Hi, Ian
I believe that this patch broke bootstrap on AIX:

Hi, David
Unfortunately r15-636-g770657d02c986c causes a bootstrap failure on AIX
when building f951 in stage2. cc1 and cc1plus link successfully. There
doesn't seem to be a similar failure for powerpc64-linux BE or LE.
The failure is

Why aren't these patches being tested on all major architectures,
especially those available in the Compile Farm? At least for correctness,
if not performance.
Thanks, David

aix: Fix building fat library for AIX
With the change in subdirectories, the code for libgfortran fat
libraries
needs to be adjusted to explicitly reference the subdirectory. AIX
creates fat library archives and the compiler itself can be built as
either 32 bit or 64 bit appli
The patch does not cause failures on AIX. Is it removing explicit
references to /lib and /usr/lib?
It seems more appropriate for GCC 15.
Thanks for alerting me to the patch to test on AIX. AIX is in CFarm.
Thanks David

If the fixes remove the failures on AIX, then the patch to disable the
tests also can be reverted.

Also, the AWK portions are common code, not RISC-V specific. I don't see

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.
Tha
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,

Hi, Andrew
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
am building as 32 bit, so this could be a specific issue about bit siz

This patch has broken GCC bootstrap on AIX. It appears to rely upon, or
complain about, the command "seq":
/nasfarm/edelsohn/install/GCC12/bin/g++ -std=c++11 -g -DIN_GCC
-fno-exceptions -fno-rtti -fasynchronous-unwind-tables -W -Wall
-Wno-narrowing -Wwrite-strings -Wcast-qual -Wno-format

Hi, Gerald
That change is fine with me.
Thanks, Da
This patch broke bootstrap on AIX due to its use of strchrnul(). It is an
extension available in Linux, but not all targets.
/src/src/gcc/cp/contracts.cc:213:21: error: 'strchrnul' was not declared in
this scope; did you mean 'strchr'?
213 | size_t role_len = strchrnul (role, ':') - role;

There are Power (rs6000) systems in the Compile Farm.
Trial Linux on Z (s390x) VMs are available through the Linux Commu
This patch seems to have broken bootstrap on AIX. It seems to assume
methods that aren't guaranteed to be defined.
Thanks, David

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
bootstrap on AIX. It seems rather bad policy to remove support for a
feature without ensuring that the removal does not negatively impact the
targets touched by the patch. I should have been explicitly copied on
these patches
