From 6a66e585b8242b9764ec3343309697d24bb1e312 Mon Sep 17 00:00:00 2001 From: Chris Lattner Date: Tue, 18 Aug 2009 06:13:03 +0000 Subject: [PATCH] add a horrible hack to the dwarf printer. It looks like mingw is not specifying an EHFrame section, so we just emit ehframe data into a random section. This is clearly bad. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79323 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/CodeGen/AsmPrinter/DwarfException.cpp | 12 +++++++++--- 1 file changed, 9 insertions(+), 3 deletions(-) diff --git a/lib/CodeGen/AsmPrinter/DwarfException.cpp b/lib/CodeGen/AsmPrinter/DwarfException.cpp index 1d773ee53e7..7ab0bb0975a 100644 --- a/lib/CodeGen/AsmPrinter/DwarfException.cpp +++ b/lib/CodeGen/AsmPrinter/DwarfException.cpp @@ -56,7 +56,10 @@ void DwarfException::EmitCommonEHFrame(const Function *Personality, TD->getPointerSize() : -TD->getPointerSize(); // Begin eh frame section. - Asm->SwitchToSection(Asm->getObjFileLowering().getEHFrameSection()); + // FIXME: THIS IS A HORRIBLE HACK.
