From 940f83e772ca2007d62faffc83094bd7e8da6401 Mon Sep 17 00:00:00 2001 From: Owen Anderson Date: Tue, 26 Aug 2008 18:03:31 +0000 Subject: Make TargetInstrInfo::copyRegToReg return a bool indicating whether the copy requested was inserted or not. This allows bitcast in fast isel to properly handle the case where an appropriate reg-to-reg copy is not available. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@55375 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/Target/CellSPU/SPUInstrInfo.cpp | 8 +++++--- 1 file changed, 5 insertions(+), 3 deletions(-) (limited to 'lib/Target/CellSPU/SPUInstrInfo.cpp') diff --git a/lib/Target/CellSPU/SPUInstrInfo.cpp b/lib/Target/CellSPU/SPUInstrInfo.cpp index 3998b984b2..02490e95c8 100644 --- a/lib/Target/CellSPU/SPUInstrInfo.cpp +++ b/lib/Target/CellSPU/SPUInstrInfo.cpp @@ -180,7 +180,7 @@ SPUInstrInfo::isStoreToStackSlot(MachineInstr *MI, int &FrameIndex) const { return 0; } -void SPUInstrInfo::copyRegToReg(MachineBasicBlock &MBB, +bool SPUInstrInfo::copyRegToReg(MachineBasicBlock &MBB, MachineBasicBlock::iterator MI, unsigned DestReg, unsigned SrcReg, const TargetRegisterClass *DestRC, @@ -218,9 +218,11 @@ void SPUInstrInfo::copyRegToReg(MachineBasicBlock &MBB, BuildMI(MBB, MI, get(SPU::ORv4i32), DestReg).addReg(SrcReg) .addReg(SrcReg); } else { - cerr << "Attempt to copy unknown/unsupported register class!\n"; - abort(); + // Attempt to copy unknown/unsupported register class! + return false; } + + return true; } void -- cgit v1.2.3-70-g09d2
