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, ATTRS, IMPLICIT)
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.
54
55 ATTRs is an attribute list as defined in builtin-attrs.def that
56 describes the attributes of this builtin function.
57
58 IMPLICIT specifies condition when the builtin can be produced by
59 compiler. For instance C90 reserves floorf function, but does not
60 define it's meaning. When user uses floorf we may assume that the
61 floorf has the meaning we expect, but we can't produce floorf by
62 simplifying floor((double)float) since the runtime need not implement
63 it. */
