For memset, the size of used vector is decided by MIN(MOVE_MAX_PIECES, STORE_MAX_PIECES). Unless there's u-arch prefer big size vector for memcpy and small size vector for memset, there's no need to have a separate option or tune for it. In general, x86 backend always prefer big size vector for memset due to STLF issue. gcc/ChangeLog: PR target/121970 * config/i386/i386-options.cc (ix86_target_string): Remove store_max.

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.
