Bug ID: 115618
Summary: GCC 13.3 should defined __ARM_FEATURE_CRYPTO with
+aes+sha2
Product: gcc
Version: 13.3.1
Status: UNCONFIRMED
Keywords: rejects-valid
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: ktkachov at gcc dot gnu.org
CC: tnfchris at gcc dot gnu.org
Target Milestone: ---
Target: aarch64
I think this has been fixed in GCC 14 onwards but we're seeing
__ARM_FEATURE_CRYPTO missing from some -mcpu=native cases that should be
including it (the prerequisite "aes pmull sha1 sha2" info exists in cpuinfo)
with GCC 13-based compilers.
I think this can be reproduced with:
#ifndef __ARM_FEATURE_CRYPTO
#error "__ARM_FEATURE_CRYPTO should be defined!"
#endif
void
foo (void)
{
}
compiled with GCC 13.3 with -march=armv9-a+aes+sha2 gives an error but it works
with GCC 14.1. I remember there was much rework in this area, could something
be backported to the branch?
