* Change MCExpr::EvaluateAsRelocatableImpl of variables to return the originalRafael Espindola2010-11-155-116/+60
| | | | | | | | | | | | | | | | | | | | | | | | | | 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
* Dovetail with Dan Dunbar's rework of ELFObjectWriter.Jason W Kim2010-11-151-223/+311
| | | | | | | | | | 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
* Fix PR8565.Rafael Espindola2010-11-152-6/+26
| | | | | | | | | | | This moves most of the isUsed logic to the MCSymbol itself. With this we get a bit more relaxed about allowing definitions after uses: uses that don't evaluate their argument immediately (jmp foo) are accepted. ddunbar, this was the smallest compromise I could think of that lets us accept gcc (and clang!) assembly. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119144 91177308-0d34-0410-b5e6-96231b3b80d8

* Wire up primitive support in the assembler backend for writing .o filesChris Lattner2010-11-155-1/+137
| | | | | | | | | | | | | | | | directly on the mac. This is very early, doesn't support relocations and has a terrible hack to avoid .machine from being printed, but despite that it generates an bitwise-identical-to-cctools .o file for stuff like this: define i32 @test() nounwind { ret i32 42 } I don't plan to continue pushing this forward, but if anyone else was interested in doing it, it should be really straight-forward. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119136 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | | | | | into the immediate field. This allows us to encode stuff like this: lbz r3, lo16(__ZL4init)(r4) ; globalopt.cpp:5 ; encoding: [0x88,0x64,A,A] ; fixup A - offset: 0, value: lo16(__ZL4init), kind: fixup_ppc_lo16 stw r3, lo16(__ZL1s)(r5) ; globalopt.cpp:6 ; encoding: [0x90,0x65,A,A] ; fixup A - offset: 0, value: lo16(__ZL1s), kind: fixup_ppc_lo16 With this, we should have a completely function MCCodeEmitter for PPC, wewt. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119134 91177308-0d34-0410-b5e6-96231b3b80d8
* add support for encoding the lo14 forms used for a few PPC64 addressingChris Lattner2010-11-155-25/+45
