           Product: gcc
           Version: 14.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3

          Assignee: unassigned at gcc dot gnu.org
          Reporter: slyfox at gcc dot gnu.org
  Target Milestone: ---

Observed build failure on today's gcc from r14-3296-gdc48d1d1d44587 against
highway-1.0.6 ( https://github.com/google/highway ).

I have not managed to extract nice example ot of it yet, but maybe it's obvious
to you?

The (somewhat big) reproducer is:

$ git clone https://github.com/google/highway
$ cd highway
$ mkdir b
$ cd b

$ make

I have a suspiction it's related to AVX10 changes, like
r14-3268-g0b20e0f17b47a8  which remove `#pragma GCC
target("avx512vl,avx512dq")`. Probably not that one specifically though.

--- Comment #1 from Sergei Trofimovich <slyfox at gcc dot gnu.org> ---
Found this difference, looks reasonable?

// $ cat a.cc
#include <immintrin.h>

#pragma GCC target("avx512vl,avx512dq")

void bug(__m256i i) {
   volatile auto v1 = _mm256_cvtepi64_pd(i);
}

Difference:

$ g++-13 -c a.cc
# ok

$ g++-14 -c a.cc

--- Comment #2 from Haochen Jiang <haochen.jiang at intel dot com> ---
It is caused by when including immintrin.h, since the pragma is removed, there
will be no AVX support, which makes _mm256_setzero_pd invisible.

Adding a AVX2 pragma instead of removing it should solve the problem.

I am working a patch on that.
