* Teach ARM/MC/ELF to handle R_ARM_JUMP24 relocation type for conditional jumps.Jason W Kim2011-02-041-1/+2
| | | | | | | | | | | | | | | | | | | (yes, this is different from R_ARM_CALL) - Adds a new method getARMBranchTargetOpValue() which handles the necessary distinction between the conditional and unconditional br/bl needed for ARM/ELF At least for ARM mode, the needed fixup for conditional versus unconditional br/bl is identical, but the ARM docs and existing ARM tools expect this reloc type...

* Sorry for such a large commit. The summary is that only MachO cares about theRafael Espindola2010-12-071-16/+85
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@121076 91177308-0d34-0410-b5e6-96231b3b80d8
