* Don't truncate MachO addresses.Jim Grosbach2011-08-09
| | | | | | | | | | | | | | | | Assigned symbol addresses get truncated to 32-bits, even on 64-bit platforms. That's obviously bogus.

* Refactor MachO relocation generaration into the Target directories.Jim Grosbach2011-06-24
| | | | | | | | | | Move the target-specific RecordRelocation logic out of the generic MC MachObjectWriter and into the target-specific object writers. This allows nuking quite a bit of target knowledge from the supposedly target-independent bits in lib/MC. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@133844 91177308-0d34-0410-b5e6-96231b3b80d8

* Teach ARM/MC/ELF to handle R_ARM_JUMP24 relocation type for conditional jumps.Jason W Kim2011-02-04
| | | | | | | | | | | | | | | | | | | (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...

| | | | | | | | | - Fixed :upper16: fix up routine. It should be shifting down the top 16 bits first. - Added support for Thumb2 :lower16: and :upper16: fix up. - Added :upper16: and :lower16: relocation support to mach-o object writer. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@123424 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | IsSymbolRefDifferenceFullyResolved, it turns out this does change behavior on enough cases for x86-32 that I would rather wait a bit on it. - In practice, we will want to change this eventually because it only means we generate less relocations (it also eliminates the need for the horrible '.set' hack that Darwin requires in some places). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@122042 91177308-0d34-0410-b5e6-96231b3b80d8
