From 4406604047423576e36657c7ede266ca42e79642 Mon Sep 17 00:00:00 2001 From: Dan Gohman Date: Tue, 1 Jul 2008 00:05:16 +0000 Subject: Split ISD::LABEL into ISD::DBG_LABEL and ISD::EH_LABEL, eliminating the need for a flavor operand, and add a new SDNode subclass, LabelSDNode, for use with them to eliminate the need for a label id operand. Change instruction selection to let these label nodes through unmodified instead of creating copies of them. Teach the MachineInstr emitter how to emit a MachineInstr directly from an ISD label node. This avoids the need for allocating SDNodes for the label id and flavor value, as well as SDNodes for each of the post-isel label, label id, and label flavor. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@52943 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/Target/PowerPC/PPCInstrInfo.cpp | 5 +++-- 1 file changed, 3 insertions(+), 2 deletions(-) (limited to 'lib/Target/PowerPC/PPCInstrInfo.cpp') diff --git a/lib/Target/PowerPC/PPCInstrInfo.cpp b/lib/Target/PowerPC/PPCInstrInfo.cpp index d7adea3c77..378fa4bf4d 100644 --- a/lib/Target/PowerPC/PPCInstrInfo.cpp +++ b/lib/Target/PowerPC/PPCInstrInfo.cpp @@ -754,9 +754,10 @@ unsigned PPCInstrInfo::GetInstSizeInBytes(const MachineInstr *MI) const { const char *AsmStr = MI->getOperand(0).getSymbolName(); return MF->getTarget().getTargetAsmInfo()->getInlineAsmLength(AsmStr); } - case PPC::LABEL: { + case PPC::DBG_LABEL: + case PPC::EH_LABEL: + case PPC::GC_LABEL: return 0; - } default: return 4; // PowerPC instructions are all 4 bytes } -- cgit v1.2.3-70-g09d2
