From 5e693ed07b35f9ed123da9c977ba0f61d65a3a08 Mon Sep 17 00:00:00 2001 From: Chris Lattner Date: Tue, 28 Jul 2009 03:13:23 +0000 Subject: Rip all of the global variable lowering logic out of TargetAsmInfo. Since it is highly specific to the object file that will be generated in the end, this introduces a new TargetLoweringObjectFile interface that is implemented for each of ELF/MachO/COFF/Alpha/PIC16 and XCore. Though still is still a brutal and ugly refactoring, this is a major step towards goodness. This patch also: 1. fixes a bunch of dangling pointer problems in the PIC16 backend. 2. disables the TargetLowering copy ctor which PIC16 was accidentally using. 3. gets us closer to xcore having its own crazy target section flags and pic16 not having to shadow sections with its own objects. 4. fixes wierdness where ELF targets would set CStringSection but not CStringSection_. Factor the code better. 5. fixes some bugs in string lowering on ELF targets. llvm-svn: 77294 --- llvm/lib/Target/Sparc/SparcISelLowering.cpp | 25 ++++++++++++++++++++++++- 1 file changed, 24 insertions(+), 1 deletion(-) (limited to 'llvm/lib/Target/Sparc/SparcISelLowering.cpp') diff --git a/llvm/lib/Target/Sparc/SparcISelLowering.cpp b/llvm/lib/Target/Sparc/SparcISelLowering.cpp index fe7bf93ecc6..16d922985b2 100644 --- a/llvm/lib/Target/Sparc/SparcISelLowering.cpp +++ b/llvm/lib/Target/Sparc/SparcISelLowering.cpp @@ -21,6 +21,7 @@ #include "llvm/CodeGen/MachineInstrBuilder.h" #include "llvm/CodeGen/MachineRegisterInfo.h" #include "llvm/CodeGen/SelectionDAG.h" +#include "llvm/Target/TargetLoweringObjectFile.h" #include "llvm/ADT/VectorExtras.h" #include "llvm/Support/ErrorHandling.h" using namespace llvm; @@ -548,9 +549,31 @@ static SPCC::CondCodes FPCondCCodeToFCC(ISD::CondCode CC) { } } +class TargetLoweringObjectFileSparc : public TargetLoweringObjectFileELF { +public: + void getSectionFlagsAsString(SectionKind Kind, + SmallVectorImpl &Str) const { + if (Kind.isMergeableConst() || Kind.isMergeableCString()) + return TargetLoweringObjectFileELF::getSectionFlagsAsString(Kind, Str); + + // FIXME: Inefficient. + std::string Res; + if (!Kind.isMetadata()) + Res += ",#alloc"; + if (Kind.isText()) + Res += ",#execinstr"; + if (Kind.isWriteable()) + Res += ",#write"; + if (Kind.isThreadLocal()) + Res += ",#tls"; + + Str.append(Res.begin(), Res.end()); + } +}; + SparcTargetLowering::SparcTargetLowering(TargetMachine &TM) - : TargetLowering(TM) { + : TargetLowering(TM, new TargetLoweringObjectFileSparc()) { // Set up the register classes. addRegisterClass(MVT::i32, SP::IntRegsRegisterClass); -- cgit v1.2.3
