Juergen Ributzka 9c01dd36f8 [CodeGenPrepare] Split branch conditions into multiple conditional branches. ... This optimization transforms code like: bb1: %0 = icmp ne i32 %a, 0 %1 = icmp ne i32 %b, 0 %or.cond = or i1 %0, %1 br i1 %or.cond, label %TrueBB, label %FalseBB into a multiple branch instructions like: bb1: %0 = icmp ne i32 %a, 0 br i1 %0, label %TrueBB, label %bb2 bb2: %1 = icmp ne i32 %b, 0 br i1 %1, label %TrueBB, label %FalseBB This optimization is already performed by SelectionDAG, but not by FastISel. FastISel cannot perform this optimization, because it cannot generate new MachineBasicBlocks. Performing this optimization at CodeGenPrepare time makes it available to both - SelectionDAG and FastISel - and the implementation in SelectiuonDAG could be removed. There are currenty a few differences in codegen for X86 and PPC, so this commmit only enables it for FastISel.
