From be9fe49b179a89a659fe786d64b176d2b360bb4a Mon Sep 17 00:00:00 2001 From: Lang Hames Date: Mon, 2 Apr 2012 19:58:43 +0000 Subject: During two-address lowering, rescheduling an instruction does not untie operands. Make TryInstructionTransform return false to reflect this. Fixes PR11861. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@153892 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/CodeGen/TwoAddressInstructionPass.cpp | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'lib/CodeGen/TwoAddressInstructionPass.cpp') diff --git a/lib/CodeGen/TwoAddressInstructionPass.cpp b/lib/CodeGen/TwoAddressInstructionPass.cpp index 24b8bc2048..789617ba7f 100644 --- a/lib/CodeGen/TwoAddressInstructionPass.cpp +++ b/lib/CodeGen/TwoAddressInstructionPass.cpp @@ -1248,7 +1248,7 @@ TryInstructionTransform(MachineBasicBlock::iterator &mi, // re-schedule this MI below it. if (RescheduleMIBelowKill(mbbi, mi, nmi, regB)) { ++NumReSchedDowns; - return true; + return false; } if (TargetRegisterInfo::isVirtualRegister(regA)) @@ -1270,7 +1270,7 @@ TryInstructionTransform(MachineBasicBlock::iterator &mi, // re-schedule it before this MI if it's legal. if (RescheduleKillAboveMI(mbbi, mi, nmi, regB)) { ++NumReSchedUps; - return true; + return false; } // If this is an instruction with a load folded into it, try unfolding -- cgit v1.2.3-70-g09d2
