PR optimization/13424 * expr.c (store_constructor): Revert 2003-12-03 change. * emit-rtl.c (change_address): Check also if MEM_ATTRS is set as expected before returning early. Avoid sharing RTL if they need to be changed. * config/i386/i386.c (ix86_expand_movstr): Rework rep_mov and strmov handling so that memory attributes are preserved. Don't call ix86_set_move_mem_attrs. (ix86_set_move_mem_attrs_1, ix86_set_move_mem_attrs): Removed. (ix86_expand_clrstr): Rename src argument to dst. Rework rep_stos and strset handling so that memory attributes are preserved. (ix86_expand_strlen): Pass src argument to ix86_expand_strlensi_unroll_1. Rework strlenqi_1 handling so that memory attributes are preserved. (ix86_expand_strlensi_unroll_1): Add src argument. Use change_address instead of gen_rtx_MEM. * config/i386/i386.md (strmov, strmov_singleop, rep_mov): New expanders. (strmovdi_rex64, strmovsi, strmovsi_rex64, strmovhi, strmovhi_rex64, strmovqi, strmovqi_rex64): Remove. (rep_mov*, strmov*): Prefix insn names with *.

This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the file 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.html for how to report bugs usefully.
