From 62990bafa327cf8d95be19363f636ca60b505a91 Mon Sep 17 00:00:00 2001 From: Anton Korobeynikov Date: Thu, 21 Aug 2008 17:33:01 +0000 Subject: Allow inline asm nodes with empty bodies inside JIT. This unbreaks explicit reg vars inside JIT, which are implemented in such hacky way :) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@55128 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/Target/X86/X86CodeEmitter.cpp | 8 ++++++-- 1 file changed, 6 insertions(+), 2 deletions(-) (limited to 'lib/Target/X86/X86CodeEmitter.cpp') diff --git a/lib/Target/X86/X86CodeEmitter.cpp b/lib/Target/X86/X86CodeEmitter.cpp index ec93eb413d..c3a1ed921a 100644 --- a/lib/Target/X86/X86CodeEmitter.cpp +++ b/lib/Target/X86/X86CodeEmitter.cpp @@ -486,9 +486,13 @@ void Emitter::emitInstruction(const MachineInstr &MI, default: assert(0 && "psuedo instructions should be removed before code emission"); break; - case TargetInstrInfo::INLINEASM: - assert(0 && "JIT does not support inline asm!\n"); + case TargetInstrInfo::INLINEASM: { + const char* Value = MI.getOperand(0).getSymbolName(); + /* We allow inline assembler nodes with empty bodies - they can + implicitly define registers, which is ok for JIT. */ + assert((Value[0] == 0) && "JIT does not support inline asm!\n"); break; + } case TargetInstrInfo::DBG_LABEL: case TargetInstrInfo::EH_LABEL: MCE.emitLabel(MI.getOperand(0).getImm()); -- cgit v1.2.3
