Second attempt. Added some more patches, mostly ARM specific.
AFAIK this patchset passed all x86-64 tests.
I also did some limited testing with meta-raspberrypi and musl library.
(raspberrypi did not build with v1 of the patchset)

To: openembedded-core; +Cc: jurobystricky
Changed BINV and PV from 6.2.0 to 6.4.0
Modified BASEURI to load xz tarball instead of bz2
The upgrade to 6.4 includes all of the gcc 6.x changes from OE-Core master from
various authors to bring the various releases into sync and ensure all relavent
fixes are present.
Backported series of patches from https://github.com/hjl-tools/gcc.git
branch /hjl/indirect/gcc-6-branch/master which contains
an IA patch series for security related issues
Backported/added several patches to address various ARM and musl build issues:
0001-enable-FL_LPAE-flag-for-armv7ve-cores.patch
0048-sync-gcc-stddef.h-with-musl.patch
0054_all_nopie-all-flags.patch
0055-unwind_h-glibc26.patch
0057-ARM-PR-82445-suppress-32-bit-aligned-ldrd-strd-peeph.patch
ubsan-fix-check-empty-string.patch : removed, already applied
0048-ARM-PR-target-71056-Don-t-use-vectorized-builtins-wh.patch: removed, already upstreamed
CVE-2016-4490.patch: removed, already upstreamed
Added CVE-2016-6131.patch
Moved all backported patches into a separate folder "backport", as it
is common for other gcc recipes.

+Backport and edit of patches from:
+https://gcc.gnu.org/viewcvs/gcc?limit_changes=0&view=revision&revision=249957
+by jsm28 (Joseph Myers)
+
+Current glibc no longer gives the ucontext_t type the tag struct
+ucontext, to conform with POSIX namespace rules. This requires
+various linux-unwind.h files in libgcc, that were previously using
+struct ucontext, to be fixed to use ucontext_t instead. This is
+similar to the removal of the struct siginfo tag from siginfo_t some
+years ago.
+
+This patch changes those files to use ucontext_t instead. As the
+standard name that should be unconditionally safe, so this is not
+restricted to architectures supported by glibc, or conditioned on the
+glibc version.

+Subject: [PATCH] [ARM] PR 82445 - suppress 32-bit aligned ldrd/strd peepholing
+ with -mno-unaligned-access
+
+Peephole patterns exist in the arm backend to spot load/store
+operations to adjacent memory operations in order to convert them into
+ldrd/strd instructions. However, when we have strict alignment
+enforced, then we can only do this if the accesses are known to be
+64-bit aligned; this is unlikely to be the case for most loads. The
+patch adds some alignment checking to the code that validates the
+addresses for use in the peephole patterns. This should also fix
+incorrect generation of ldrd/strd with unaligned accesses that could
+previously have occurred on ARMv5e where all such operations must be
+64-bit aligned.
+
+I've added some new tests as well. In doing so I discovered that the
+ldrd/strd peephole tests could never fail since they would match the
+source file name in the scanned assembly as well as any instructions
+of the intended type. I've fixed those by tightening the scan results
+slightly.
+
+gcc:
+
+* config/arm/arm.c (align_ok_ldrd_strd): New function.
+(mem_ok_for_ldrd_strd): New parameter align. Extract the alignment of the
+mem into it.
+(gen_operands_ldrd_strd): Validate the alignment of the accesses.
+
+testsuite:
+
+* gcc.target/arm/peep-ldrd-1.c: Tighten test scan pattern.
+* gcc.target/arm/peep-strd-1.c: Likewise.
+* gcc.target/arm/peep-ldrd-2.c: New test.
+* gcc.target/arm/peep-strd-2.c: New test.

+Subject: [PATCH] enable FL_LPAE flag for armv7ve cores
+
+The following commit added the FL_LPAE flag to FL_FOR_ARCH7VE, but
+neglected to also add it to the armv7ve compatible cores defined in
+arm-cores.def.
+
+ https://github.com/gcc-mirror/gcc/commit/af2d9b9e58e8be576c53d94f30c48c68146b0c98
+
+The result is that gcc 6.4 now refuses to allow -march=armv7ve and
+-mcpu=XXX to be used together, even when -mcpu is set to an armv7ve
+compatible core:
+
+ arm-linux-gnueabi-gcc -march=armv7ve -mcpu=cortex-a7 -Werror ...
+ error: switch -mcpu=cortex-a7 conflicts with -march=armv7ve switch [-Werror]
+
+Fix by defining flags for armv7ve compatible cores directly from
+FL_FOR_ARCH7VE, rather than re-creating the armv7ve flags
+independently by combining FL_FOR_ARCH7A with the armv7ve specific
+FL_THUMB_DIV and FL_ARM_DIV flags.

+
+We can use const reference of struct ix86_frame to avoid making a local
+copy of ix86_frame. ix86_expand_epilogue makes a local copy of struct
+ix86_frame and uses the reg_save_offset field as a local variable. This
+patch uses a separate local variable for reg_save_offset.
+
+Tested on x86-64 with ada.

+Subject: [PATCH 04/12] x86: Add -mindirect-branch=
+
+Add -mindirect-branch= option to convert indirect call and jump to call
+and return thunks. The default is 'keep', which keeps indirect call and
+jump unmodified. 'thunk' converts indirect call and jump to call and
+return thunk. 'thunk-inline' converts indirect call and jump to inlined
+call and return thunk. 'thunk-extern' converts indirect call and jump to
+external call and return thunk provided in a separate object file. You
+can control this behavior for a specific function by using the function
+attribute indirect_branch.
+
+2 kinds of thunks are geneated. Memory thunk where the function address
+is at the top of the stack:
+
+__x86_indirect_thunk:
+ call L2
+L1:
+ pause
+ lfence
+ jmp L1
+L2:
+ lea 8(%rsp), %rsp|lea 4(%esp), %esp
+ ret
+
+Indirect jmp via memory, "jmp mem", is converted to
+
+ push memory
+ jmp __x86_indirect_thunk
+
+Indirect call via memory, "call mem", is converted to
+
+ jmp L2
+L1:
+ push [mem]
+ jmp __x86_indirect_thunk
+L2:
+ call L1
+
+Register thunk where the function address is in a register, reg:
+
+__x86_indirect_thunk_reg:
+ call L2
+L1:
+ pause
+ lfence
+ jmp L1
+L2:
+ movq %reg, (%rsp)|movl %reg, (%esp)
+ ret
+
+where reg is one of (r|e)ax, (r|e)dx, (r|e)cx, (r|e)bx, (r|e)si, (r|e)di,
+(r|e)bp, r8, r9, r10, r11, r12, r13, r14 and r15.

+Subject: [PATCH 05/12] x86: Add -mfunction-return=
+
+Add -mfunction-return= option to convert function return to call and
+return thunks. The default is 'keep', which keeps function return
+unmodified. 'thunk' converts function return to call and return thunk.
+'thunk-inline' converts function return to inlined call and return thunk.
+'thunk-extern' converts function return to external call and return
+thunk provided in a separate object file. You can control this behavior
+for a specific function by using the function attribute function_return.
+
+Function return thunk is the same as memory thunk for -mindirect-branch=
+where the return address is at the top of the stack:
+
+__x86_return_thunk:
+ call L2
+L1:
+ pause
+ lfence
+ jmp L1
+L2:
+ lea 8(%rsp), %rsp|lea 4(%esp), %esp
+ ret
+
+and function return becomes
+
+ jmp __x86_return_thunk
+
+-mindirect-branch= tests are updated with -mfunction-return=keep to
+avoid false test failures when -mfunction-return=thunk is added to
+RUNTESTFLAGS for "make check".

+Subject: [PATCH 06/12] x86: Add -mindirect-branch-register
+
+Add -mindirect-branch-register to force indirect branch via register.
+This is implemented by disabling patterns of indirect branch via memory,
+similar to TARGET_X32.
+
+-mindirect-branch= and -mfunction-return= tests are updated with
+-mno-indirect-branch-register to avoid false test failures when
+-mindirect-branch-register is added to RUNTESTFLAGS for "make check".

+Subject: [PATCH 08/12] x86: Disallow -mindirect-branch=/-mfunction-return=
+ with -mcmodel=large
+
+Since the thunk function may not be reachable in large code model,
+-mcmodel=large is incompatible with -mindirect-branch=thunk,
+-mindirect-branch=thunk-extern, -mfunction-return=thunk and
+-mfunction-return=thunk-extern. Issue an error when they are used with
+-mcmodel=large.

+Subject: [PATCH 11/12] i386: Update -mfunction-return= for return with pop
+
+When -mfunction-return= is used, simple_return_pop_internal should pop
+return address into ECX register, adjust stack by bytes to pop from stack
+and jump to the return thunk via ECX register.
+
+Revision 257992 removed the bool argument from ix86_output_indirect_jmp.
+Update comments to reflect it.
+
+Tested on i686 and x86-64.

+
+x86-64 is supposed to have asynchronous unwind tables by default, but
+there is nothing that reflects the change in the (relative) frame
+address after .LIND0. That region really has to be moved outside of
+the .cfi_startproc/.cfi_endproc bracket.
+
+This patch adds TARGET_INDIRECT_BRANCH_REGISTER to force indirect
+branch via register whenever -mindirect-branch= is used. Now,
+-mindirect-branch=thunk-extern -O2 on x86-64 GNU/Linux generates:
+
+_Z1fP1C:
+.LFB0:
+ .cfi_startproc
+ pushq %rbx
+ .cfi_def_cfa_offset 16
+ .cfi_offset 3, -16
+ movq (%rdi), %rax
+ movq %rdi, %rbx
+ movq 16(%rax), %rax
+ call __x86_indirect_thunk_rax
+ movq (%rbx), %rax
+ movq %rbx, %rdi
+ popq %rbx
+ .cfi_def_cfa_offset 8
+ movq 16(%rax), %rax
+ jmp __x86_indirect_thunk_rax
+ .cfi_endproc
+
+so that "-mindirect-branch=thunk-extern" is equivalent to
+"-mindirect-branch=thunk-extern -mindirect-branch-register", which is
+used by Linux kernel.

+Subject: [PATCH] [ARM] PR 82445 - suppress 32-bit aligned ldrd/strd peepholing
+ with -mno-unaligned-access
+
+Peephole patterns exist in the arm backend to spot load/store
+operations to adjacent memory operations in order to convert them into
+ldrd/strd instructions. However, when we have strict alignment
+enforced, then we can only do this if the accesses are known to be
+64-bit aligned; this is unlikely to be the case for most loads. The
+patch adds some alignment checking to the code that validates the
+addresses for use in the peephole patterns. This should also fix
+incorrect generation of ldrd/strd with unaligned accesses that could
+previously have occurred on ARMv5e where all such operations must be
+64-bit aligned.
+
+I've added some new tests as well. In doing so I discovered that the
+ldrd/strd peephole tests could never fail since they would match the
+source file name in the scanned assembly as well as any instructions
+of the intended type. I've fixed those by tightening the scan results
+slightly.
+
+gcc:
+
+* config/arm/arm.c (align_ok_ldrd_strd): New function.
+(mem_ok_for_ldrd_strd): New parameter align. Extract the alignment of the
+mem into it.
+(gen_operands_ldrd_strd): Validate the alignment of the accesses.
+
+testsuite:
+
+* gcc.target/arm/peep-ldrd-1.c: Tighten test scan pattern.
+* gcc.target/arm/peep-strd-1.c: Likewise.
+* gcc.target/arm/peep-ldrd-2.c: New test.
+* gcc.target/arm/peep-strd-2.c: New test.

I forgot to mention that if there are no objections against this patchset, I intend to do the same/equivalent upgrades for other releases with gcc 6x (rocko, pyro, ...) and also upgrade gcc5.x and 4.9x where present.

Subject: [morty][PATCH v2] gcc6.4 upgrade
Second attempt. Added some more patches, mostly ARM specific.
AFAIK this patchset passed all x86-64 tests.
I also did some limited testing with meta-raspberrypi and musl library.
(raspberrypi did not build with v1 of the patchset)

This was morty upgrade, which did not have those patches to begin with, I did not remove them. The patches were not in rocko either, in the end I got them from master (gcc6.4 was eventually removed completely),
Backporting of ARM specific patches was not the objective. ( I was not aware that 6.4 had an ARM specific regression which broke the pi3 builds).
Long story short, all patches should be there now, please review them, see the commit message for more details.
I'll make sure all other gcc6 upgrades contain the ARM patches as well.

Comparing my morty branch (with update to gcc 6.4 by backporting
incremental gcc updates from master) and today's morty-next (which
updates gcc 6.2 -> 6.4 with a single commit) the only differences are:
- My branch lacks all the new x86 specific patches (OK, since they
are appearing here first)
- Today's morty-next is lacking one patch, which was added to oe-core
master as a backport (from gcc master) to gcc 6.3:
http://git.openembedded.org/openembedded-core/commit/?id=d2631f45a057c53797b7ba657662f35f66a2b04e
I don't have any strong opinions on the patch, but presumably it fixed
some issue Khem was seeing, it still applies cleanly to gcc 6.4 and we
have it in rocko so on balance I'd say it should probably be in morty
too.
Overall this looks great though and I'm very happy to see gcc updates
landing in the release branches. Thanks Juro!

The v2 patch was sent to the list here:
http://lists.openembedded.org/pipermail/openembedded-core/2017-November/144159.html
but it seems my morty branch still has the v1 patch with the typo...

Thanks for this work.
It might be a bit easier to do and review this by starting with rocko
(with just small change on top with newly backported changes) and just
cherry-picking the necessary changes down to pyro and then few more down
to morty (similar to Andre's backports in his branch).
With single big patch it's difficult to make sure that all the branches
got all the changes and to review what's "new" compared to 6.4.0 which
used to be in master.

I do agree with you that in an ideal world, this is how it should be
done.
I also realise part of the problem here is a few different companies
have patched gcc 6.x in older releases and not submitted the changes
with upstream stable. I appreciate there could be a ton of different
reasons for that. It would be nice to try and share this work earlier
and more often to avoid having patchsets quite this large.
It is tough to have someone step up and try and make changes to gcc in
OE-Core since the test matrix is quite large and fixing all the issues
that can come up is non-trivial.
I'm therefore very grateful for Juro taking this on and I don't
particularly want to have him go back and redo the patches again,
particularly for feedback at v2.
I've been doing my best to guide Juro, equally I'm trying to do a
number of things at the moment (M3 still isn't ready and the
autobuilder is a wreak) and I clearly haven't given Juro enough
guidance to get this 'right'. For that I do feel bad.
So now I have a horrible choice. Do I push this back to Juro and have
him do this again as you comment. I know I'll have to provide mode
guidance, I'm travelling and its hard on everyone. Do I feel guilty for
my part in this and sort the splitting up myself to avoid impacting
Juro (with the impact on my time/sanity that entails)? Or do I take the
patch and risk upsetting some of our key contributors for ignoring
review?
I'm spelling out the issues here because as a community/team, we need
to get better at guiding people through things like this. It does have
an impact on whether people step up in the first place and may be part
of the reason nobody wants to touch gcc in the first place...
Cheers,
Richard

________________________________
- Today's morty-next is lacking one patch, which was added to oe-core
master as a backport (from gcc master) to gcc 6.3:
http://git.openembedded.org/openembedded-core/commit/?id=d2631f45a057c53797b7ba657662f35f66a2b04e
I don't have any strong opinions on the patch, but presumably it fixed
some issue Khem was seeing, it still applies cleanly to gcc 6.4 and we
have it in rocko so on balance I'd say it should probably be in morty
too.
Yes this patch fixes an arm regression
I actually had to remove this patch,as it caused an ICE compiling valgrind for x86-64. I will retest this patch with other distros to see if it is morty specific.

Feel free to ignore my feedback.
I didn't mean it as strong objection to get this merged as-is.
It was rather an advice for next time or in case another version is sent
(e.g. with that missing patch from Khem) and Juro decides to rework it in
order to save himself some time later when preparing the changes for pyro
and rocko (as he said in the e-mail that he plans to prepare). It shouldn't
be too difficult to rework anyway, because Andre already has the
cherry-picks for morty and Juro can do just rebase of his change on top of
that to get those new patches in separate commit.

If you and/or Juro want, I can do the rebase and send the cherry-picks for
all 3 release branches.

Juro's mail reply was a bit messed up with formatting but that missing
arm patch appeared to cause an internal compiler error when compiling
valgrind for x86-64 and I suspect that is why its missing. If we do
want to consider that one I'd probably make it a separate issue.
I can't really merge anything due to our backports policy until we have
at least the pyro patches sorted. I'm still torn on which way to go but
if someone can pull together a good set of patches for the various
branches I would take it. I'm also pretty sure Juro will be fine if
someone wants to break that patch up.
Cheers,
Richard

If you need a starting point, my patches to backport gcc 6.4 into pyro
are in the "oe23b" branch of
https://github.com/lgirdk/openembedded-core.git
It should be easy to port Juro's new x86 specific patches on top.
The patches to update rocko to gcc 6.4 are in the "oe24b" branch.

I've sent the pull requests for all 3 release branches.
I'll let some builders doing more tests over night, but it's very close to
what was merged in master (and also to what is currently in morty-next) so
it should be relatively safe.
The "significant" diffs between gcc-6.4 in various branches:
1) 84d6be8ceb14b418b059212108c5a71a5950e6c3 (last master commits before 6.4
was removed)
master doesn't
have 0041-Add-ssp_nonshared-to-link-commandline-for-musl-targe.patch which
were backported to rocko from gcc-7.1 later
and it doesn't have new backports from Juro
and 0001-enable-FL_LPAE-flag-for-armv7ve-cores.patc fix from Andre

Heh, I made the same mistake, I did remember that you sent some e-mail that
there was v2 on the ML.
So to be sure I've cherry-picked this one from your branch instead of
cherry-picking from patchwork which already had your change included 2 more
times in various pull requests from Khem:
https://patchwork.openembedded.org/project/oe-core/patches/?submitter=&state=&q=LPAE&archive=&delegate=
so instead of checking which version was the correct one, I've
cherry-picked it from your branch..
.. and only after the patchtest complained again, I've read the 2nd half of
your message saying that your morty branch has v1 :).

Thanks for this. I've staged the patches in the various -next branches.
I ran pyro-next on the autobuilder to see where we stand and x86-64 is
showing the ICE I mentioned in valgrind so we'll likely need to pull
out that patch until we can figure out a way of fixing that. I'll queue
a fixup patch and retry and confirm that does fix the issue.
Cheers,
Richard
