2010-12-01ARM/MC/ELF relocation "hello world" for movw/movt.Jason W Kim
Lifted adjustFixupValue() from Darwin for sharing w ELF. Test added TODO: refactor ELFObjectWriter::RecordRelocation more. Possibly share more code with Darwin? Lots more relocations... git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@120534 91177308-0d34-0410-b5e6-96231b3b80d8

2010-11-22Refactor the ELFRelocationEntry (pull up) and move the arch-specific statics ↵Jason W Kim
to inside the class where it belongs. Next step is to rationally break apart the RecordRelocation() Probably the step will be to have 1 member function for ech slot of the ELFRelocationEntry() git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119978 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
2010-11-15Dovetail with Dan Dunbar's rework of ELFObjectWriter.Jason W Kim
Added 2 new subclasses - X86ELFObjectWriter and ARMELFObectWriter. ARM and X86 require different code for RecordRelocation(), possibly others. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119149 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-14Move the logic to decide with which symbol we produce a relocation (if any) toRafael Espindola
a central location. This also makes us a bit more compatible with gas. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119094 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-14Handle a peculiar comdat case: Creating a section with an undefinedRafael Espindola

2010-11-09Fixed version of 118639 with an extra assert to catch similar problemsRafael Espindola

2010-10-31Add support for files with more than 65280 sections. No testcase sinceRafael Espindola
it would be a bit too big :-) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@117849 91177308-0d34-0410-b5e6-96231b3b80d8
2010-10-29Be more strict on when we produce an undefined reference. In gas a file withRafael Espindola
just .type foo,@object will produce an undefined reference to foo. On the other hand, a file with just .weakref bar, foo will not. It is somewhat hard to support both in MC since both statements should create the symbols. It should be possible if we really need to by adding to the flags, but hopefully that is not necessary. With this patch we do not produce a undefined reference in any of those cases. The assembly file needs an actual use for the undefined reference to be present. This is in preparation for a patch implementing .weakref. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@117735 91177308-0d34-0410-b5e6-96231b3b80d8
