Subject: Avoid calling removeVirtualRegisterKilled which iterates over the operands
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=86f7cd786eecc74e0480c0f8ab6a4234bb72bfbb;p=oota-llvm.git

Avoid calling removeVirtualRegisterKilled which iterates over the operands
to find the kill, since we already have the operand.
