2017-10-31 Michael Meissner <meissner@linux.vnet.ibm.com>
* builtins.def (DEF_FLOATN_BUILTIN): Change most _Float<N> and
_Float<N>X built-in functions so that the variant without the
"__builtin_" prefix is only enabled for the GNU C and Objective C
languages when they are in non-strict ANSI/ISO mode.
(DEF_EXT_LIB_FLOATN_NX_BUILTINS): Likewise.
* target.def (floatn_builtin_p): Add a target hook to control
whether _Float<N> and _Float<N>X built-in functions without the
"__builtin_" prefix are enabled, and return true for C and
Objective C in the default hook. Include langhooks.h in
targhooks.c.
* targhooks.h (default_floatn_builtin_p): Likewise.
* targhooks.c (default_floatn_builtin_p): Likewise.
* doc/tm.texi.in (TARGET_FLOATN_BUILTIN_P): Document the
floatn_builtin_p target hook.
* doc/tm.texi (TARGET_FLOATN_BUILTIN_P): Likewise.
