Hi, Arsen
This patch broke bootstrap because it has introduced a new GCC build
requirement for autogen that is not a previous requirement to build GCC.
Previously the repository has included post-processed files.

FOSS Best Practices recommends that projects have an official Security
policy stated in a SECURITY.md or SECURITY.txt file at the root of the
repository. GLIBC and Binutils have added such documents.

Binutils document because
Hi, Drew
Thanks for addressing this missed optimization.
The testcase includes an incorrect assumption: signed char, which
causes the testcase to fail on PowerPC.
Should the testcase be updated to specify signed char in the function
signatures or should -fsigned-char be added to the command line

Hi, Jiufu
This definitely seems to be a better solution.
The TARGET_CONST_ANCHOR change should not be part of this patch. Also
there is no ChangeLog for the patch.
This generally looks correct and consistent with other ports. I want
to give Segher a chance to double check it, if he wishes.

The rs6000 port has allocated a stack frame when debugging is enabled
on AIX since the earliest versions of the port. Apparently the
earliest versions of the debuggers for AIX had difficulty with
stackless frames.
Both AIX DBX and GDB support stackless frames on AIX, and IBM XLC,

Thanks for this series of patches to improve do_store_flag. Unfortunately
this specific patch in the series has caused a bootstrap failure on
powerpc-aix. I bisected this failure to this specific patch. Note that I

cbranchcc4 is a named pattern and requires a specific operand ordering. If
you change *cbranch to cbranchcc4, you must change the order of the
operands, not a quick and dirty hack to *cbranch. Also, you should change
*cbranch_2insn and *creturn as well so that all of the patterns are

This patch causes a bootstrap comparison failure on AIX. It apparently
does not cause a failure on PPC64BE Linux with the same ABI, so I suspect
that the failure may be related to the way that function aliases are
implemented on AIX, which doesn't have ELF symbol alias semantics.

I fully support the plan to remove stabs support, but this patch broke

are sending the patch from the FreeBSD organization, but I don't know
the authority structure within the organization. Andreas Tobler is

This series of patches has exploded memory usage and I can no longer

As with the Ranger problem exposed by Aldy's patch last September,
something is not freeing memory.

No attempt is made to optimize writing the FPSCR (by checking if the new
value would be the same), other than using lighter wei

Siddhesh,
This patch series seems to have caused testsuite regressions for
memcpy-chk, etc. in 32 bit mode (i386, x86-64 -m32 and -mx32, AIX 32

I have opened PR 103759.
Thanks, David
