Subject: Don't fast-isel an x87 comparison opcode, as fast-isel doesn't
X-Git-Url: http://plrg.eecs.uci.edu/git/?a=commitdiff_plain;h=be4d10d7fa6f81eda360b451b4baabe64534c74e;p=oota-llvm.git

Don't fast-isel an x87 comparison opcode, as fast-isel doesn't
support branching on x87 comparisons yet. This fixes PR7624.
