Subject: Expose hasLiveCondCodeDef as a member function of the X86InstrInfo class. NFC
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=ab3081c118fe3143628624a46db0f5d7dd874476;p=oota-llvm.git

Expose hasLiveCondCodeDef as a member function of the X86InstrInfo class. NFC

This takes the existing static function hasLiveCondCodeDef and makes it a member function of the X86InstrInfo class. This is a useful utility function that an upcoming change would like to use. NFC.
