Subject: [X86] Add CMOV feature to 'i686' processor, making it a proper alias of pentiumpro... 
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=3f1a9263fc00af32309f04b4afdfb1a91219bcdf;p=llvm

[X86] Add CMOV feature to 'i686' processor, making it a proper alias of pentiumpro which I believe it should be.

This is consistent with current gcc behavior.
