#
# SYNOPSIS
#
# AX_GCC_FUNC_ATTRIBUTE(ATTRIBUTE)
#
# DESCRIPTION
#
# This macro checks if the compiler supports one of GCC's function
# attributes; many other compilers also provide function attributes with
# the same syntax. Compiler warnings are used to detect supported
# attributes as unsupported ones are ignored by default so quieting
# warnings when using this macro will yield false positives.
#
# The ATTRIBUTE parameter holds the name of the attribute to be checked.
#
# If ATTRIBUTE is supported define HAVE_FUNC_ATTRIBUTE_<ATTRIBUTE>.
#
# The macro caches its result in the ax_cv_have_func_attribute_<attribute>
# variable.
#
# The macro currently supports the following function attributes:
#
# alias
# aligned
# alloc_size
# always_inline
# artificial
# cold
# const
# constructor
# deprecated
# destructor
# dllexport
# dllimport
# error
# externally_visible
# flatten
# format
# format_arg
# gnu_inline
# hot
# ifunc
# leaf
# malloc
# noclone
# noinline
# nonnull
# noreturn
# nothrow
# optimize
# pure
# unused
# used
# visibility
# warning
# warn_unused_result
# weak
# weakref
#
# Unsuppored function attributes will be tested with a prototype returning
# an int and not accepting any arguments and the result of the check might
# be wrong or meaningless so use with care.
