From fb19f9402b4fe837663c793c42d85ae3c0dbb8ba 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. llvm-svn: 52943 --- llvm/lib/Target/X86/X86CodeEmitter.cpp | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) (limited to 'llvm/lib/Target/X86/X86CodeEmitter.cpp') diff --git a/llvm/lib/Target/X86/X86CodeEmitter.cpp b/llvm/lib/Target/X86/X86CodeEmitter.cpp index 82604a8b59f..1b2d5ffc3e6 100644 --- a/llvm/lib/Target/X86/X86CodeEmitter.cpp +++ b/llvm/lib/Target/X86/X86CodeEmitter.cpp @@ -490,7 +490,8 @@ void Emitter::emitInstruction(const MachineInstr &MI, case TargetInstrInfo::INLINEASM: assert(0 && "JIT does not support inline asm!\n"); break; - case TargetInstrInfo::LABEL: + case TargetInstrInfo::DBG_LABEL: + case TargetInstrInfo::EH_LABEL: MCE.emitLabel(MI.getOperand(0).getImm()); break; case TargetInstrInfo::IMPLICIT_DEF: -- cgit v1.2.3
