* config/rs6000/power6.md: Replace store_data_bypass_p calls with
rs6000_store_data_bypass_p in seven define_bypass directives and
in several comments.
* config/rs6000/rs6000-protos.h: Add prototype for
rs6000_store_data_bypass_p function.
* config/rs6000/rs6000.c (rs6000_store_data_bypass_p): New
function implements slightly different (rs6000-specific) semantics
than store_data_bypass_p, returning false rather than aborting
with assertion error when arguments do not satisfy the
requirements of store data bypass.
(rs6000_adjust_cost): Replace six calls of store_data_bypass_p with
rs6000_store_data_bypass_p.

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.
