# 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
