From 9a80c2e360df59546b36f76d559dbbbb1d0ec06d Mon Sep 17 00:00:00 2001 From: Bill Wendling Date: Mon, 15 Mar 2010 19:04:37 +0000 Subject: Place the LSDA into the TEXT section for x86 Darwin. If the global it's pointing to is local to the translation unit, we need to place fill the value of that symbol into the non-lazy pointer. This should conclude all Darwin changes for placing the LSDA into the TEXT section. There is some cleanup to do. I.e., there's no longer a special need for target-specific code here. But that can come later. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@98564 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/Target/X86/X86TargetObjectFile.cpp | 14 ++++++++++++++ 1 file changed, 14 insertions(+) (limited to 'lib/Target/X86/X86TargetObjectFile.cpp') diff --git a/lib/Target/X86/X86TargetObjectFile.cpp b/lib/Target/X86/X86TargetObjectFile.cpp index f49153b..755967b 100644 --- a/lib/Target/X86/X86TargetObjectFile.cpp +++ b/lib/Target/X86/X86TargetObjectFile.cpp @@ -12,12 +12,26 @@ #include "X86TargetMachine.h" #include "llvm/CodeGen/MachineModuleInfoImpls.h" #include "llvm/MC/MCContext.h" +#include "llvm/MC/MCSectionMachO.h" #include "llvm/Target/Mangler.h" #include "llvm/ADT/SmallString.h" #include "llvm/Support/Dwarf.h" using namespace llvm; using namespace dwarf; +void X86_MachoTargetObjectFile::Initialize(MCContext &Ctx, + const TargetMachine &TM) { + TargetLoweringObjectFileMachO::Initialize(Ctx, TM); + + // Exception Handling. + LSDASection = getMachOSection("__TEXT", "__gcc_except_tab", 0, + SectionKind::getReadOnlyWithRel()); +} + +unsigned X86_MachoTargetObjectFile::getTTypeEncoding() const { + return DW_EH_PE_indirect | DW_EH_PE_pcrel | DW_EH_PE_sdata4; +} + const MCExpr *X8664_MachoTargetObjectFile:: getExprForDwarfGlobalReference(const GlobalValue *GV, Mangler *Mang, MachineModuleInfo *MMI, unsigned Encoding, -- cgit v1.1
