[gcc] 2016-12-30 Michael Meissner <meissner@linux.vnet.ibm.com> PR target/78900 * config/rs6000/rs6000.c (rs6000_split_signbit): Change some assertions. Add support for doing the signbit if the IEEE 128-bit floating point value is in a GPR. * config/rs6000/rs6000.md (Fsignbit): Delete. (signbit<mode>2_dm): Delete using <Fsignbit> and just use "wa". Update the length attribute if the value is in a GPR. (signbit<mode>2_dm_<su>ext): Add combiner pattern to eliminate the sign or zero extension instruction, since the value is always 0/1. (signbit<mode>2_dm2): Delete using <Fsignbit>. 2017-01-03 Michael Meissner <meissner@linux.vnet.ibm.com> PR target/78953 * config/rs6000/vsx.md (vsx_extract_<mode>_store_p9): If we are extracting SImode to a GPR register so that we can generate a store, limit the vector to be in a traditional Altivec register for the vextuwrx instruction.

README
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.
