Hi
This patchset is taken from http://martinwguy.co.uk/martin/crunch/
It is enabled by default for ep93xx devices as EDB9301 boots into rootfs
built with this toolchain without problems. Running "openssl speed"
works but end table with results contains broken calculations.
Binary locales do not work as QEMU do not handle ep93xx cpu.
Patches are a bit ugly maybe (in conf/machine/include/*) but I want to
show it finally to people before it rust.
Text from page:
On 10 March there were no known bugs in this stuff (again). On 19 March
libvorbisenc managed to find a bug in GCC whereby it incorrectly
optimizes certain code sequences that use single-precision floats. The
Maverick code generator exhibits similar symptoms for the same code, but
only at optimization levels -O2 and above, so the fastest reliable
optimization options for Maverick at present are -O -ffast-math.
I've been working on GCC-4.3.3 to make it generate working code for the
Cirrus Logic MaverickCrunch FPU, as found in their ARM-based EP9302,
EP9307, EP9312 and EP9315 chips, making floating point-intensive code
about 2.5 times faster.
This follows on from Hasjim Williams' earlier work with gcc-4.1.2 and
4.2.0, a bundle of his more recent ideas and more hacks from me.
If you want to understand the patches themselves, there is an article
about the MaverickCrunch FPU and GCC's problems with it on the Debian
wiki [1] and I have added commentary at the top of the individual patch
files.

+They are based on the patch ideas for OpenEmbedded that Hasjim Williams sent me
+privately in April 2008, with my own reimplementation of the CCMAV mode and the
+addition of a -mieee switch to fully respect denormalized values (with a 50%
+speed penalty).
+

+These modifications implement a new condition code mode CCMAV which is used
+on floating point comparisons that were performed in the Maverick Crunch FPU.
+
+This is necessary because the Maverick sets the conditions codes differently
+from the ARM/FPA/VFP. Since we do not use the Maverick's 32-bit int modes nor
+its 64-bit comparison, these different conditions pertain to all floating point
+comparisons when compiling for Maverick hardfloat.
+
+ ARM/FPA/VFP - (cmp*): MaverickCrunch - (cfcmp*):
+ N Z C V N Z C V
+ A == B 0 1 1 0 A == B 0 1 0 0
+ A < B 1 0 0 0 A < B 1 0 0 0
+ A > B 0 0 1 0 A > B 1 0 0 1
+ unord 0 0 1 1 unord 0 0 0 0
+
+The new mode is set on floating point comparisons instead of the usual
+CCFP and CCFPE, then acted upon when the conditional instruction flags
+are output.
+
+Furthermore, the list of conditions that cannot be tested with a single
+conditional test is different. On ARM/FPA/VFP it is UNEQ and LTGT while
+on Maverick it is GE UNLT ORDERED and UNORDERED.
+We handle this with a new predicate "maverick_comparison_operator" that omits
+the comparisons that cannot be represented and we split the cond_exec pattern
+into for CCMAV mode plus a separate rule for every non-Maverick CC mode.
+This prevents generation of conditional instructions that cannot be represented.
+
+Although Maverick can also represent LTGT and UNEQ with a single test, we do not
+include these since it would mean splitting every other rule that uses
+"arm_comparison_operator" in a similar way for very little gain.
+
+A few other tests are added to prevent optimisations that would
+generate these unrepresentable conditions.
+
+None of these changes affect code generation for ARM or for other FPUs.
+
+One missed optimisation: movsfcc and movdfcc have been
+disabled for Maverick because we don't use the Maverick's instructions
+conditionally to avoid hardware bugs. But a limited movsfcc and movdfcc
+could be included when Maverick, that applies to all modes where the things
+to be moved do not involve the Maverick registers, if such a thing is feasible
+without the optimizer moving things into registers between the expand and the
+instruction generation.

+This patch disables all 64-bit integer operations of the MaverickCrunch unit
+unless the new flag -mcirrus-di is supplied (as well as -mcpu-ep9312
+-mfpu=maverick -mfloat-abi=softfp).
+
+The 64-bit instructions (or their GCC support) are known to be buggy, as shown
+for example by openssl-0.9.8g's testsuite:
+In the unpacked openssl source directory:
+ $ ./config
+ $ vi Makefile
+ > /^CC= /s/$/-4.3-crunch/
+ > /^CFLAG= /s/$/ -mcpu=ep9312 -mfpu=maverick -mfloat-abi=softfp -mcirrus-di/
+ > :wq
+ $ make
+ $ make test
+fails if either of the two files: */sha/sha512.c and */bn/bn_asm.c are compiled
+with cirrus 64-bit support enabled. If you disable cfmul64, sha512.c works ok,
+but I've disabled everything down to cfadd64, cfsub64 and 64-bit load and store
+and bn_asm still fails, which suggests another hardware timing bug.

+This patch:

+- maps branch-noncirrus-cirrus to branch-noncirrus-nop-cirrus
+- inserts a nop in load rN - load/store64 mvX,[rN] sequences to avoid an
+ undocumented hardware bug.
+- always fixes up invalid code sequences when compiling hard Maverick insns
+ and removes the -mcirrus-fix-invalid-insns flag because chip development
+ has stopped and all existing silicon has these bugs, while the extra code
+ that claimed to do other things for the extra bugs in the old revision D0
+ silicon was complete junk.
+- Takes the cirrus checking out of the main arm_reorg loop, to remove the
+ speed penalty it caused when not compiling for Maverick.

+This patch adds an -mieee flag to GCC for ARM, that only has any effect when
+hard MaverickCrunch FPU code generation is selected.
+It disables the buggy instructions that do not recognise or do not generate
+denormalized values when they should:
+ add, sub, neg, abs and float<->double conversions.
+That leaves only floating point multiplication, comparison, conversions to/from
+integers and the 64-bit integer operations.

+Patch to add description of MaverickCrunch pipelines.
+
+This increases the speed as measured by the fftw benchmark from
+5.4 to 5.8 mflops and reduced LAME's execution time from 2m30 to 2m20.
+
+I don't know who wrote this - I got it from Hasjim Williams.

++Cirrus Logic MaverickCrunch FPU support
++=======================================
++
++The MaverickCrunch is an FPU coprocessor that only exists in combination
++with an arm920t (ARMv4t arch) integer core in the 200MHz EP93xx devices.
++Code generation for it is usually selected with
++ -mcpu=ep9312 -mfpu=maverick (and most likely -mfloat-abi=softfp)
++
++Within GCC, the names "cirrus" "maverick" and "crunch" are used randomly
++in filenames and identifiers, but they all refer to the same thing.
++
++Initial support was mainlined by RedHat in gcc-3 but this never generated
++working code. Cirrus Logic funded the company Nucleusys to produce a modified
++GCC for it, but this never worked either. The first set of patches to pass
++the testsuite were made by Hasjim Williams for Open Embedded, though they
++did this by disabling various features and optimisations, therby incurring
++a small negative impact on regular ARM code generation.
++The OE ideas were reimplemented by Martin Guy to produce a working compiler
++with no negwative impact on regular code generation.
++
++The FPU's characteristics
++-------------------------
++Like most ARM coprocessors, it runs in parallel with the ARM though its
++instructions are inserted into the regular ARM instructions stream.
++It has 16 64-bit registers that can be operated as 32-bit or 64-bit integers
++or as 32-bit or 64-bit floats, three 72-bit saturating multiplier-accumulators.
++It can add, sub, mul, cmp, abs and neg these types, convert between them and
++transfer values between its registers and the ARM registers or main memory.
++
++Comparisons performed in the Maverick unit set the condition codes differently
++from the ARM/FPA/VFP instructions:
++
++ ARM/FPA/VFP - (cmp*): MaverickCrunch - (cfcmp*):
++ N Z C V N Z C V
++ A == B 0 1 1 0 A == B 0 1 0 0
++ A < B 1 0 0 0 A < B 1 0 0 0
++ A > B 0 0 1 0 A > B 1 0 0 1
++ unord 0 0 1 1 unord 0 0 0 0
++
++which means that the same conditions have to be tested for with different ARM
++conditions after a Maverick comparison. Furthermore, some conditions cannot
++be tested with a single condition.
++This was already true on ARM/FPA/VFP for conditions UNEQ and LTGT;
++on Maverick comparisons it is GE UNLT ORDERED and UNORDERED that cannot.
++(GE after a floating point comparison, that is, not after an integer comarison)
++
++GCC's use of the Maverick unit
++------------------------------
++GCC only uses the 32-bit and 64-bit floating point modes and the 64-bit
++integer mode. It does not use the 72-bit accumulators or the 32-bit integer
++mode because, from "GCC Machine Descriptions":
++ "It is obligatory to support floating point `movm' instructions
++ into and out of any registers that can hold fixed point values,
++ because unions and structures (which have modes SImode or DImode)
++ can be in those registers and they may have floating point members."
++(search also for "grief" in arm.c).
++
++It does not use the 64-bit integer comparison instruction because it can only
++do a signed or an unsigned comparison, while GCC expect the comparison to set
++the conditions codes for both modes and then to use the signed or unsigned
++mode when the condition code bits are tested.
++
++The different setting of the condition codes is tracked with an additional
++CCMAV mode for the condition code register, set when a comparison is performed
++in the Maverick unit. This always indicates a floating point comparison since
++the Maverick's 64-bit comparison is not used.
++
++Hardware bugs and workarounds
++-----------------------------
++All silicon implementations of the FPU have a dozen hardware bugs, mostly
++timing-dependent bugs that can write garbage into registers or memory or get
++conditional tests wrong, as well as a widespread failure to respect
++denormalised values. See http://wiki.debian.org/ArmEabiMaverickCrunch
++
++There used to be a -mcirrus-fix-invalid-instructions flag that claimed
++to avoid bugs in revision D0 silicon but its code was broken junk.
++Currently GCC always avoids the timing bugs in revision D1 to E2 silicon,
++while the many extra timing bugs in the now rare revision D0 are not handled.
++
++By default, the instructions that drop denoermalized values are enabled
++so as to obtain maximum speed at lower precision. By default, the cfnegs
++and cfnegd instrutions are disabled, since they also fail to produce negative
++zero. They can be enabled with -fno-signed-zeros.
++
++When -mfpu=maverick is selected, an additional -mieee flag is active that
++gives full IEEE precision by performs all the non-denorm-respecting
++floating point instructions in the softfloat library routines or in the
++integer registers.
++
++The 64-bit integer support is still buggy so it is disabled unless the
++-mcirrus-di flag is supplied. As well as the having unidentified
++hardware bugs which make openssl's testsuite fail in */sha/sha512.c and in
++*/bn/bn_adm.c, 64-bit shifts only work up to 31 places left or 32 right.
++
++Other bugs
++----------
++There seems to be no way to configure GCC to select Maverick code generation
++as the default.
++
++--with-arch=ep9312 the assembler barfs saying that ep9312 is not a
++recognised architecture.
++--with-arch=armv4t the build fails when it tries to compile hard FPA
++instructions into libgcc,
++--with-cpu=ep9312 it compiles armv5t instructions into libgcc

Here I am with another set of patches to make EP93xx cpus working better
in OpenEmbedded.
This time I merged glibc 2.6.1 and binutils 2.18 patches done by Hasjim
Williams and changed a bit Ångström configs for building with Maverick
tuning enabled.
After rebuilding whole rootfs I got system which works and even gives
proper output from 'openssl speed md5' command.
