// RUN: %check_clang_tidy %s bugprone-suspicious-semicolon %t -- -- -fno-objc-arc -fobjc-abi-version=1

// This test ensures check_clang_tidy.py allows disabling Objective-C ARC and
// Objective-C 2.0 via passing arguments after -- on the command line.
//
// (We could include a test which doesn't pass any arguments after --
// to check if ARC and ObjC 2.0 are disabled by default, but that test
// could change behavior based on the default Objective-C runtime for
// the platform, which would make this test flaky.)
