| # 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 | ||
