From bced5cd924e47818d67e33b3ae1550ab96fc239a Mon Sep 17 00:00:00 2001 From: Jakob Stoklund Olesen Date: Sat, 5 Jan 2013 04:38:12 +0000 Subject: Add MachineRegisterInfo::moveOperands(). This function works like memmove() for MachineOperands, except it also updates any use-def chains containing the moved operands. The use-def chains are updated without affecting the order of operands in the list. That isn't possible when using the removeRegOperandFromUseList() and addRegOperandToUseList() functions. Callers to follow soon. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@171597 91177308-0d34-0410-b5e6-96231b3b80d8 --- include/llvm/CodeGen/MachineRegisterInfo.h | 3 +++ 1 file changed, 3 insertions(+) (limited to 'include/llvm/CodeGen/MachineRegisterInfo.h') diff --git a/include/llvm/CodeGen/MachineRegisterInfo.h b/include/llvm/CodeGen/MachineRegisterInfo.h index 0cf584f..36427e9 100644 --- a/include/llvm/CodeGen/MachineRegisterInfo.h +++ b/include/llvm/CodeGen/MachineRegisterInfo.h @@ -156,6 +156,9 @@ public: // Strictly for use by MachineInstr.cpp. void removeRegOperandFromUseList(MachineOperand *MO); + // Strictly for use by MachineInstr.cpp. + void moveOperands(MachineOperand *Dst, MachineOperand *Src, unsigned NumOps); + /// reg_begin/reg_end - Provide iteration support to walk over all definitions /// and uses of a register within the MachineFunction that corresponds to this /// MachineRegisterInfo object. -- cgit v1.1
