# SYNOPSIS
#
# AX_GCC_BUILTIN(BUILTIN)
#
# DESCRIPTION
#
# This macro checks if the compiler supports one of GCC's built-in
# functions; many other compilers also provide those same built-ins.
#
# The BUILTIN parameter is the name of the built-in function.
#
# If BUILTIN is supported define HAVE_<BUILTIN>. Keep in mind that since
# builtins usually start with two underscores they will be copied over
# into the HAVE_<BUILTIN> definition (e.g. HAVE___BUILTIN_EXPECT for
# __builtin_expect()).
#
# The macro caches its result in the ax_cv_have_<BUILTIN> variable (e.g.
# ax_cv_have___builtin_expect).
#
# The macro currently supports the following built-in functions:
#
# __builtin_assume_aligned
# __builtin_bswap16
# __builtin_bswap32
# __builtin_bswap64
# __builtin_choose_expr
# __builtin___clear_cache
# __builtin_clrsb
# __builtin_clrsbl
# __builtin_clrsbll
# __builtin_clz
# __builtin_clzl
# __builtin_clzll
# __builtin_complex
# __builtin_constant_p
# __builtin_ctz
# __builtin_ctzl
# __builtin_ctzll
# __builtin_expect

# __builtin_powi
# __builtin_powif
# __builtin_powil
# __builtin_prefetch
# __builtin_trap
# __builtin_types_compatible_p
# __builtin_unreachable
#
# Unsuppored built-ins will be tested with an empty parameter set and the
# result of the check might be wrong or meaningless so use with care.
