Lu <hjl.to...@gmail.com> Date: Tue Sep 27 16:19:11 2022 -0700 i386: Mark XMM4-XMM6 as clobbered by encodekey128/encodekey256 encodekey128 and encodekey256 operations clear XMM4-XMM6. But it is documented that XMM4-XMM6 are reserved for future usages and software should not rely upon them being zeroed. Change encodekey128 and encodekey256 to clobber XMM4-XMM6. gcc/ PR target/107061 * config/i386/predicates.md (encodekey128_operation): Check XMM4-XMM6 as clobbered. (encodekey256_operation): Likewise. * config/i386/sse.md (encodekey128u32): Clobber XMM4-XMM6.
