// For zippered dylibs we expect two load commands:
// one for macos and one for maccatalyst.
//
// Note: For dylibs with deployment targets earlier than 10.14 we
// should see an LC_VERSION_MIN_MACOSX load command followed by a
// LC_BUILD_VERSION command. This enables the dylib to be back
// deployed to versions of the OS don't support macCatalyst.
//
// For dylibs targetting 10.14 and later, we should see two
// LC_BUILD_VERSION commands.
//
// CHECK-ZIPPERED:       cmd {{LC_BUILD_VERSION|LC_VERSION_MIN_MACOSX}}
// CHECK-ZIPPERED-NEXT:  cmdsize
// CHECK-ZIPPERED-NEXT:  {{platform 1|version}}

// CHECK-ZIPPERED-NEXT:  cmdsize
// CHECK-ZIPPERED-NEXT:  platform 6

// For macCatalyst-only dylibs we expect a maccatalyst load command and no macos load command

// For Mac-only dylibs we expect a macos load command and no maccatalyst load command
// Similar to the zippered case, when the deployment target is 10.14 and later
// we should expect a *single* LC_BUILD_VERSION command and when it is earlier
// we should expect only a LC_VERSION_MIN_MACOSX command.
