Replace -flavor {gnu,darwin} with ld64.lld or ld.lld. llvm-svn: 325390 2018-02-17 05:16:57 +08:00			`# RUN: ld64.lld -ios_simulator_version_min 5.0 -arch x86_64 -r %s -o %t`
MachoFile should default to using subsections_via_symbols. When we parse a MachoFile, we set a number of members from the parsed file, for example, subsectionsViaSymbols. However, a number of passes, such as ObjCPass, create local copies of MachoFile and don't get the benefit of setting flags and other fields in the parser. Instead we can just give a more sensible default as the parser will definitely get the correct value from the file anyway. llvm-svn: 259426 2016-02-02 06:24:44 +08:00			`# RUN: llvm-readobj -file-headers %t \| FileCheck %s`
