https://git.php.net/?p=php-src.git;a=commitdiff;h=edccf32f7f36a8bc759b9482737e0c3efcb3a005

breaks build on sandybridge (export 'CFLAGS=-m64 -O3 -mfpmath=sse -msse2avx -mavx -march=sandybridge -mtune=sandybridge..')

--------------------

the last working 7.4 commit:

Fix bug #77930: Remove mmap limit 	commit | commitdiff | tree | snapshot (zip tar.gz)

--------------------

smells like the binary contains AVX2 code which is called at runtime

Before reverting this, I'd like to understand why it causes a problem, because I really don't see it based on code inspection alone...

Could you please provide your configure output, or at least what the result for these four queries are?

checking for __builtin_cpu_init... yes
checking for __builtin_cpu_supports... yes
...
checking for __attribute__((ifunc))... yes
checking for __attribute__((target))... yes

the change itself is completly justified, it don't change limit runtime instructions at configure time but as it looks now without doing so the runtime checks are acting wrong while before AVX2 likely was filtered out completly

Looks like you have both ifunc resolvers and cpu builtins, so that's pretty standard.

The machine code at the segfault location also doesn't look like it's using AVX2, so possibly the crash is in the detection code itself.

Would it be possible to run PHP under gdb (or by loading the coredump in gdb) and get the "backtrace" and "disassemble" results?
