Thread: pgsql: Include _mm512_zextsi128_si512() in AVX-512 configure probes.
Include _mm512_zextsi128_si512() in AVX-512 configure probes. Commit 43da39430 added a dependency on this intrinsic to our AVX-512 CRC code. It turns out this intrinsic was added to gcc later than the other ones we were using, so that there are platforms where the new code fails to compile. Since only relatively old (pre-gcc-10) compilers are affected, it doesn't seem worth trying to make the AVX-512 CRC code actually work on these platforms. Just add the new intrinsic to the configure probe, so that we'll conclude the code can't be built.
