Subject: x86: fix SSE4a dependencies of ".arch .nosse*"
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=7deea9aad8;p=deliverable%2Fbinutils-gdb.git

x86: fix SSE4a dependencies of ".arch .nosse*"

Since ".arch .sse4a" enables SSE3 and earlier, disabling SSE3 should
also disable SSE4a. And as per its name, ".arch .nosse4" should also do
so.
