Unsupported SHA-NI #9

Closed mrx23dot closed 1 year ago

mrx23dot commented 2 years ago

I have a kinda new CPU i7 10510U cpuZ says: Instructions sets: MMX, SSE, SSE2, SSE3, SSSE3, SSE4.1, SSE4.2, EM64T, VT-x, AES, AVX, AVX2, FMA3

but gcc -msse4 -msha cpuid.c says "This CPU does not support SHA-NI"

Also intel pdf only mentions sha1 and sha256 extension, not 512.

AFAIK, SHA256 native instruction is Rocket lake (gen 11) and up (https://en.wikipedia.org/wiki/Intel_SHA_extensions) so you're out of luck, since you have gen 10
