| 22 | /* Before including this file, you should define a macro: |
---|
| 23 | |
---|
| 24 | DEF_BUILTIN (ENUM, NAME, CLASS, TYPE, LIBTYPE, BOTH_P, |
---|
| 25 | FALLBACK_P, NONANSI_P) |
---|
| 26 | |
---|
| 27 | This macro will be called once for each builtin function. The |
---|
| 28 | ENUM will be of type `enum built_in_function', and will indicate |
---|
| 29 | which builtin function is being processed. The NAME of the builtin |
---|
| 30 | function (which will always start with `__builtin_') is a string |
---|
| 31 | literal. The CLASS is of type `enum built_in_class' and indicates |
---|
| 32 | what kind of builtin is being processed. |
---|
| 33 | |
---|
| 34 | Some builtins are actually two separate functions. For example, |
---|
| 35 | for `strcmp' there are two builtin functions; `__builtin_strcmp' |
---|
| 36 | and `strcmp' itself. Both behave identically. Other builtins |
---|
| 37 | define only the `__builtin' variant. If BOTH_P is TRUE, then this |
---|
| 38 | builtin has both variants; otherwise, it is has only the first |
---|
| 39 | variant. |
---|
| 40 | |
---|
| 41 | TYPE indicates the type of the function. The symbols correspond to |
---|
| 42 | enumerals from builtin-types.def. If BOTH_P is true, then LIBTYPE |
---|
| 43 | is the type of the non-`__builtin_' variant. Otherwise, LIBTYPE |
---|
| 44 | should be ignored. |
---|
| 45 | |
---|
| 46 | If FALLBACK_P is true then, if for some reason, the compiler cannot |
---|
| 47 | expand the builtin function directly, it will call the |
---|
| 48 | corresponding library function (which does not have the |
---|
| 49 | `__builtin_' prefix. |
---|
| 50 | |
---|
| 51 | If NONANSI_P is true, then the non-`__builtin_' variant is not an |
---|
| 52 | ANSI/ISO library function, and so we should pretend it does not |
---|
| 53 | exist when compiling in ANSI conformant mode. */ |
