From 66bfdb8354ccb24ded9ecee0ac80aa7c103c2fa4 Mon Sep 17 00:00:00 2001 From: Kai Nacke Date: Sat, 6 Jul 2013 17:15:36 +0000 Subject: Fix wrong code offset for unwind code SET_FPREG. The code offset for unwind code SET_FPREG is wrong because it is set to constant 0. The fix is to do the same as for the other unwind codes: emit a label and later the absolute difference between the label and the begin of the prologue. Also enables the failing test case MC/COFF/seh.s Reviewed by Charles Davis and Nico Rieck. llvm-svn: 185758 --- llvm/lib/MC/MCStreamer.cpp | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) (limited to 'llvm/lib/MC/MCStreamer.cpp') diff --git a/llvm/lib/MC/MCStreamer.cpp b/llvm/lib/MC/MCStreamer.cpp index 6542f42a03b..fb43a4adbda 100644 --- a/llvm/lib/MC/MCStreamer.cpp +++ b/llvm/lib/MC/MCStreamer.cpp @@ -470,7 +470,9 @@ void MCStreamer::EmitWin64EHSetFrame(unsigned Register, unsigned Offset) { report_fatal_error("Frame register and offset already specified!"); if (Offset & 0x0F) report_fatal_error("Misaligned frame pointer offset!"); - MCWin64EHInstruction Inst(Win64EH::UOP_SetFPReg, 0, Register, Offset); + MCSymbol *Label = getContext().CreateTempSymbol(); + MCWin64EHInstruction Inst(Win64EH::UOP_SetFPReg, Label, Register, Offset); + EmitLabel(Label); CurFrame->LastFrameInst = CurFrame->Instructions.size(); CurFrame->Instructions.push_back(Inst); } -- cgit v1.2.3
