From d062bf740651c35ed3ee80b66b02d8363fd14a3a Mon Sep 17 00:00:00 2001 From: Evan Cheng Date: Wed, 23 Sep 2009 06:28:31 +0000 Subject: Fix PR5024. LiveVariables physical register defs should *commit* only after all of the defs are processed. Also fix a implicit_def propagation bug: a implicit_def of a physical register should be applied to uses of the sub-registers. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@82616 91177308-0d34-0410-b5e6-96231b3b80d8 --- include/llvm/CodeGen/LiveVariables.h | 6 +++++- 1 file changed, 5 insertions(+), 1 deletion(-) (limited to 'include') diff --git a/include/llvm/CodeGen/LiveVariables.h b/include/llvm/CodeGen/LiveVariables.h index 52d5595..45c72f5 100644 --- a/include/llvm/CodeGen/LiveVariables.h +++ b/include/llvm/CodeGen/LiveVariables.h @@ -149,7 +149,11 @@ private: // Intermediate data structures bool HandlePhysRegKill(unsigned Reg, MachineInstr *MI); void HandlePhysRegUse(unsigned Reg, MachineInstr *MI); - void HandlePhysRegDef(unsigned Reg, MachineInstr *MI); + void HandlePhysRegDef(unsigned Reg, MachineInstr *MI, + SmallVector &Defs, + SmallVector &SuperDefs); + void UpdatePhysRegDefs(MachineInstr *MI, SmallVector &Defs); + void UpdateSuperRegDefs(MachineInstr *MI, SmallVector &Defs); /// FindLastPartialDef - Return the last partial def of the specified register. /// Also returns the sub-registers that're defined by the instruction. -- cgit v1.1
