// LinkerInput - The option is a linker input.
def LinkerInput : OptionFlag;

// is useful for options like -static or -dynamic which a user may always end up
// passing, even if the platform defaults to (or only supports) that option.
def NoArgumentUnused : OptionFlag;
// Unsupported - The option is unsupported, and the driver will reject command
// lines that use it.
def Unsupported : OptionFlag;
// Ignored - The option is unsupported, and the driver will silently ignore it.

// CoreOption - This is considered a "core" Clang option, available in both
// clang and clang-cl modes.

// are made available when the driver is running in CL compatibility mode.

def CC1Option : OptionFlag;
// CC1AsOption - This option should be accepted by clang -cc1as.

// If an option affects linking, but has a primary group (so Link_Group cannot
// be used), add this flag.
