Ah... When I solved the huge conflict this morning due to AVX10 refactor for
GCC13/12, I forgot that it is in GCC14 AVX10.1 refactor when I added the
_mm_avx512_setzero_ps/pd. Should use _mm_setzero_ps/pd instead.
Never do something tweak quickly on a sleepy Monday morning.

Ping for this thread.
Any ideas? If no, I will change the generated info with command following
if we take r15-1643 as example and see if it is clearer:
head -26 makelog.r15-1643.x86_64.native | tail -7 > 1.log;
grep -E "(error:|Error)" makelog.r15-1643.x86_64.native >> 1.log;

The three avx10.2 related test regression are all related to the usage of
-mavx10.2 -march=cascadelake, which is unavoidable warning.
I am considering to change -march=cascadelake to a arch with AVX10 in
the future to avoid these false alarms.

As applied to all AVX10.2 patches, it is caused by vector size warning
mentioned previously.

As each AVX10.2 testcases previously, this is caused by option combination
warning,
which is expected.

Hi Matthias,
From my side, I get several error like this:
/export/users/haochenj/src/gcc-bisect/master/master/r15-429/bld/x86_64-linux/32/libstdc++-v3/include/experimental/bits/simd_builtin.h:131:

wrong code with points-to and volatile

The fail is expected since -march=cascadelake -mavx10.1-256 will lead to a
warning.
Also, we could not use -mno-avx512f with -mavx10.1-256, which also lead to a
warning.

Hi Paul,
I suspect it is not the correct way to do that, those lines are ok since they
are XFAIL. The problem is that specific warning test.

Just did a quick test. Correct myself previously. Those lines also
needs to be removed since they are XPASS now.
However the real issue is the dg-note at Line 32, that is the warning
disappeared.
diff --git a/libgomp/testsuite/libgomp.oacc-fortran/privatized-ref-2.f90
b/libgomp/testsuite/libgomp
It might be a false positive timeout alert. Please ignore that first.

Hi all,
During my vacation last three weeks, it seems to me that
my bisect script is down. After I am back from my holiday
this week, I found that the machine OS disk is totally down.
Please expect some time to bring that bisect script back. The
Test regression reporter is still running. (However
The script is back online for now. But still with some issues
on automation due to the machine config after crash.
I will run the script on at least a daily basis for a temporary
solution.
Thx,
