// Command line warning options handler.
//
//===----------------------------------------------------------------------===//
//
// This file is responsible for handling all warning options. This includes
// a number of -Wfoo options and their variants, which are driven by TableGen-
// generated data, and the special cases -pedantic, -pedantic-errors, -w,
// -Werror and -Wfatal-errors.
//
// Each warning option controls any number of actual warnings.
// Given a warning option 'foo', the following are valid:
//    -Wfoo, -Wno-foo, -Werror=foo, -Wfatal-errors=foo
//
// Remark options are also handled here, analogously, except that they are much
// simpler because a remark can't be promoted to an error.
