Subject: Return the base register of a register list for the "getReg()" method. This is
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=8155e5b753aca42973cf317727f3805faddcaf90;p=oota-llvm.git

Return the base register of a register list for the "getReg()" method. This is
to satisfy the ClassifyOperand method of the Asm matcher without having to add a
RegList type to every back-end.
