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
2010-11-18Change CodeGen to use .loc directives. This produces a lot more readable outputRafael Espindola
and testing is easier. A good example is the unknown-location.ll test that now can just look for ".loc 1 0 0". We also don't use a DW_LNE_set_address for every address change anymore. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119613 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
2010-11-15Fix PR8565.Rafael Espindola
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

2010-11-15add targetoperand flags for jump tables, constant pool and block addressChris Lattner
nodes to indicate when ha16/lo16 modifiers should be used. This lets us pass PowerPC/indirectbr.ll. The one annoying thing about this patch is that the MCSymbolExpr isn't expressive enough to represent ha16(label1-label2) which we need on PowerPC. I have a terrible hack in the meantime, but this will have to be revisited at some point. Last major conversion item left is global variable references. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119105 91177308-0d34-0410-b5e6-96231b3b80d8
