2011-04-11Just because a GlobalVariable's initializer is [N x { i32, void ()* }] doesn'tNick Lewycky1-1/+5
mean that it has to be ConstantArray of ConstantStruct. We might have ConstantAggregateZero, at either level, so don't crash on that. Also, semi-deprecate the sentinal value. The linker isn't aware of sentinals so we end up with the two lists appended, each with their "sentinals" on them. Different parts of LLVM treated sentinals differently, so make them all just ignore the single entry and continue on with the rest of the list. llvm-svn: 129307

2009-10-05strength reduce a ton of type equality tests to check the typeid (ThroughChris Lattner1-7/+6
the new predicates I added) instead of going through a context and doing a pointer comparison. Besides being cheaper, this allows a smart compiler to turn the if sequence into a switch. llvm-svn: 83297

2009-08-13Remove hack used to strip unwanted chars from section nameBruno Cardoso Lopes1-98/+64
Use MCSectionELF methods as much as possible, removing some ELFWriter methods which are now unused llvm-svn: 78940
2009-08-13Change MCSectionELF to represent a section semantically instead ofBruno Cardoso Lopes1-16/+20
syntactically as a string, very similiar to what Chris did with MachO. The parsing support and validation is not introduced yet. llvm-svn: 78890

2009-08-08sink the 'name' and 'isdirective' state out of MCSection into its derived ↵Chris Lattner1-8/+12
classes. This totally optimizes PIC16 sections by not having an 'isdirective' bit anymore!! ;-) llvm-svn: 78517
2009-08-08ELF improvements:Bruno Cardoso Lopes1-53/+87
Handle large integers, x86_fp80, ConstantAggregateZero, and two more ConstantExpr: GetElementPtr and IntToPtr Set SHF_MERGE bit for mergeable strings Avoid zero initialized strings to be classified as a bss symbol Don't allow common symbols to be classified as STB_WEAK Add a constant to be used as a global value offset in data relocations llvm-svn: 78476
2009-08-05- Remove custom handling of jumptables by the elf writter (this wasBruno Cardoso Lopes1-77/+157
a dirty hack and isn't need anymore since the last x86 code emitter patch) - Add a target-dependent modifier to addend calculation - Use R_X86_64_32S relocation for X86::reloc_absolute_word_sext - Use getELFSectionFlags whenever possible - fix getTextSection to use TLOF and emit the right text section - Handle global emission for static ctors, dtors and Type::PointerTyID - Some minor fixes llvm-svn: 78176
2009-08-02remove the dead ELFTargetAsmInfo.h/cpp file. TargetAsmInfoChris Lattner1-1/+1
defaults to being ELF. llvm-svn: 77866
2009-08-01(re)introduce new simpler apis for creation sectionkinds.Chris Lattner1-8/+7
llvm-svn: 77834
2009-08-01Remove "JumpTableDataSection" from TAI, instead, have AsmPrinterChris Lattner1-2/+8
compute it based on what it knows. As part of this, rename getSectionForMergeableConstant to getSectionForConstant because it works for non-mergable constants also. The only functionality change from this is that Xcore will start dropping its jump tables into readonly section instead of data section in -static mode. This should be fine as the linker resolves the relocations. If this is a problem, let me know and we'll come up with another solution. llvm-svn: 77833
2009-08-01Change SectionKind to be a property that is true of a *section*, itChris Lattner1-6/+6
should have no state that is specific to particular globals in the section. In this case, it means the removal of the "isWeak" and "ExplicitSection" bits. MCSection uses the new form of SectionKind. To handle isWeak, I introduced a new SectionInfo class, which is SectionKind + isWeak, and it is used by the part of the code generator that does classification of a specific global. The ExplicitSection disappears. It is moved onto MCSection as a new "IsDirective" bit. Since the Name of a section is either a section or directive, it makes sense to keep this bit in MCSection. Ultimately the creator of MCSection should canonicalize (e.g.) .text to whatever the actual section is. llvm-svn: 77803
2009-07-31switch off of 'Section' onto MCSection. We're not properly usingChris Lattner1-2/+3
MCSection subclasses yet, but this is a step in the right direction. llvm-svn: 77708
2009-07-31refactor section construction in TLOF to be through an explicitChris Lattner1-0/+8
initialize method, which can be called when an MCContext is available. llvm-svn: 77687

No functionality change. llvm-svn: 77432

llvm-svn: 77354
2009-07-28Rip all of the global variable lowering logic out of TargetAsmInfo. SinceChris Lattner1-2/+10
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
