From b56606274d43c7a3e01b18a08d1115fbf2889996 Mon Sep 17 00:00:00 2001 From: Chad Rosier Date: Sat, 16 Feb 2013 01:25:28 +0000 Subject: [ms-inline asm] Do not omit the frame pointer if we have ms-inline assembly. If the frame pointer is omitted, and any stack changes occur in the inline assembly, e.g.: "pusha", then any C local variable or C argument references will be incorrect. I pass no judgement on anyone who would do such a thing. ;) rdar://13218191 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@175334 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/Target/X86/X86FrameLowering.cpp | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'lib/Target/X86') diff --git a/lib/Target/X86/X86FrameLowering.cpp b/lib/Target/X86/X86FrameLowering.cpp index 84b1c10..950fd39 100644 --- a/lib/Target/X86/X86FrameLowering.cpp +++ b/lib/Target/X86/X86FrameLowering.cpp @@ -50,7 +50,7 @@ bool X86FrameLowering::hasFP(const MachineFunction &MF) const { return (MF.getTarget().Options.DisableFramePointerElim(MF) || RegInfo->needsStackRealignment(MF) || MFI->hasVarSizedObjects() || - MFI->isFrameAddressTaken() || + MFI->isFrameAddressTaken() || MF.hasMSInlineAsm() || MF.getInfo()->getForceFramePointer() || MMI.callsUnwindInit() || MMI.callsEHReturn()); } -- cgit v1.1
