Bug ID: 98460
Summary: _builtin_cpu_supports("sha") missing
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: felix-gcc at fefe dot de
Target Milestone: ---
gcc offers a useful builtin around the cpuid instruction on x86 and x86_64,
which can be used to check for specific instruction set extensions, e.g.
if (_builtin_cpu_supports("avx2"))
I need to check for the SHA-NI extension, which does not appear to be
supported.
However, checking for AES-NI is supported with the string "aes".
