Subject: Grab the TargetRegisterInfo off of the subtarget from the
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=c586355b060d2ac915d5c06e656671f486976a59;p=oota-llvm.git

Grab the TargetRegisterInfo off of the subtarget from the
MachineFunction rather than a lookup on the TargetMachine
to avoid unnecessary lookups.
