2010-11-19Added support for the Mach-O .symbol_resolver directive. rdar://8673046Kevin Enderby
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119816 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-19Change some methods in MCDwarf.cpp to be able to handle an arbitraryRafael Espindola
MCStreamer instead of just MCObjectStreamer. Address changes cannot be as efficient as we have to use DW_LNE_set_addres, but at least most of the logic is shared. This will be used so that, with CodeGen still using EmitDwarfLocDirective, llvm-gcc is able to produce debug_line sections without needing an assembler that supports .loc. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119777 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-16Add .loc methods to the streamer.Rafael Espindola
Next: Add support for the !HasDotLocAndDotFile case to the MCAsmStreamer and then switch codegen to use it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119384 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-15Change MCExpr::EvaluateAsRelocatableImpl of variables to return the originalRafael Espindola
variable if recursing fails to simplify it. Factor AliasedSymbol to be a method of MCSymbol. Update MCAssembler::EvaluateFixup to match the change in EvaluateAsRelocatableImpl. Remove the WeakRefExpr hack, as the object writer now sees the weakref with no extra effort needed. Nothing else is using MCTargetExpr, but keep it for now. Now that the ELF writer sees relocations with aliases, handle .weak foo2 foo2: .weak bar2 .set bar2,foo2 .quad bar2 the same way gas does and produce a relocation with bar2. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119152 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-14Fix another case of a .comm directive without a corresponding .typeRafael Espindola
directive. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119073 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-14Fix the type of a symbol created with .comm and no corresponding .type.Rafael Espindola
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119060 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-14Handle a peculiar comdat case: Creating a section with an undefinedRafael Espindola
signature symbol causes a local symbol to be created unless there is some other use of the symbol. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119026 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-14Fix warning.Rafael Espindola

2010-11-11Mark labels declared in tls sections as STT_TLS. This matches the behavior ofRafael Espindola
gas. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@118818 91177308-0d34-0410-b5e6-96231b3b80d8

2010-11-01Move EmitInstruction to MCObjectStreamer so that ELF and MachO can share it.Rafael Espindola
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@117925 91177308-0d34-0410-b5e6-96231b3b80d8

2010-10-06Make sure weak symbols are listed after the local ones.Rafael Espindola
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@115795 91177308-0d34-0410-b5e6-96231b3b80d8
2010-10-05On ELF we need to know which symbols are used in relocations to decide ifRafael Espindola
they should be in the symbol table or not. Instead of "guessing", just compute the symbol table after the relocations are known. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@115619 91177308-0d34-0410-b5e6-96231b3b80d8
2010-09-30Tiny patch for proof-of-concept cleanup of ARMAsmPrinter::EmitStartOfAsmFile()Jason W Kim
Small test for sanity check of resulting ARM .s file. Tested against -r115129. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@115133 91177308-0d34-0410-b5e6-96231b3b80d8
2010-09-29Move "local commons" to the end of .bss to match the gnu as behavior.Rafael Espindola

2010-09-25Move ELF to HasReliableSymbolDifference=true. Also take the opportunity to putRafael Espindola
symbols defined in merge sections in independent atoms. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@114786 91177308-0d34-0410-b5e6-96231b3b80d8
2010-09-22Avoid some Mach-O specific alignment being done on ELF.Rafael Espindola
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@114594 91177308-0d34-0410-b5e6-96231b3b80d8

2010-09-21Implement support for .local and its "interesting" interactions with .comm.Rafael Espindola
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@114382 91177308-0d34-0410-b5e6-96231b3b80d8
2010-09-15Add a InitSections method to the streamer interface.Rafael Espindola
The ELF implementation now creates text, data and bss to match the gnu as behavior. The text streamer still has the old MachO specific behavior since the testsuite checks that it will error when a directive is given before a setting the current section for example. A nice benefit is that -n is not required anymore when producing ELF files. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@114027 91177308-0d34-0410-b5e6-96231b3b80d8
2010-09-13Factoring and potential bug fix. The elf "flags" cannot be used as masks.Rafael Espindola
For example, setting STT_OBJECT (1) and STT_FUNC (2), should not produce a STT_SECTION (3). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@113759 91177308-0d34-0410-b5e6-96231b3b80d8
