From 1015ba7018c87f48cc7bb45a564eb4a27241e76a Mon Sep 17 00:00:00 2001 From: Evan Cheng Date: Fri, 21 May 2010 20:53:24 +0000 Subject: - Change MachineInstr::findRegisterDefOperandIdx so it can also look for defs that are aliases of the specified register. - Rename modifiesRegister to definesRegister since it's looking a def of the specific register or one of its super-registers. It's not looking for def of a sub-register or alias that could change the specified register. - Added modifiesRegister to look for defs of aliases. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@104377 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/CodeGen/TwoAddressInstructionPass.cpp | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'lib/CodeGen/TwoAddressInstructionPass.cpp') diff --git a/lib/CodeGen/TwoAddressInstructionPass.cpp b/lib/CodeGen/TwoAddressInstructionPass.cpp index 21e5a5a9f2..3d10dc13d2 100644 --- a/lib/CodeGen/TwoAddressInstructionPass.cpp +++ b/lib/CodeGen/TwoAddressInstructionPass.cpp @@ -780,7 +780,7 @@ canUpdateDeletedKills(SmallVector &Kills, if (!LastKill) return false; - bool isModRef = LastKill->modifiesRegister(Kill); + bool isModRef = LastKill->definesRegister(Kill); NewKills.push_back(std::make_pair(std::make_pair(Kill, isModRef), LastKill)); } -- cgit v1.2.3-70-g09d2
