  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.  */
