New Revision: 189305

URL: http://llvm.org/viewvc/llvm-project?rev=189305&view=rev
Log:
When ObjectFileMachO::GetModuleSpecifications is getting the ArchSpec
out of a binary, if the Mach-O binary is MH_PRELOAD ("standalone"), don't
let the OS be set to "ios" or "macosx" - there will be no dynamic loader
used when debugging this process.
