From 25c1653700d94cd5cbb0bce47ee6687f6379750b Mon Sep 17 00:00:00 2001 From: Dan Gohman Date: Sat, 1 May 2010 00:01:06 +0000 Subject: Get rid of the EdgeMapping map. Instead, just check for BasicBlock changes before doing phi lowering for switches. llvm-svn: 102809 --- llvm/lib/Target/SystemZ/SystemZISelLowering.cpp | 7 +------ 1 file changed, 1 insertion(+), 6 deletions(-) (limited to 'llvm/lib/Target/SystemZ/SystemZISelLowering.cpp') diff --git a/llvm/lib/Target/SystemZ/SystemZISelLowering.cpp b/llvm/lib/Target/SystemZ/SystemZISelLowering.cpp index ac6536c701d..e98f18b9a31 100644 --- a/llvm/lib/Target/SystemZ/SystemZISelLowering.cpp +++ b/llvm/lib/Target/SystemZ/SystemZISelLowering.cpp @@ -799,8 +799,7 @@ const char *SystemZTargetLowering::getTargetNodeName(unsigned Opcode) const { MachineBasicBlock* SystemZTargetLowering::EmitInstrWithCustomInserter(MachineInstr *MI, - MachineBasicBlock *BB, - DenseMap *EM) const { + MachineBasicBlock *BB) const { const SystemZInstrInfo &TII = *TM.getInstrInfo(); DebugLoc dl = MI->getDebugLoc(); assert((MI->getOpcode() == SystemZ::Select32 || @@ -831,10 +830,6 @@ SystemZTargetLowering::EmitInstrWithCustomInserter(MachineInstr *MI, BuildMI(BB, dl, TII.getBrCond(CC)).addMBB(copy1MBB); F->insert(I, copy0MBB); F->insert(I, copy1MBB); - // Inform sdisel of the edge changes. - for (MachineBasicBlock::succ_iterator SI = BB->succ_begin(), - SE = BB->succ_end(); SI != SE; ++SI) - EM->insert(std::make_pair(*SI, copy1MBB)); // Update machine-CFG edges by transferring all successors of the current // block to the new block which will contain the Phi node for the select. copy1MBB->transferSuccessors(BB); -- cgit v1.2.3
