[edit] Patches
JITCodeEmitter class and implementation patch file list and documentation - Applied with mods to formatting and generic parameter naming
ObjectCodeEmitter and Code Emitter patch file list and documentation
Reworked MachO code File reorganization and minor refactoring
MachO File reorganization and minor refactoring patch
[edit] Prototype DOE ObjectCodeEmitter
MachO DOE patch file list and patch documentation
MachO PowerPC tests This is the llvm/test/CodeGen/PowerPC test set adapted for the MachO backend. Its probably not a very good test set but all I could muster initially.
