/* Before including this file, you should define a macro:
|
|
|
|
DEF_BUILTIN (ENUM, NAME, CLASS, TYPE, LIBTYPE, BOTH_P,
|
|
FALLBACK_P, NONANSI_P)
|
|
|
|
This macro will be called once for each builtin function. The
|
|
ENUM will be of type `enum built_in_function', and will indicate
|
|
which builtin function is being processed. The NAME of the builtin
|
|
function (which will always start with `__builtin_') is a string
|
|
literal. The CLASS is of type `enum built_in_class' and indicates
|
|
what kind of builtin is being processed.
|
|
|
|
Some builtins are actually two separate functions. For example,
|
|
for `strcmp' there are two builtin functions; `__builtin_strcmp'
|
|
and `strcmp' itself. Both behave identically. Other builtins
|
|
define only the `__builtin' variant. If BOTH_P is TRUE, then this
|
|
builtin has both variants; otherwise, it is has only the first
|
|
variant.
|
|
|
|
TYPE indicates the type of the function. The symbols correspond to
|
|
enumerals from builtin-types.def. If BOTH_P is true, then LIBTYPE
|
|
is the type of the non-`__builtin_' variant. Otherwise, LIBTYPE
|
|
should be ignored.
|
|
|
|
If FALLBACK_P is true then, if for some reason, the compiler cannot
|
|
expand the builtin function directly, it will call the
|
|
corresponding library function (which does not have the
|
|
`__builtin_' prefix.
|
|
|
|
If NONANSI_P is true, then the non-`__builtin_' variant is not an
|
|
ANSI/ISO library function, and so we should pretend it does not
|
|
exist when compiling in ANSI conformant mode. */
