2010-11-15Fix compiler warnigns.Benjamin Kramer
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119175 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
2010-11-15correct the fixup comment printer to work on big endian platforms.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119122 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
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
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

2010-11-12MCELF: Copy the symbol name only if we're going to modify it.Benjamin Kramer

2010-11-12Remove what looks like dead code in the production of debug lines.Rafael Espindola
We only produce debug line information if we have seen a line directive, so this code is dead. Also, if we want to be bug by bug compatible with gas and sometimes produce "empty" .debug_line sections, this will match the content produced by gas. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@118914 91177308-0d34-0410-b5e6-96231b3b80d8

a weakref is used with a VariantKind. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@118798 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-11Fix the symbol index of weak references. Also make RecordRelocation a bitRafael Espindola
easier to read by having const references to the symbol, aliased symbol and renamed symbol. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@118793 91177308-0d34-0410-b5e6-96231b3b80d8

2010-11-10Update ARMConstantPoolValue to not use a modifier string. Use an explicitJim Grosbach
VariantKind marker to indicate the additional information necessary. Update MC to handle the new Kinds. rdar://8647623 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@118671 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-09Fixed version of 118639 with an extra assert to catch similar problemsRafael Espindola
earlier. Implicit bool -> int conversions are evil! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@118651 91177308-0d34-0410-b5e6-96231b3b80d8

2010-11-07Speed up AddSectionToTheEnd. It was walking all fragments in all sections.Rafael Espindola
This is really slow with we have 1000s of sections each with a corresponding relocation section. Also, it is only used by the ELF writer to add basic data, so there is no need to force a new layout pass. Should fix PR8563. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@118377 91177308-0d34-0410-b5e6-96231b3b80d8
