Subject: Add more pattern matchers for compares, instructions, and BinaryOperators. NFC.
X-Git-Url: http://plrg.eecs.uci.edu/git/?a=commitdiff_plain;h=c4dedab6a67766053553b1c8d095c633b4e57e4c;p=oota-llvm.git

Add more pattern matchers for compares, instructions, and BinaryOperators. NFC.

Add a few more matchers to make the code in the next commit more compact.
