* config/rs6000/rs6000-c.c (altivec_resolve_overloaded_builtin):
Add support for vec_extract on vector float, vector int, vector
short, and vector char vector types.
* config/rs6000/rs6000.c (rs6000_expand_vector_extract): Add
vector float, vector int, vector short, and vector char
optimizations on 64-bit ISA 2.07 systems for both constant and
variable element numbers.
(rs6000_split_vec_extract_var): Likewise.
* config/rs6000/vsx.md (vsx_xscvspdp_scalar2): Allow SFmode to be
Altivec registers on ISA 2.07 and above.
(vsx_extract_v4sf): Delete alternative that hard coded element 0,
which never was matched due to the split occuring before register
allocation (and the code would not have worked on little endian
systems if it did match). Allow extracts to go to the Altivec
registers if ISA 2.07 (power8). Change from using "" around the
C++ code to using {}'s.
(vsx_extract_v4sf_<mode>_load): New insn to optimize vector float
vec_extracts when the vector is in memory.
(vsx_extract_v4sf_var): New insn to optimize vector float
vec_extracts when the element number is variable on 64-bit ISA
2.07 systems.
(vsx_extract_<mode>, VSX_EXTRACT_I iterator): Add optimizations
for 64-bit ISA 2.07 as well as ISA 3.0.
(vsx_extract_<mode>_p9, VSX_EXTRACT_I iterator): Likewise.
(vsx_extract_<mode>_p8, VSX_EXTRACT_I iterator): Likewise.
(vsx_extract_<mode>_load, VSX_EXTRACT_I iterator): New insn to
optimize vector int, vector short, and vector char vec_extracts
when the vector is in memory.
(vsx_extract_<mode>_var, VSX_EXTRACT_I iterator): New insn to
optimize vector int, vector short, and vector char vec_extracts
when the element number is variable.

* gcc.target/powerpc/vec-extract-5.c: New tests to test
vec_extract for vector float, vector int, vector short, and vector
char.
* gcc.target/powerpc/vec-extract-6.c: Likewise.
* gcc.target/powerpc/vec-extract-7.c: Likewise.
* gcc.target/powerpc/vec-extract-8.c: Likewise.
* gcc.target/powerpc/vec-extract-9.c: Likewise.

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.
