From 3d7780580131bf5a736412bcc3b11610721bd3e2 Mon Sep 17 00:00:00 2001 From: Chris Lattner Date: Sun, 2 Aug 2009 01:34:32 +0000 Subject: move getDwarfExceptionSection from TAI to TLOF and rename it to getLSDASection() to be more specific. This makes it pretty obvious that the ELF LSDA section is being specified wrong in PIC mode. We're probably getting a lot of startup-time relocations to a readonly page, which is expensive and bad. Someone who cares about ELF C++ should investigate this. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77847 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/CodeGen/AsmPrinter/DwarfException.cpp | 9 ++++----- 1 file changed, 4 insertions(+), 5 deletions(-) (limited to 'lib/CodeGen/AsmPrinter/DwarfException.cpp') diff --git a/lib/CodeGen/AsmPrinter/DwarfException.cpp b/lib/CodeGen/AsmPrinter/DwarfException.cpp index 8eb97af..b051f71 100644 --- a/lib/CodeGen/AsmPrinter/DwarfException.cpp +++ b/lib/CodeGen/AsmPrinter/DwarfException.cpp @@ -20,10 +20,11 @@ #include "llvm/Support/Timer.h" #include "llvm/Support/raw_ostream.h" #include "llvm/Target/TargetAsmInfo.h" -#include "llvm/Target/TargetRegisterInfo.h" #include "llvm/Target/TargetData.h" #include "llvm/Target/TargetFrameInfo.h" +#include "llvm/Target/TargetLoweringObjectFile.h" #include "llvm/Target/TargetOptions.h" +#include "llvm/Target/TargetRegisterInfo.h" #include "llvm/ADT/StringExtras.h" using namespace llvm; @@ -539,10 +540,8 @@ void DwarfException::EmitExceptionTable() { unsigned SizeAlign = (4 - TotalSize) & 3; // Begin the exception table. - //MCSection *LSDASection = TAI->getLSDASection(); - //Asm->SwitchToSection(LSDASection); - - Asm->SwitchToDataSection(TAI->getDwarfExceptionSection()); + const MCSection *LSDASection = Asm->getObjFileLowering().getLSDASection(); + Asm->SwitchToSection(LSDASection); Asm->EmitAlignment(2, 0, 0, false); O << "GCC_except_table" << SubprogramCount << ":\n"; -- cgit v1.1
