* Sorry for such a large commit. The summary is that only MachO cares about theRafael Espindola2010-12-071-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | actuall addresses in a .o file, so it is better to let the MachO writer compute it. This is good for two reasons. First, areas that shouldn't care about addresses now don't have access to it. Second, the layout of each section is independent. I should use this in a subsequent commit to speed it up. Most of the patch is just removing the section address computation. The two interesting parts are the change on how we handle padding in the end of sections and how MachO can get the address of a-b when a and b are in different sections. Since now the expression evaluation normally doesn't know the section address, it will think that a-b needs relocation and let the MachO writer know. Once it has computed the section addresses, it calls back the expression evaluation with the section addresses to resolve these expressions. The remaining problem is the handling of padding. Currently it will create a special alignment fragment at the end. Since that fragment doesn't update the alignment of the section, it needs the real address to be computed. Since now the layout will not compute a-b with a and b in different sections, the only effect that the special alignment fragment has is update the address size of the section. This can also be done by the MachO writer. llvm-svn: 121076

* Define generic 1, 2 and 4 byte pc relative relocations. They are commonRafael Espindola2010-11-281-1/+1
| | | | | | and at least the 4 byte one will be needed to implement the .cfi_* directives. llvm-svn: 120240
* Fix and add tests for all cases in x86 and x86_64 where gnu as implicitlyRafael Espindola2010-11-241-5/+13

| | | | | | fixes PR8659. llvm-svn: 120076
* Added support for the Mach-O .symbol_resolver directive. rdar://8673046Kevin Enderby2010-11-191-0/+1

* Change some methods in MCDwarf.cpp to be able to handle an arbitraryRafael Espindola2010-11-191-1/+4
| | | | | | | | | | | | 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. llvm-svn: 119777
* Add .loc methods to the streamer.Rafael Espindola2010-11-161-3/+0
| | | | | | | Next: Add support for the !HasDotLocAndDotFile case to the MCAsmStreamer and then switch codegen to use it. llvm-svn: 119384
* Change MCExpr::EvaluateAsRelocatableImpl of variables to return the originalRafael Espindola2010-11-151-53/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | 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. llvm-svn: 119152
