llvm-project/clang/test/Preprocessor/ptrauth_feature.c

//// Note: preprocessor features exactly match corresponding clang driver flags. However, some flags are only intended to be used in combination with other ones.
//// For example, -fptrauth-init-fini will not affect codegen without -fptrauth-calls, but the preprocessor feature would be set anyway.
