Subject: Use FrameSetup on frame instructions for the Mips port.
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=7c3419168394ed14b3114bfaa9bc0eaf7fd5e5fb;p=oota-llvm.git

Use FrameSetup on frame instructions for the Mips port.

I can't seem to get a testcase to show a difference here, but it's
part of the unconditional-br.ll line table weirdness.
