the compiler you built in step 1).
++   Build a few of the C run-time object files, but not the rest of the
++   library.  Install the library's header files and the run-time
++   object files, and create a dummy libc.so.
++
++3) Build a second cross-compiler, using the header files and object
++   files you installed in step 2.
++
++4) Configure, build, and install a fresh C library, using the compiler
++   built in step 3.
++
++5) Build a third cross-compiler, based on the C library built in step 4.
++
++The reason for this complexity is that, although GCC and the GNU C
++library are distributed separately, they are not actually independent
++of each other: GCC requires the C library's headers and some object
++files to compile its own libraries, while the C library depends on
++GCC's libraries.  EGLIBC includes features and bug fixes to the stock
++GNU C library that simplify this process, but the fundamental
++interdependency stands.
++
++In this document, we explain how to cross-compile an EGLIBC/GCC pair
++from source.  Our intended audience is developers who are already
++familiar with the GNU toolchain and comfortable working with
++cross-development tools.  While we do present a worked example to
++accompany the explanation, for clarity's sake we do not cover many of
++the options available to cross-toolchain users.
++
++
++Preparation
++
++EGLIBC requires recent versions of the GNU binutils, GCC, and the
++Linux kernel.  The web page <http://www.eglibc.org/prerequisites>
++documents the current requirements, and lists patches needed for
++certain target architectures.  As of this writing, these build
++instructions have been tested with binutils 2.22.51, GCC 4.6.2,
++and Linux 3.1.
++
++First, let's set some variables, to simplify later commands.  We'll
++build EGLIBC and GCC for an ARM target, known to the Linux kernel
++as 'arm', and we'll do the build on an Intel x86_64 Linux box:
++
++    $ build=x86_64-pc-linux-gnu
++    $ host=$build
++    $ target=arm-none-linux-gnueabi
++    $ linux_arch=arm
++
++We're using the aforementioned versions of Binutils, GCC, and Linux:
++
++    $ binutilsv=binutils-2.22.51
++    $ gccv=gcc-4.6.2
++    $ linuxv=linux-3.1
++
++We're carrying out the entire process under '~/cross-build', which
++contains unpacked source trees for binutils, gcc, and linux kernel,
++along with EGLIBC svn trunk (which can be checked-out with
++'svn co http://www.eglibc.org/svn/trunk eglibc'):
++
++    $ top=$HOME/cross-build/$target
++    $ src=$HOME/cross-build/src
++    $ ls $src
++    binutils-2.22.51  eglibc  gcc-4.6.2  linux-3.1
++
++We're going to place our build directories in a subdirectory 'obj',
++we'll install the cross-development toolchain in 'tools', and we'll
++place our sysroot (containing files to be installed on the target
++system) in 'sysroot':
++
++    $ obj=$top/obj
++    $ tools=$top/tools
++    $ sysroot=$top/sysroot
++
++
++Binutils
++
++Configuring and building binutils for the target is straightforward:
++
++    $ mkdir -p $obj/binutils
++    $ cd $obj/binutils
++    $ $src/$binutilsv/configure \
++    >     --target=$target \
++    >     --prefix=$tools \
++    >     --with-sysroot=$sysroot
++    $ make
++    $ make install
++
++
++The First GCC
++
++For our work, we need a cross-compiler targeting an ARM Linux
++system.  However, that configuration includes the shared library
++'libgcc_s.so', which is compiled against the EGLIBC headers (which we
++haven't installed yet) and linked against 'libc.so' (which we haven't
++built yet).
++
++Fortunately, there are configuration options for GCC which tell it not
++to build 'libgcc_s.so'.  The '--without-headers' option is supposed to
++take care of this, but its implementation is incomplete, so you must
++also configure with the '--with-newlib' option.  While '--with-newlib'
++appears to mean "Use the Newlib C library", its effect is to tell the
++GCC build machinery, "Don't assume there is a C library available."
++
++We also need to disable some of the libraries that would normally be
++built along with GCC, and specify that only the compiler for the C
++language is needed.
++
++So, we create a build directory, configure, make, and install.
++
++    $ mkdir -p $obj/gcc1
++    $ cd $obj/gcc1
++    $ $src/$gccv/configure \
++    >     --target=$target \
++    >     --prefix=$tools \
++    >     --without-headers --with-newlib \
++    >     --disable-shared --disable-threads --disable-libssp \
++    >     --disable-libgomp --disable-libmudflap --disable-libquadmath \
++    >     --disable-decimal-float --disable-libffi \
++    >     --enable-languages=c
++    $ PATH=$tools/bin:$PATH make
++    $ PATH=$tools/bin:$PATH make install
++
++
++Linux Kernel Headers
++
++To configure EGLIBC, we also need Linux kernel headers in place.
++Fortunately, the Linux makefiles have a target that installs them for
++us.  Since the process does modify the source tree a bit, we make a
++copy first:
++
++    $ cp -r $src/$linuxv $obj/linux
++    $ cd $obj/linux
++
++Now we're ready to install the headers into the sysroot:
++
++    $ PATH=$tools/bin:$PATH \
++    > make headers_install \
++    >      ARCH=$linux_arch CROSS_COMPILE=$target- \
++    >      INSTALL_HDR_PATH=$sysroot/usr
++
++
++EGLIBC Headers and Preliminary Objects
++
++Using the cross-compiler we've just built, we can now configure EGLIBC
++well enough to install the headers and build the object files that the
++full cross-compiler will need:
++
++    $ mkdir -p $obj/eglibc-headers
++    $ cd $obj/eglibc-headers
++    $ BUILD_CC=gcc \
++    > CC=$tools/bin/$target-gcc \
++    > CXX=$tools/bin/$target-g++ \
++    > AR=$tools/bin/$target-ar \
++    > RANLIB=$tools/bin/$target-ranlib \
++    > $src/eglibc/libc/configure \
++    >     --prefix=/usr \
++    >     --with-headers=$sysroot/usr/include \
++    >     --build=$build \
++    >     --host=$target \
++    >     --disable-profile --without-gd --without-cvs \
++    >     --enable-add-ons=nptl,libidn,../ports
++
++The option '--prefix=/usr' may look strange, but you should never
++configure EGLIBC with a prefix other than '/usr': in various places,
++EGLIBC's build system checks whether the prefix is '/usr', and does
++special handling only if that is the case.  Unless you use this
++prefix, you will get a sysroot that does not use the standard Linux
++directory layouts and cannot be used as a basis for the root
++filesystem on your target system compatibly with normal GLIBC
++installations.
++
++The '--with-headers' option tells EGLIBC where the Linux headers have
++been installed.
++
++The '--enable-add-ons=nptl,libidn,../ports' option tells EGLIBC to look
++for the listed glibc add-ons. Most notably the ports add-on (located
++just above the libc sources in the EGLIBC svn tree) is required to
++support ARM targets.
++
++We can now use the 'install-headers' makefile target to install the
++headers:
++
++    $ make install-headers install_root=$sysroot \
++    >                      install-bootstrap-headers=yes
++
++The 'install_root' variable indicates where the files should actually
++be installed; its value is treated as the parent of the '--prefix'
++directory we passed to the configure script, so the headers will go in
++'$sysroot/usr/include'.  The 'install-bootstrap-headers' variable
++requests special handling for certain tricky header files.
++
++Next, there are a few object files needed to link shared libraries,
++which we build and install by hand:
++
++    $ mkdir -p $sysroot/usr/lib
++    $ make csu/subdir_lib
++    $ cp csu/crt1.o csu/crti.o csu/crtn.o $sysroot/usr/lib
++
++Finally, 'libgcc_s.so' requires a 'libc.so' to link against.  However,
++since we will never actually execute its code, it doesn't matter what
++it contains.  So, treating '/dev/null' as a C source file, we produce
++a dummy 'libc.so' in one step:
++
++    $ $tools/bin/$target-gcc -nostdlib -nostartfiles -shared -x c /dev/null \
++    >                        -o $sysroot/usr/lib/libc.so
++
++
++The Second GCC
++
++With the EGLIBC headers and selected object files installed, we can
++now build a GCC that is capable of compiling EGLIBC.  We configure,
++build, and install the second GCC, again building only the C compiler,
++and avoiding libraries we won't use:
++
++    $ mkdir -p $obj/gcc2
++    $ cd $obj/gcc2
++    $ $src/$gccv/configure \
++    >     --target=$target \
++    >     --prefix=$tools \
++    >     --with-sysroot=$sysroot \
++    >     --disable-libssp --disable-libgomp --disable-libmudflap \
++    >     --disable-libffi --disable-libquadmath \
++    >     --enable-languages=c
++    $ PATH=$tools/bin:$PATH make
++    $ PATH=$tools/bin:$PATH make install
++
++
++EGLIBC, Complete
++
++With the second compiler built and installed, we're now ready for the
++full EGLIBC build:
++
++    $ mkdir -p $obj/eglibc
++    $ cd $obj/eglibc
++    $ BUILD_CC=gcc \
++    > CC=$tools/bin/$target-gcc \
++    > CXX=$tools/bin/$target-g++ \
++    > AR=$tools/bin/$target-ar \
++    > RANLIB=$tools/bin/$target-ranlib \
++    > $src/eglibc/libc/configure \
++    >     --prefix=/usr \
++    >     --with-headers=$sysroot/usr/include \
++    >     --with-kconfig=$obj/linux/scripts/kconfig \
++    >     --build=$build \
++    >     --host=$target \
++    >     --disable-profile --without-gd --without-cvs \
++    >     --enable-add-ons=nptl,libidn,../ports
++
++Note the additional '--with-kconfig' option. This tells EGLIBC where to
++find the host config tools used by the kernel 'make config' and 'make
++menuconfig'.  These tools can be re-used by EGLIBC for its own 'make
++*config' support, which will create 'option-groups.config' for you.
++But first make sure those tools have been built by running some
++dummy 'make *config' calls in the kernel directory:
++
++    $ cd $obj/linux
++    $ PATH=$tools/bin:$PATH make config \
++    >      ARCH=$linux_arch CROSS_COMPILE=$target- \
++    $ PATH=$tools/bin:$PATH make menuconfig \
++    >      ARCH=$linux_arch CROSS_COMPILE=$target- \
++
++Now we can configure and build the full EGLIBC:
++
++    $ cd $obj/eglibc
++    $ PATH=$tools/bin:$PATH make defconfig
++    $ PATH=$tools/bin:$PATH make menuconfig
++    $ PATH=$tools/bin:$PATH make
++    $ PATH=$tools/bin:$PATH make install install_root=$sysroot
++
++At this point, we have a complete EGLIBC installation in '$sysroot',
++with header files, library files, and most of the C runtime startup
++files in place.
++
++
++The Third GCC
++
++Finally, we recompile GCC against this full installation, enabling
++whatever languages and libraries we would like to use:
++
++    $ mkdir -p $obj/gcc3
++    $ cd $obj/gcc3
++    $ $src/$gccv/configure \
++    >     --target=$target \
++    >     --prefix=$tools \
++    >     --with-sysroot=$sysroot \
++    >     --enable-__cxa_atexit \
++    >     --disable-libssp --disable-libgomp --disable-libmudflap \
++    >     --enable-languages=c,c++
++    $ PATH=$tools/bin:$PATH make
++    $ PATH=$tools/bin:$PATH make install
++
++The '--enable-__cxa_atexit' option tells GCC what sort of C++
++destructor support to expect from the C library; it's required with
++EGLIBC.
++
++And since GCC's installation process isn't designed to help construct
++sysroot trees, we must manually copy certain libraries into place in
++the sysroot.
++
++    $ cp -d $tools/$target/lib/libgcc_s.so* $sysroot/lib
++    $ cp -d $tools/$target/lib/libstdc++.so* $sysroot/usr/lib
++
++
++Trying Things Out
++
++At this point, '$tools' contains a cross toolchain ready to use
++the EGLIBC installation in '$sysroot':
++
++    $ cat > hello.c <<EOF
++    > #include <stdio.h>
++    > int
++    > main (int argc, char **argv)
++    > {
++    >   puts ("Hello, world!");
++    >   return 0;
++    > }
++    > EOF
++    $ $tools/bin/$target-gcc -Wall hello.c -o hello
++    $ cat > c++-hello.cc <<EOF
++    > #include <iostream>
++    > int
++    > main (int argc, char **argv)
++    > {
++    >   std::cout << "Hello, C++ world!" << std::endl;
++    >   return 0;
++    > }
++    > EOF
++    $ $tools/bin/$target-g++ -Wall c++-hello.cc -o c++-hello
++
++
++We can use 'readelf' to verify that these are indeed executables for
++our target, using our dynamic linker:
++
++    $ $tools/bin/$target-readelf -hl hello
++    ELF Header:
++    ...
++      Type:                              EXEC (Executable file)
++      Machine:                           ARM
++
++    ...
++    Program Headers:
++      Type           Offset   VirtAddr   PhysAddr   FileSiz MemSiz  Flg Align
++      PHDR           0x000034 0x10000034 0x10000034 0x00100 0x00100 R E 0x4
++      INTERP         0x000134 0x00008134 0x00008134 0x00013 0x00013 R   0x1
++          [Requesting program interpreter: /lib/ld-linux.so.3]
++      LOAD           0x000000 0x00008000 0x00008000 0x0042c 0x0042c R E 0x8000
++    ...
++
++Looking at the dynamic section of the installed 'libgcc_s.so', we see
++that the 'NEEDED' entry for the C library does include the '.6'
++suffix, indicating that was linked against our fully build EGLIBC, and
++not our dummy 'libc.so':
++
++    $ $tools/bin/$target-readelf -d $sysroot/lib/libgcc_s.so.1
++    Dynamic section at offset 0x1083c contains 24 entries:

++
++
++And on the target machine, we can run our programs:
++
++    $ $sysroot/lib/ld.so.1 --library-path $sysroot/lib:$sysroot/usr/lib \
++    > ./hello

++
++Introduction
++
++Developers writing software for embedded systems often use a desktop
++or other similarly capable computer for development, but need to run
++tests on the embedded system, or perhaps on a simulator.  When
++configured for cross-compilation, the stock GNU C library simply
++disables running tests altogether: the command 'make tests' builds
++test programs, but does not run them.  EGLIBC, however, provides
++facilities for compiling tests and generating data files on the build
++system, but running the test programs themselves on a remote system or
++simulator.
++
++
++Test environment requirements
++
++The test environment must meet certain conditions for EGLIBC's
++cross-testing facilities to work:
++
++- Shared filesystems.  The 'build' system, on which you configure and
++  compile EGLIBC, and the 'host' system, on which you intend to run
++  EGLIBC, must share a filesystem containing the EGLIBC build and
++  source trees.  Files must appear at the same paths on both systems.
++
++- Remote-shell like invocation.  There must be a way to run a program
++  on the host system from the build system, passing it properly quoted
++  command-line arguments, setting environment variables, and
++  inheriting the caller's standard input and output.
++
++
++Usage
++
++To use EGLIBC's cross-testing support, provide values for the
++following Make variables when you invoke 'make':
++
++- cross-test-wrapper
++
++  This should be the name of the cross-testing wrapper command, along
++  with any arguments.
++
++- cross-localedef
++
++  This should be the name of a cross-capable localedef program, like
++  that included in the EGLIBC 'localedef' module, along with any
++  arguments needed.
++
++These are each explained in detail below.
++
++
++The Cross-Testing Wrapper
++
++To run test programs reliably, the stock GNU C library takes care to
++ensure that test programs use the newly compiled dynamic linker and
++shared libraries, and never the host system's installed libraries.  To
++accomplish this, it runs the tests by explicitly invoking the dynamic
++linker from the build tree, passing it a list of build tree
++directories to search for shared libraries, followed by the name of
++the executable to run and its arguments.
++
++For example, where one might normally run a test program like this:
++
++    $ ./tst-foo arg1 arg2
++
++the GNU C library might run that program like this:
++
++    $ $objdir/elf/ld-linux.so.3 --library-path $objdir \
++      ./tst-foo arg1 arg2
++
++(where $objdir is the path to the top of the build tree, and the
++trailing backslash indicates a continuation of the command).  In other
++words, each test program invocation is 'wrapped up' inside an explicit
++invocation of the dynamic linker, which must itself execute the test
++program, having loaded shared libraries from the appropriate
++directories.
++
++To support cross-testing, EGLIBC allows the developer to optionally
++set the 'cross-test-wrapper' Make variable to another wrapper command,
++to which it passes the entire dynamic linker invocation shown above as
++arguments.  For example, if the developer supplies a wrapper of
++'my-wrapper hostname', then EGLIBC would run the test above as
++follows:
++
++    $ my-wrapper hostname \
++      $objdir/elf/ld-linux.so.3 --library-path $objdir \
++      ./tst-foo arg1 arg2
++
++The 'my-wrapper' command is responsible for executing the command
++given on the host system.
++
++Since tests are run in varying directories, the wrapper should either
++be in your command search path, or 'cross-test-wrapper' should give an
++absolute path for the wrapper.
++
++The wrapper must meet several requirements:
++
++- It must preserve the current directory.  As explained above, the
++  build directory tree must be visible on both the build and host
++  systems, at the same path.  The test wrapper must ensure that the
++  current directory it inherits is also inherited by the dynamic
++  linker (and thus the test program itself).
++
++- It must preserve environment variables' values.  Many EGLIBC tests
++  set environment variables for test runs; in native testing, it
++  invokes programs like this:
++
++    $ GCONV_PATH=$objdir/iconvdata \
++      $objdir/elf/ld-linux.so.3 --library-path $objdir \
++      ./tst-foo arg1 arg2
++
++  With the cross-testing wrapper, that invocation becomes:
++
++    $ GCONV_PATH=$objdir/iconvdata \
++      my-wrapper hostname \
++      $objdir/elf/ld-linux.so.3 --library-path $objdir \
++      ./tst-foo arg1 arg2
++
++  Here, 'my-wrapper' must ensure that the value it sees for
++  'GCONV_PATH' will be seen by the dynamic linker, and thus 'tst-foo'
++  itself.  (The wrapper supplied with GLIBC simply preserves the
++  values of *all* enviroment variables, with a fixed set of
++  exceptions.)
++
++  If your wrapper is a shell script, take care to correctly propagate
++  environment variables whose values contain spaces and shell
++  metacharacters.
++
++- It must pass the command's arguments, unmodified.  The arguments
++  seen by the test program should be exactly those seen by the wrapper
++  (after whatever arguments are given to the wrapper itself).  The
++  EGLIBC test framework performs all needed shell word splitting and
++  expansion (wildcard expansion, parameter substitution, and so on)
++  before invoking the wrapper; further expansion may break the tests.
++
++
++The 'cross-test-ssh.sh' script
++
++If you want to use 'ssh' (or something sufficiently similar) to run
++test programs on your host system, EGLIBC includes a shell script,
++'scripts/cross-test-ssh.sh', which you can use as your wrapper
++command.  This script takes care of setting the test command's current
++directory, propagating environment variable values, and carrying
++command-line arguments, all across an 'ssh' connection.  You may even
++supply an alternative to 'ssh' on the command line, if needed.
++
++For more details, pass 'cross-test-ssh.sh' the '--help' option.
++
++
++The Cross-Compiling Locale Definition Command
++
++Some EGLIBC tests rely on locales generated especially for the test
++process.  In a native configuration, these tests simply run the
++'localedef' command built by the normal EGLIBC build process,
++'locale/localedef', to process and install their locales.  However, in
++a cross-compiling configuration, this 'localedef' is built for the
++host system, not the build system, and since it requires quite a bit
++of memory to run (we have seen it fail on systems with 64MiB of
++memory), it may not be practical to run it on the host system.
++
++If set, EGLIBC uses the 'cross-localedef' Make variable as the command
++to run on the build system to process and install locales.  The
++localedef program built from the EGLIBC 'localedef' module is
++suitable.
++
++The value of 'cross-localedef' may also include command-line arguments
++to be passed to the program; if you are using EGLIBC's 'localedef',
++you may include endianness and 'uint32_t' alignment arguments here.
++
++
++Example
++
++In developing EGLIBC's cross-testing facility, we invoked 'make' with
++the following script:
++
++    #!/bin/sh
++
++    srcdir=...
++    test_hostname=...
++    localedefdir=...
++    cross_gxx=...-g++
++
++    wrapper="$srcdir/scripts/cross-test-ssh.sh $test_hostname"
++    localedef="$localedefdir/localedef --little-endian --uint32-align=4"
++
++    make cross-test-wrapper="$wrapper" \
++         cross-localedef="$localedef" \
++         CXX="$cross_gxx" \
++         "$@"
++
++
++Other Cross-Testing Concerns
++
++Here are notes on some other issues which you may encounter in running
++the EGLIBC tests in a cross-compiling environment:
++
++- Some tests require a C++ cross-compiler; you should set the 'CXX'
++  Make variable to the name of an appropriate cross-compiler.
++
++- Some tests require access to libstdc++.so.6 and libgcc_s.so.1; we
++  simply place copies of these libraries in the top EGLIBC build
++  directory.

+Subject: [PATCH] intl: Merge with gettext version 0.19.3
+
+This patch merges the latest release of gettext into the intl
+subdirectory. The initial motivation was to include the plural.y
+changes which enable building with bison 3.0, but the majority
+of the other changes are merely cosmetic so it seemed like merging
+the whole directory was simpler than trying to take it piecemeal.
+
+The merge was done by copying across the latext gettext code and
+adding in a few small glibc changes that have been added over the
+years that seemed beneficial, as well as a couple of small build
+fixes that should be merged back to gettext. I also reverted the
+gettext commit:
+
+commit 279b57fc367251666f00e8e2b599b83703451afb
+Author: Bruno Haible <bruno@clisp.org>
+Date:   Fri Jun 14 12:03:49 2002 +0000
+
+    Make absolute pathnames inside $LANGUAGE work.
+
+As it caused localedata/tst-setlocale3 to fail and it wasn't clear
+that glibc wanted that behaviour.
+
+The merge has dropped many uses of __glibc_likely/unlikely. This is
+intentional given that it eases merging. It seems to me that the cost
+of continually rewriting these lines when merging and the risk of adding
+bugs when doing so outweighs the benefits of using these macros when
+code is shared with another project.
+
+Tested with make check on x86_64.
+
+ChangeLog:
+
+2014-12-11  Will Newton  <will.newton@linaro.org>
+
+	Merge gettext 0.19.3 into intl/.
+
+	This involves a number of cosmetic changes to comments
+	and ANSI function definitions and prototypes throughout
+	all the files. The gettext copyright header is used but
+	with the date ranges taken from the glibc copy.
+
+	* NEWS: Add gettext merge to 2.21.
+	* intl/bindtextdom.c: Switch to gettext copyright.
+	Use ANSI definitions and prototypes.
+	Use gl_* locking primitives rather than __libc_* ones.
+	Use __builtin_expect rather than __glibc_likely/unlikely.
+	* intl/dcgettext.c: Switch to gettext copyright.
+	Use ANSI definitions and prototypes.
+	* intl/dcigettext.c: Switch to gettext copyright.
+	Use ANSI definitions and prototypes.
+	(INTDIV0_RAISES_SIGFPE): New define.
+	Use gl_* locking primitives rather than __libc_* ones.
+	Include eval-plural.h instead of plural-eval.c.

+	Use ANSI definitions and prototypes.
+	* intl/dgettext.c: Likewise.
+	* intl/dngettext.c: Likewise.

+	Use ANSI definitions and prototypes.
+	(_nl_explode_name): Use strchr instead of __rawmemchr.
+	* intl/finddomain.c: Switch to gettext copyright.
+	Use ANSI definitions and prototypes.
+	Use gl_* locking primitives rather than __libc_* ones.
+	(_nl_find_domain): Use malloc rather than alloca for
+	allocation of temporary locale name.
+	* intl/gettext.c: Switch to gettext copyright.
+	Use ANSI definitions and prototypes.
+	* intl/gettextP.h: Switch to gettext copyright.
+	Use ANSI definitions and prototypes.
+	Use gl_* locking primitives rather than __libc_* ones.
+	* intl/gmo.h: Switch to gettext copyright.
+	(struct sysdep_string): Move struct segment_pair outside of
+	struct definition.
+	* intl/hash-string.c: Use ANSI definitions and prototypes.
+	* intl/hash-string.h: Switch to gettext copyright.
+	Use ANSI definitions and prototypes.
+	* intl/l10nflist.c: Switch to gettext copyright.
+	Use ANSI definitions and prototypes.
+	(_nl_normalize_codeset): Avoid integer overflow.
+	* intl/loadinfo.h: Switch to gettext copyright.
+	Use ANSI definitions and prototypes.
+	(LIBINTL_DLL_EXPORTED): New define.
+	(PATH_SEPARATOR): New define.
+	* intl/loadmsgcat.c: Switch to gettext copyright.
+	* intl/localealias.c: Switch to gettext copyright.
+	Use ANSI definitions and prototypes.
+	(_nl_expand_alias): Use PATH_SEPARATOR.
+	* intl/ngettext.c: Switch to gettext copyright.
+	Use ANSI definitions and prototypes.
+	* intl/plural-exp.c: Likewise.
+	* intl/plural-exp.h: Switch to gettext copyright.
+	Use ANSI definitions and prototypes.
+	(struct expression): Move definition of enum operator outside
+	of struct definition.
+	* intl/plural.c: Regenerate.
+	* intl/plural.y: Switch to gettext copyright.
+	Use ANSI definitions and prototypes.
+	Port to bison 3.0.
+	* intl/textdomain.c: Switch to gettext copyright.
+	Use ANSI definitions and prototypes.
+	Use gl_* locking primitives rather than __libc_* ones.

+Upstream-Status: Inappropriate [embedded specific]
+
+The default lib search path order is:
+
+  1) LD_LIBRARY_PATH
+  2) RPATH from the binary
+  3) ld.so.cache
+  4) default search paths embedded in the linker
+
+For nativesdk binaries which are being used alongside binaries on a host system, we 
+need the search paths to firstly search the shipped nativesdk libs but then also
+cover the host system. For example we want the host system's libGL and this may be
+in a non-standard location like /usr/lib/mesa. The only place the location is know 
+about is in the ld.so.cache of the host system.
+
+Since nativesdk has a simple structure and doesn't need to use a cache itself, we 
+repurpose the cache for use as a last resort in finding host system binaries. This 
+means we need to switch the order of 3 and 4 above to make this work effectively.

++# This file documents the option groups EGLIBC currently supports, in
++# a format akin to the Linux Kconfig system's.  The syntax may change
++# over time.
++#
++# An entry of the form:
++#
++#   config GROUP_NAME
++#       bool "one-line explanation of what this option group controls"
++#       help
++#           Multi-line help explaining the option group's meaning in
++#           some detail, terminated by indentation level.
++#
++# defines an option group whose variable is GROUP_NAME, with
++# meaningful values 'y' (enabled) and 'n' (disabled).  The
++# documentation is formatted to be consumed by some sort of
++# interactive configuration interface, but EGLIBC doesn't have such an
++# interface yet.
++#
++# An option may have a 'depends on' line, indicating which other options
++# must also be enabled if this option is.  At present, EGLIBC doesn't
++# check that these dependencies are satisfied.
++#
++# Option group variables get their default values from the file
++# 'option-groups.defaults', in the top directory of the EGLIBC source
++# tree.  By default, all EGLIBC option groups are enabled --- their
++# variables are set to 'y'.
++#
++# After including 'option-groups.defaults', the EGLIBC make machinery
++# includes the file 'option-groups.config' from the top of the build
++# tree, if it is present.  Developers can place assignments to option
++# group variables in that file to override the defaults.  For example,
++# to disable an option group, place a line of the form:
++#
++#    OPTION_GROUP_NAME = n
++#
++# in 'option-groups.config' at the top of your build tree.  To
++# explicitly enable an option group, you may also write:
++#
++#    OPTION_GROUP_NAME = y
++#
++# although this simply reestablishes the value already set by
++# 'option-groups.defaults'.

++       IPv6".
++
++       This option group includes the following functions:

++
++       This option group includes the following functions:

++         backtrace_symbols
++         backtrace_symbols_fd
++
++config EGLIBC_BIG_MACROS

++   help
++       This option group specifies whether certain pieces of code
++       should be inlined to achieve maximum speed.  If this option
++       group is not selected, function calls will be used instead,
++       hence reducing the library footprint.
++
++config EGLIBC_BSD
++   bool "BSD-specific functions, and their compatibility stubs"
++   help
++       This option group includes functions specific to BSD kernels.
++       A number of these functions have stub versions that are also

++
++config EGLIBC_NSSWITCH_FIXED_CONFIG
++   string "Nsswitch fixed config filename"

++   default ""

++          EGLIBC build process parses this file just as EGLIBC would
++          at run time if EGLIBC_NSSWITCH were enabled, and
++          produces a C library that uses the nsswitch service
++          libraries to search for database entries as this file
++          specifies, instead of consulting '/etc/nsswitch.conf' at run
++          time.
++
++          This should be an absolute filename.  The EGLIBC build

++
++          Be sure to mention each function in each service you wish to

++          EGLIBC database access functions will not find it, even if
++          it is listed in the EGLIBC_NSSWITCH_FIXED_CONFIG
++          file.
++
++          In this arrangement, EGLIBC will not use the 'dlopen' and
++          'dlsym' functions to find database access functions.  Instead,
++          libc hard-codes references to the service libraries' database
++          access functions.  You must explicitly link your program

++
++        Furthermore, the compatibility regexp interface defined in the

++    help
++	This option group specifies which regular expression
++        library to use.  The choice is between regex
++        implementation from GLIBC and regex implementation from
++        libiberty.  The GLIBC variant is fully POSIX conformant and
++        optimized for speed; regex from libiberty is more than twice
++        as small while still is enough for most practical purposes.

++
++        This option group includes the following functions:

++          fgetws        fwscanf       ungetwc       wprintf

++          fwide         putwc         vwprintf
++
++        This option group further includes the following unlocked
++        variants of the above functions:
++
++          fgetwc_unlocked           getwc_unlocked
++          fgetws_unlocked           getwchar_unlocked
++          fputwc_unlocked           putwc_unlocked
++          fputws_unlocked           putwchar_unlocked
++
++        Note that the GNU standard C++ library, 'libstdc++.so', uses
++        some of these functions; you will not be able to link or run
++        C++ programs if you disable this option group.
++
++        This option group also affects the behavior of the following
++        functions:
++
++          fdopen
++          fopen
++          fopen64
++          freopen
++          freopen64
++
++        These functions all take an OPENTYPE parameter which may
++        contain a string of the form ",ccs=CHARSET", indicating that
++        the underlying file uses the character set named CHARSET.
++        This produces a wide-oriented stream, which is only useful
++        when the functions included in this option group are present.
++        If the user attempts to open a file specifying a character set
++        in the OPENTYPE parameter, and EGLIBC was built with this
++        option group disabled, the function returns NULL, and sets
++        errno to EINVAL.

++              The EGLIBC Component Configuration System
++                  Jim Blandy <jimb@codesourcery.com>
++
++Introduction
++
++The GNU C library (GLIBC) provides a broad range of functionality,
++ranging from internationalization support to transcendental
++mathematical functions.  Its website boasts that "nearly all known and
++useful functions from any other C library are available."  This
++exhaustive approach has been one of GLIBC's strengths on desktop and
++server systems, but it has also given GLIBC a large footprint, both in
++memory and on disk, making it a challenge to use in embedded systems
++with limited resources.
++
++The Embedded GNU C library (EGLIBC) is a variant of the GNU C library
++designed to work well on embedded systems.  In particular, EGLIBC's
++component configuration system allows embedded developers to build
++customized versions of the library that include only the features
++their application uses, reducing its space requirements.
++
++EGLIBC's component configuration system categorizes the library's
++functions into "option groups", and allows you to include or exclude
++option groups individually.  Some option groups depend on others;
++EGLIBC tracks these relationships, and ensures that the selected
++configuration yields a functioning library.
++
++
++Consistent and Predictable Behavior
++
++A flexible configuration system is a mixed blessing: if the options
++offered are poorly designed, it can be hard to see which choices will
++have the desired effects, and choices with obscure consequences can
++make debugging difficult.  EGLIBC's configuration follows some general
++principles to reduce these risks:
++
++- EGLIBC has a single default configuration for each target
++  architecture.
++
++- In the default configuration, all option groups are enabled, and
++  EGLIBC is upwardly API- and ABI-compatible with GLIBC.
++
++- As much as possible, configurations only affect what functions are
++  present, not how they behave.  If the system works with an option
++  group disabled, it will still work with it enabled.
++
++- As much as possible, configurations only select option groups ---
++  they do not describe characteristics of the target architecture.
++
++These rules mean that you have a simple debugging strategy available
++if you suspect that your EGLIBC configuration might be the source of a
++problem: fall back to the default configuration, re-test, and then
++disable option groups one by one, until the problem reappears.
++
++
++The Option Groups
++
++To see the current full list of implemented option groups, refer to the
++file 'option-groups.def' at the top of the source tree, or run
++'make menuconfig' from the top-level build directory.
++
++The POSIX.1-2001 specification includes a suggested partition of all
++the functions in the POSIX C API into option groups: math functions
++like 'sin' and 'cos'; networking functions like 'socket' and
++'connect'; and so on.  EGLIBC could use this partitioning as the basis
++for future option groups.
++
++
++Implementation
++
++The EGLIBC component configuration system resembles the approach used
++by the Linux kernel to select device drivers, network protocols, and
++other features.  A file named 'option-groups.config' in the top-level
++build directory contains assignments to Make variables, each of which
++enables or disables a particular option group.  If the variable's
++value is set to 'y', then the option group is enabled; if it set to
++anything else, the option group is omitted.  The file
++'option-groups.defaults', at the top of the source tree, establishes
++default values for all variables; all option groups are enabled by
++default.
++
++For example, the following 'option-groups.config' would omit locale
++data, but include mathematical functions, and everything else:
++
++   OPTION_EGLIBC_LOCALES = n
++   OPTION_EGLIBC_LIBM = y
++
++Like the Linux kernel, EGLIBC supports a similar set of '*config' make
++targets to make it easier to create 'option-groups.config', with all
++dependencies between option groups automatically satisfied.  Run
++'make help' to see the list of supported make config targets.  For
++example, 'make menuconfig' will update the current config utilising a
++menu based program.
++
++The option group names and their type (boolean, int, hex, string), help
++description, and dependencies with other option groups, are described by
++'option-groups.def' at the top of the source tree, analogous to the
++'Kconfig' files in the Linux kernel.
++
++In general, each option group variable controls whether a given set of
++object files in EGLIBC is compiled and included in the final
++libraries, or omitted from the build.
++
++Each subdirectory's Makefile categorizes its routines, libraries, and
++executables by option group.  For example, EGLIBC's 'math/Makefile'
++places the 'libm' library in the OPTION_EGLIBC_LIBM group as follows:
++
++   extra-libs-$(OPTION_EGLIBC_LIBM) := libm
++
++Finally, common code in 'Makerules' cites the value of the variable
++'extra-libs-y', selecting only those libraries that belong to enabled
++option groups to be built.
++
++
++Current Status and Future Directions
++
++The EGLIBC component configuration system described here is still
++under development.
++
++We have used the system to subset some portions of EGLIBC's

+When ld-linux-*.so.2 is relocated to a path that is longer than the
+original fixed location, the dynamic loader will crash in open_path
+because it implicitly assumes that max_dirnamelen is a fixed size that
+never changes.
+

+Upstream-Status: Inappropriate [embedded specific]
+
+The native version of ldconfig was using native definition of LD_SO (i.e. 
+ld-linux-x86-64.so.2 ) which is not correct for doing the cross ldconfig.
+This was causing libc.so on the target marked as ELF lib rather than 
+FLAG_ELF_LIBC6 in the ld.so.cache.

Hi Chunrong,

Can you please explain what's going on with PPC and Yocto?  It was just 
a few months back when all PPC was removed from meta-freescale.

https://github.com/Freescale/meta-freescale/commit/86e2ed54cd60da4f9f427baf6dbefbc9911141e6

https://www.mail-archive.com/meta-freescale@yoctoproject.org/msg20572.html

Thank you,

Bob

Re: [PATCH 01/18] e500v2.inc: add recipe

[Zhenhua Luo]

Hi Bob, 

As you know, LSDK (Layerscape SDK) replaced the QSDK (QorIQ PPC, ARM SDK) in last June. In 17.06, 17.09 and 19.09-update releases, ARM targets are integrated continuously, PPC was not supported, to align with the scope of LSDK, we removed the PPC machines from Yocto. In recent LSDK 17.12 release, the PPC support was integrated, accordingly we add back the PPC machines in Yocto. 

Hope the clarification is helpful for your understanding. 


Best Regards, 

Zhenhua
