// Options

// The internal option ID must be a valid C++ identifier and results in a
// clang::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:
//   _ => __
//   - => _
//   # => _HASH
//   , => _COMMA
//   = => _EQ
//   C++ => CXX
//   . => _
