llvm-mirror/test/MC/MachO/darwin-x86_64-diff-relocs.s
Steven Wu 315fa847c3 Force the MachO generated for Darwin to have VERSION_MIN load command 
On Darwin, it is required to stamp the object file with VERSION_MIN load
command. This commit will provide a VERSRION_MIN load command to the
MachO file that doesn't specify the version itself by inferring from
Target Triple.
