Subject: If the tied registers are already the same, there is no need to change
X-Git-Url: http://plrg.eecs.uci.edu/git/?a=commitdiff_plain;h=d4034b2825a2a030893593327d67ca12b4e8a249;p=oota-llvm.git

If the tied registers are already the same, there is no need to change
them.  Move the code to make that change inside the conditional.
