[gcc]
2016-04-11  Michael Meissner  <meissner@linux.vnet.ibm.com>

	PR target/70381
	* config/rs6000/rs6000.c (rs6000_opt_masks): Disable using the
	target attribute and pragma from changing the -mfloat128
	and -mfloat128-hardware options.

	* doc/extend.texi (Additional Floating Types): Document PowerPC
	__float128 restrictions.

[libgcc]
2016-04-11  Michael Meissner  <meissner@linux.vnet.ibm.com>

	PR target/70381
	* configure.ac (powerpc*-*-linux*): Rework tests to build
	__float128 emulation routines to not depend on using #pragma GCC
	target to enable -mfloat128.
	* configure: Regnerate.

[gcc/testsuite]
2016-04-11  Michael Meissner  <meissner@linux.vnet.ibm.com>

	PR target/70381
	* gcc.target/powerpc/float128-1.c: New tests to make sure the
	__float128 emulator is built and runs.
	* gcc.target/powerpc/float128-1.c: Likewise.

This directory contains machine-specific files for the GNU C compiler.
It has a subdirectory for each basic CPU type.
The only files in this directory itself
are some .h files that pertain to particular operating systems
and are used for more than one CPU type.
