Interesting: /tmp/php/ext/mbstring/mbstring.c:5181:14: warning: implicit declaration of function ‘_mm256_set_m128i’; did you mean ‘_mm256_set_epi8’?

Apparently you are building PHP for a host which supports AVX/AVX2, and your compiler knows about _mm256_set_epi8 (which is an intrinsic function for AVX) but doesn't know about _mm256_set_m128i (which is also an intrinsic function for AVX).

References for these functions:

https://www.intel.com/content/www/us/en/docs/intrinsics-guide/index.html#text=mm256_set_epi8&ig_expand=5847,5842

The prototypes for both of these functions are in immintrin.h.

@GrahamCampbell Could you let me know what C compiler is used on this host?

https://stackoverflow.com/a/32630658/1320374 This is an older answer. But I guess it's still possible that some older compilers don't support these functions. There's a suggested workaround, but we'd still need to know what compiler version to apply it to, and whether it works at all (it uses a different SIMD operation instead).

I can reproduce this with GCC 7.x, but not with GCC 8.x. It seems indeed that GCC 7.x is missing some intrinsics. I'd suggest applying the workaround from the SO post for versions of GCC <= 7.x. I'll check whether the suggested intrinsics are equivalent. This should be fairly easy to do.
Because I already have a setup that allows me to test this, I'll submit a PR soon-ish.

@nielsdos So I guess it means the entire PHP codebase should avoid the intrinsics which are not implemented in GCC 7.

@nielsdos So I guess it means the entire PHP codebase should avoid the intrinsics which are not implemented in GCC 7.

Avoid, or maybe polyfill like what I'm going to do here.
We could also create a common header for the polyfills if we encounter more of those cases.
I checked, and only mbstring uses _mm256_set_m128i.

Just checked the equivalence. The solution on SO is equivalent.

I tweaked the #if check such that the workaround only applies on GCC
versions older than 8.0.
I tested this with GCC 7.5, 8.4, 9.4, GCC 13.1.1, and Clang 10.0.

@SjonHortensius What distro + distro version do you use? And does your CPU support AVX2 ?

@nielsdos sorry I just realized this runs in a debian chroot with gcc 6.3. The cpu supports avx2. Should that work?

@SjonHortensius That should work. But I'm not seeing that instrinsic on line 5179: https://github.com/php/php-src/blob/master/ext/mbstring/mbstring.c#L5179
Are you sure you got the latest sources?
Also given that Debian dropped the gcc-6 package, I'd suggest to upgrade anyway
