Subject: MachineOperand::setIsDebug should ensure the register is /not/ a definition
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=b7770e0b851295141f2b5ec8383380253a75c5f8;p=oota-llvm.git

MachineOperand::setIsDebug should ensure the register is /not/ a definition

This currently unused function appeared to be asserting in the wrong
direction - DebugValues are never definitions of registers, only uses.
Curiously we don't perform any of these checks for the more common (&
actually used) case of MachineOperand::CreateReg (or other Create
functions).
