Subject: [PATCH] x86: fix SSE4a dependencies of ".arch .nosse*"
Date: Wed, 12 Feb 2020 17:08:00 -0000 [thread overview]
Message-ID: <3bc597bb-10f9-80f9-8e00-f28aeb2eea77@suse.com> (raw)
Since ".arch sse4a" enables SSE3 and earlier, disabling SSE3 should also
disable SSE4a. And as per its name, ".arch .nosse4" should also do so.

* config/tc-i386.c (cpu_noarch): Use CPU_ANY_SSE4_FLAGS in
"nosse4" entry.
opcodes/
2020-02-XX Jan Beulich <jbeulich@suse.com>
* i386-gen.c (cpu_flag_init): Move CpuSSE4a from
CPU_ANY_SSE_FLAGS entry to CPU_ANY_SSE3_FLAGS one. Add
CPU_ANY_SSE4_FLAGS entry.
* i386-init.h: Re-generate.
