// This file defines the standard builtin function database.  Users of this file
// must define the BUILTIN macro to make use of this information.
//
//===----------------------------------------------------------------------===//

// FIXME: this needs to be the full list supported by GCC.  Right now, I'm just
// adding stuff on demand.
//
// 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
//  c -> char
//  s -> short
//  i -> int
//  f -> float
//  d -> double
//  F -> constant CFString
//  . -> "...".  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
//  S  -> signed
//  U  -> unsigned
//
// Types may be postfixed with the following modifiers:
// * -> pointer
// C -> const

// The third value provided to the macro specifies information about attributes
// of the function.  Currently we have:
//  n -> nothrow
//  c -> const
