New Revision: 108953
URL: http://llvm.org/viewvc/llvm-project?rev=108953&view=rev
Log:
Added support to MachO.h for many defines and structures that are needed
to Parse mach-o files. All defines have been renamed to not conflict with
#defines in mach header files, all structures were left named the same but
are in the llvm::MachO namespace.
