Subject: Revert "Debug Info: Bail out of AddMachineRegPiece() if MachineReg is not a"
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=4e5d08aad045b41e4f57914de22db9d4575f0a8b;p=oota-llvm.git

Revert "Debug Info: Bail out of AddMachineRegPiece() if MachineReg is not a"

This reverts commit r225852, it was a bad idea.

MachineReg should always be a physical register. If it isn't this DebugLoc
shouldn't have been created in the first place.
