Subject: this final call to canLosslesslyBitCastTo is dead, because ValueRequiresCast
X-Git-Url: http://plrg.eecs.uci.edu/git/?a=commitdiff_plain;h=80c6c3bbff5ad6af8e4f5903279fec7fb0c798f6;p=oota-llvm.git

this final call to canLosslesslyBitCastTo is dead, because ValueRequiresCast
is only called on integers.
