Do not recurse into symbol refs that have a variant kind. This prevents us from losing the variant when producing a relocation on an alias. llvm-svn: 117037

Move the logic to decide with which symbol we produce a relocation (if any) to a central location. This also makes us a bit more compatible with gas. llvm-svn: 119094

Change MCExpr::EvaluateAsRelocatableImpl of variables to return the original 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
