[gcc]
2017-07-13  Michael Meissner  <meissner@linux.vnet.ibm.com>

	Back port from trunk
	2017-07-12  Michael Meissner  <meissner@linux.vnet.ibm.com>

	PR target/81193
	* config/rs6000/rs6000-c.c (rs6000_cpu_cpp_builtins): If GLIBC
	provides the hardware capability bits, define the macro
	__BUILTIN_CPU_SUPPORTS__.
	* config/rs6000/rs6000.c (cpu_expand_builtin): Generate a warning
	if GLIBC does not provide the hardware capability bits.  Add a
	gcc_unreachable call if the built-in cpu function is neither
	__builtin_cpu_is nor __builtin_cpu_supports.
	* doc/extend.texi (PowerPC built-in functions): Document that
	GLIBC 2.23 or newer is needed by __builtin_cpu_is and
	__builtin_cpu_supports.  Document the macros defined by GCC if the
	newer GLIBC is available.
