| 2011-07-14 | Unfortunately several files in MC are badly violating layering rule by using | Evan Cheng | 1 | -3/+2 | |
| TargetAsmInfo, which in turn pulls in TargetRegisterInfo, etc. :-( There are other cases of violations, but this is probably the worst. This patch is but one small step towards fixing this. 500 more steps to go. :-( llvm-svn: 135131 | |||||
| 2011-05-19 | Misc code refactorings: | Rafael Espindola | 1 | -4/+4 | |
| * Remove unnecessary arguments now that ForceExpAbs is a method. * Use ForceExpAbs in EmitAbsValue. llvm-svn: 131683 | |||||
| 2011-05-01 | Simplify the handling of pcrel relocations on ELF. Now we do the right thing | Rafael Espindola | 1 | -2/+2 | |
| for all symbol differences and can drop the old EmitPCRelSymbolValue method. This also make getExprForFDESymbol on ELF equal to the one on MachO, and it can be made non-virtual. llvm-svn: 130634 | |||||

| 2011-01-13 | Model :upper16: and :lower16: as ARM specific MCTargetExpr. This is a step | Evan Cheng | 1 | -1/+4 | |
| in the right direction. It eliminated some hacks and will unblock codegen work. But it's far from being done. It doesn't reject illegal expressions, e.g. (FOO - :lower16:BAR). It also doesn't work in Thumb2 mode at all. llvm-svn: 123369 | |||||

| f: .cfi_startproc nop .cfi_endproc assembled (on ELF). llvm-svn: 121434 | |||||
| 2010-12-07 | Sorry for such a large commit. The summary is that only MachO cares about the | Rafael Espindola | 1 | -3/+1 | |
| actuall addresses in a .o file, so it is better to let the MachO writer compute it. This is good for two reasons. First, areas that shouldn't care about addresses now don't have access to it. Second, the layout of each section is independent. I should use this in a subsequent commit to speed it up. Most of the patch is just removing the section address computation. The two interesting parts are the change on how we handle padding in the end of sections and how MachO can get the address of a-b when a and b are in different sections. Since now the expression evaluation normally doesn't know the section address, it will think that a-b needs relocation and let the MachO writer know. Once it has computed the section addresses, it calls back the expression evaluation with the section addresses to resolve these expressions. The remaining problem is the handling of padding. Currently it will create a special alignment fragment at the end. Since that fragment doesn't update the alignment of the section, it needs the real address to be computed. Since now the layout will not compute a-b with a and b in different sections, the only effect that the special alignment fragment has is update the address size of the section. This can also be done by the MachO writer. llvm-svn: 121076 | |||||

| 2010-12-04 | There are two reasons why we might want to use | Rafael Espindola | 1 | -1/+1 | |
| foo = a - b .long foo instead of just .long a - b First, on darwin9 64 bits the assembler produces the wrong result. Second, if "a" is the end of the section all darwin assemblers (9, 10 and mc) will not consider a - b to be a constant but will if the dummy foo is created. Split how we handle these cases. The first one is something MC should take care of. The second one has to be handled by the caller. llvm-svn: 120889 | |||||

| 2010-12-03 | Do with uleb the same trick we now do with dwarf line/address advances. This | Rafael Espindola | 1 | -0/+10 | |

| 2010-12-03 | Try to resolve symbol differences early, and if successful create a plain | Rafael Espindola | 1 | -0/+24 | |
