//
// This file defines the analyzer options avaible with -analyzer-config.
//
// This file is in part intended for method generation. If it's not included
// for that purpose, the following function-like macros should be predefined,
// through which all registered options are accessible:
//
// * ANALYZER_OPTION: Register a new option.
// * ANALYZER_OPTION_DEPENDS_ON_USER_MODE: Register a new option, default
// value depends on the "user-mode" option.
//
// Options where a simple getter method is sufficient are registered with the
// following macros:
//
// * ANALYZER_OPTION_GEN_FN: Register a new option, and generate a getter
// method for it in AnalyzerOptions.
//
// * ANALYZER_OPTION_GEN_FN_DEPENDS_ON_USER_MODE: Same as above, but
// generates a getter function that depends on the "user-mode" option.
//
// You can only include this file when both or none of the above two macros
// are defined!
// When they are defined, entries that do not generate functions won't appear,
// and when they aren't, all entries are converted to ANALYZER_OPTION or to
// ANALYZER_OPTION_DEPENDS_ON_USER_MODE.
