# 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
|
||||
# constructor_priority for constructor attribute with priority
|
||||
# deprecated
|
||||
# destructor
|
||||
# dllexport
|
||||
# dllimport
