Michael Meissner 3787ee47fc re PR target/81193 (PowerPC GCC __builtin_cpu_is and __builtin_cpu_supports should warn about old libraries)
[gcc]
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.
	(rs6000_get_function_versions_dispatcher): Change the warning
	that an old GLIBC is used which does not export the capability
	bits to be an error.
	* doc/extend.texi (target_clones attribute): Document the
	restriction that GLIBC 2.23 or newer is needed on the PowerPC.
	(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.

This directory contains the GNU Compiler Collection (GCC).

The GNU Compiler Collection is free software.  See the files whose
names start with COPYING for copying permission.  The manuals, and
some of the runtime libraries, are under different terms; see the
individual source files for details.

The directory INSTALL contains copies of the installation information
as HTML and plain text.  The source of this information is
gcc/doc/install.texi.  The installation information includes details
of what is included in the GCC sources and what files GCC installs.

See the file gcc/doc/gcc.texi (together with other files that it
includes) for usage and porting information.  An online readable
version of the manual is in the files gcc/doc/gcc.info*.

See http://gcc.gnu.org/bugs/ for how to report bugs usefully.

Copyright years on GCC source files may be listed using range
notation, e.g., 1987-2012, indicating that every year in the range,
inclusive, is a copyrightable year that could otherwise be listed
individually.
