Subject: Change logic in StackMaps::recordStackMapOpers to use the isInt<32>
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=60c2a98db4545717a546976db723400e3b1f9409;p=oota-llvm.git

Change logic in StackMaps::recordStackMapOpers to use the isInt<32>
predicate instead of bitwise operations.

This is not a functional change.
