//===--- Builtins.def - Builtin function info database ----------*- C++ -*-===//
//
// The LLVM Compiler Infrastructure
//
// This file is distributed under the University of Illinois Open Source
// License. See LICENSE.TXT for details.
//
//===----------------------------------------------------------------------===//
//
// 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
// b -> boolean
// c -> char
// s -> short
// i -> int
// f -> float
// d -> double
// z -> size_t
// F -> constant CFString
// a -> __builtin_va_list
// V -> Vector, following num elements and a base type.
// . -> "...". 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
// & -> reference
// C -> const
// 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
// c -> const
// F -> this is a libc/libm function with a '__builtin_' prefix added.
// FIXME: gcc has nonnull
// Standard libc/libm functions:
