10 // This file defines the language options. Users of this file must
11 // define the LANGOPT macro to make use of this information.
13 // Optionally, the user may also define:
15 // BENIGN_LANGOPT: for options that don't affect the construction of the AST in
16 // any way (that is, the value can be different between an implicit module
17 // and the user of that module).
19 // COMPATIBLE_LANGOPT: for options that affect the construction of the AST in
20 // a way that doesn't prevent interoperability (that is, the value can be
21 // different between an explicit module and the user of that module).
23 // ENUM_LANGOPT: for options that have enumeration, rather than unsigned, type.
25 // VALUE_LANGOPT: for options that describe a value rather than a flag.
27 // BENIGN_ENUM_LANGOPT, COMPATIBLE_ENUM_LANGOPT: combinations of the above.
29 // FIXME: Clients should be able to more easily select whether they want
30 // different levels of compatibility versus how to handle different kinds
