[de62360d] | 16 | // This grammar is based on the ANSI99/11 C grammar, specifically parts of EXPRESSION and STATEMENTS, and on the C
|
---|
| 17 | // grammar by James A. Roskind, specifically parts of DECLARATIONS and EXTERNAL DEFINITIONS. While parts have been
|
---|
| 18 | // copied, important changes have been made in all sections; these changes are sufficient to constitute a new grammar.
|
---|
| 19 | // In particular, this grammar attempts to be more syntactically precise, i.e., it parses less incorrect language syntax
|
---|
| 20 | // that must be subsequently rejected by semantic checks. Nevertheless, there are still several semantic checks
|
---|
| 21 | // required and many are noted in the grammar. Finally, the grammar is extended with GCC and CFA language extensions.

[c11e31c] | 25 |
|
---|
| 26 | // The root language for this grammar is ANSI99/11 C. All of ANSI99/11 is parsed, except for:
|
---|
| 27 | //
|
---|
| 28 | // 1. designation with '=' (use ':' instead)
|
---|
| 29 | //
|
---|
[de62360d] | 30 | // Most of the syntactic extensions from ANSI90 to ANSI11 C are marked with the comment "C99/C11". This grammar also has
|
---|
| 31 | // two levels of extensions. The first extensions cover most of the GCC C extensions, except for:
|
---|
[c11e31c] | 32 | //
|
---|
[e7aed49] | 33 | // 1. designation with and without '=' (use ':' instead)
|
---|
[c0aa336] | 34 | // 2. attributes not allowed in parenthesis of declarator
|
---|
[c11e31c] | 35 | //
|
---|
[de62360d] | 36 | // All of the syntactic extensions for GCC C are marked with the comment "GCC". The second extensions are for Cforall
|
---|
| 37 | // (CFA), which fixes several of C's outstanding problems and extends C with many modern language concepts. All of the
|
---|
| 38 | // syntactic extensions for CFA C are marked with the comment "CFA". As noted above, there is one unreconcileable
|
---|
| 39 | // parsing problem between C99 and CFA with respect to designators; this is discussed in detail before the "designation"
|
---|
| 40 | // grammar rule.
