I'm trying to determine if GCC has a __builtin_cpu_supports for SHA-1 and SHA-256 on x86 processors. The man page is at https://gcc.gnu.org/onlinedocs/gcc/x86-Built-in-Functions.html, but I don't see them listed. But I am also not sure the docs are up to date. However, SHA is supported in multifunctions. Does GCC __builtin_cpu_supports handle x86 SHA-1 and SHA-256? Thanks in advance.
