Many supported cores use the AUTOPREFETCHER_WEAK setting which tries to order loads and stores to improve streaming performance. Since significant gains were reported in http://patchwork.ozlabs.org/patch/534469/ it seems like a good idea to enable this setting too for -mcpu=generic. Since the weak model only keeps the order if it doesn't make the schedule worse, it should not impact performance adversely on cores that don't show a gain. gcc/ * config/aarch64/aarch64.c (generic_tunings): Update prefetch model.

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.
