Haha.  I had just pulled the fix for this out of our internal tree and was
working to get it upstreamed yesterday.  So it's already fixed on the trunk,
but I didn't have a testcase to add to the suite...  I'll (of course) put your
test into the testsuite.

Same error results when trying to build it manually with the same options that
MacPorts uses. When building manually on Snow Leopard I usually hack around it
with a patch like this:

Fix for the problem

This was part of the patch for #82375, which was a PDT problem.

Please note the comment. I will now have to understand why this nullifying of
'tmp' is necessary. I couldn't see it last time.

The difference is that 'rt' is freed twice in 6- and 7-branches and only once
in 8-branch. I remember effecting a patch to do this. I just need to remind
myself which one it was.

Fix PR82768

Forcing LR at the bottom of the frame caused a few test failures.
Since there are some cases that generate worse code, revert this
part, and the frame tests pass again.

  ac = a * c;

[Bug tree-optimization/80925] [8 Regression] vect peeling failures

(In reply to Richard Biener from comment #26)
> Fixed?

I see still these vect failures on aarch64:

FAIL: gcc.dg/vect/pr65947-14.c execution test
FAIL: gcc.dg/vect/pr65947-14.c -flto -ffat-lto-objects execution test

FAIL: g++.dg/vect/slp-pr56812.cc  -std=c++98  scan-tree-dump-times slp1 "basic

I don't think the pr65947-14.c failure is related to this change but the
pr56812.cc failure is one of the failures listed in the original report.

Fixed from 7.2 onwards - I've verified the failing cases now work. Backporting
to earlier versions seems too risky so close as fixed (generated code is
correct in all cases).

Log:
PR60580: Fix frame pointer option magic

To fix PR60580 simplify the logic in aarch64_override_options_after_change_1
(). 
If the frame pointer is enabled, set it to a special value that behaves similar
to frame pointer omission.  If we don't do this all leaf functions will get a
frame pointer even if flag_omit_leaf_frame_pointer is set.

If flag_omit_frame_pointer has this special value, we must force the frame
pointer if not in a leaf function.  We also need to force it in a leaf function
if flag_omit_frame_pointer is not set or if LR is used.

Doing this allows both -fomit-frame-pointer and -fomit-leaf-frame-pointer to be
independently set and changed in each function with the expected behaviour.

gcc/
PR middle-end/60580
* config/aarch64/aarch64.c (aarch64_frame_pointer_required)
Check special value of flag_omit_frame_pointer.
(aarch64_can_eliminate): Likewise.

-fomit-frame-pointer and -fomit-leaf-frame-pointer.

Since the import of libsanitizer from upstream r315899, many tests FAIL on

+#endif // SANITIZER_SUPPORTS_WEAK_HOOKS

The tests work e.g. on macOS 10.13/Darwin 17.

Since the import of libsanitizer from upstream r315899, it fails to build on

I've found that VM_MEMORY_OS_ALLOC_ONCE is defined in 
since Mac OS X 10.9/Darwin 13.  Wrapping the affected section of code as in the
attached patch allows the build to finish.

Given that I've never had any success getting even the most trivial patches
upstream and have no idea which Darwin versions are supported there, I'm
reporting this here.
