// This file defines the standard builtin function database.  Users of this file

// FIXME: This should really be a .td file, but that requires modifying tblgen.
// Perhaps tblgen should have plugins.

// The first value provided to the macro specifies the function name of the
// builtin, and results in a clang::builtin::BIXX enum value for XX.

// The second value provided to the macro specifies the type of the function
// (result value, then each argument) as follows:
//  v -> void
//  b -> boolean
//  c -> char
//  s -> short
//  i -> int
//  f -> float
//  d -> double
//  z -> size_t
//  F -> constant CFString
//  a -> __builtin_va_list
//  A -> "reference" to __builtin_va_list
//  V -> Vector, following num elements and a base type.
//  X -> _Complex, followed by the base type.
//  P -> FILE
//  J -> jmp_buf
//  SJ -> sigjmp_buf
//  . -> "...".  This may only occur at the end of the function list.
//
// Types maybe prefixed with the following modifiers:
//  L   -> long (e.g. Li for 'long int')
//  LL  -> long long
//  LLL -> __int128_t (e.g. LLLi)
//  S   -> signed
//  U   -> unsigned
//
// Types may be postfixed with the following modifiers:
// * -> pointer (optionally followed by an address space number)
// & -> reference (optionally followed by an address space number)
// C -> const
// D -> volatile

// The third value provided to the macro specifies information about attributes
// of the function.  These must be kept in sync with the predicates in the
// Builtin::Context class.  Currently we have:
//  n -> nothrow
//  r -> noreturn
//  c -> const
//  F -> this is a libc/libm function with a '__builtin_' prefix added.
//  f -> this is a libc/libm function without the '__builtin_' prefix. It can
//       be followed by ':headername:' to state which header this function
//       comes from.
//  p:N: -> this is a printf-like function whose Nth argument is the format
//          string.
//  P:N: -> similar to the p:N: attribute, but the function is like vprintf
//          in that it accepts its arguments as a va_list rather than
//          through an ellipsis
//  s:N: -> this is a scanf-like function whose Nth argument is the format
//          string.
//  S:N: -> similar to the s:N: attribute, but the function is like vscanf
//          in that it accepts its arguments as a va_list rather than
//          through an ellipsis
//  e -> const, but only when -fmath-errno=0
//  FIXME: gcc has nonnull
