Subject: R600/SI: Remove apparently dead code in legalizeOperands
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=ea849e9adcbcba4b421e782d58a558397e2da611;p=oota-llvm.git

R600/SI: Remove apparently dead code in legalizeOperands

No tests hit this, and I don't see any way a GlobalAddress
node would survive beyond lowering on SI. It it would, the
move should probably be inserted by selection.
