For clarification: I did not bisect, but yesterdays build did work,
today's doesn't, and I am seeing warnings while building libgfortran
most likely pointing to this change.

It is weird since everything passed even under bootstrap.
Could you provide the exact options you build GCC with --disable-bootstrap for
me to reproduce?
I suppose all of them are '--enable-libsanitizer' '--disable-bootstrap'
'--enable-valgrind-annotations' '--with-system-zlib' '--prefix=/opt/gcc/14'
'CC=/usr/bin/gcc-13' 'CFLAGS=-g -O2 -march=native' 'CXX=/usr/bin/g++-13'

I suspect the common theme here is enable-default-pie .
In the case of the original report was built with a compiler that had enabled
and --disable-bootstrap got it.

I added --enable-default-pie into config and it still won't reproduce the fail.
I am suspecting whether it is caused by the GCC version which compiles GCC.

Wait -march=native .
Are these all on cores that have avx on it? If this is a dup of that other bug.

It might be that the issue has been latent for a long time and only started to
show up with newer sources and that bootstrap actually is the only way to
workaround it now (well when it is fixed).

Intel(R) Core(TM) i5-8250U and AMD Ryzen 7 PRO 6850U both have AVX.
I am trying to reproduce that on building trunk with GCC 13.

Ok, I am able to reproduce the issue now.
Simple testcase:
```
#include <x86intrin.h>
```
And then compile with `-march=native` and you will see the failure.

`-march=native` will add `-mno-avx10.1-256` to the command line and that causes
the failure.

This is a known issue I figured out yesterday but should not cause the problem
since it actually relaxed conditions. It will cause ICE when caliing builtins
directly.
The reason why I am not reproducing the regression seems mainly caused by the
machine I built with all have AVX512, but all the CPUs mentioned here did not,
which will lead to different behavior on march and option override.
Rebuilding on AVX only machine to reproduce.

A quick workaround would be not appending -mno-avx10.1-xxx into -march=native.
And it should work after my experiment. However, I am finding a better way to
do that.
The real problem seems like the AVX10 and AVX512 options handling in override
part messed up flags while both explicit no on options and finally messed up
the pragma push in avx512vp2intersect since it is the only AVX512 ISA out of
AVX10.1 except for Xeon Phi.
