From 98cfb53af473d10bedf3cdc8d4cc62497d086186 Mon Sep 17 00:00:00 2001 From: Greg Clayton Date: Tue, 20 Jul 2010 22:36:00 +0000 Subject: 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. git-svn-id:
