// Flags

// The option should be accepted by swift -frontend.
def FrontendOption : OptionFlag;

// The option should be accepted by swift-autolink-extract
def AutolinkExtractOption : OptionFlag;

// The option should be accepted by swift -modulewrap
def ModuleWrapOption : OptionFlag;

// The option should not be accepted by the driver.
def NoDriverOption : OptionFlag;

// Some options should not be available depending on whether this is the
// interactive driver 'swift', or the aot compiler 'swiftc'.
def NoInteractiveOption : OptionFlag;
def NoBatchOption : OptionFlag;

// The option should not force a full rebuild if added, changed, or removed.
def DoesNotAffectIncrementalBuild : OptionFlag;

// The option's argument is a file-system path that may be affected by the
// current working directory.
def ArgumentIsPath : OptionFlag;

// The option should be written into a .swiftinterface module interface file,
// and read/parsed from there when reconstituting a .swiftmodule from it.
def ModuleInterfaceOption : OptionFlag;

// The option should be written into a .swiftinterface module interface file,
// and read/parsed from there when reconstituting a .swiftmodule from it.
// The option can be safely ignored by the older compiler.
def ModuleInterfaceOptionIgnorable : OptionFlag;

// The option causes the output of a supplementary output, or is the path option
// for a supplementary output. E.g., `-emit-module` and `-emit-module-path`.
def SupplementaryOutput : OptionFlag;

// The option should be accepted by swift-symbolgraph-extract.
def SwiftSymbolGraphExtractOption : OptionFlag;

// The option should be accepted by swift-synthesize-interface.
def SwiftSynthesizeInterfaceOption : OptionFlag;

// The option should be accepted by swift-api-digester.
def SwiftAPIDigesterOption : OptionFlag;

// The option only functions in the new driver.
def NewDriverOnlyOption : OptionFlag;

// The option's argument is a path to a file that contains a list of files.
def ArgumentIsFileList : OptionFlag;

// The option that is cache invariant. Change this option doesn't affect the
// content of any output file. The candidates are options like: `-o` which only
// affects the location of the output file, or `-emit-module` which defines
// which action is performed.
def CacheInvariant : OptionFlag;

/////////
// Options

// The internal option ID must be a valid C++ identifier and results in a
// swift::driver::options::OPT_XX enum constant for XX.
//
// We want to unambiguously be able to refer to options from the driver source
// code, for this reason the option name is mangled into an ID. This mangling
// isn't guaranteed to have an inverse, but for practical purposes it does.
//
// The mangling scheme is to ignore the leading '-', and perform the following
// substitutions:
//   _ => __
//   - => _
//   / => _SLASH
//   # => _HASH
//   ? => _QUESTION
//   , => _COMMA
//   = => _EQ
//   C++ => CXX
//   . => _
