* builtins.c (expand_builtin_memcpy): Remove endp argument and endp != 0 handling. Pass 0 to store_by_pieces. (expand_builtin_mempcpy): Add endp argument. Don't call expand_builtin_memcpy, call store_by_pieces resp. move_by_pieces directly. If ignoring result, only do expand_call. (expand_builtin_stpcpy): Likewise. Call expand_builtin_mempcpy otherwise. (expand_builtin_strncpy, expand_builtin_memset): Adjust store_by_pices callers. (expand_builtin): Adjust expand_builtin_memcpy and expand_builtin_mempcpy callers. * expr.c (can_move_by_pieces): New function. (move_by_pieces): Add endp argument, return to resp. memory at end or one byte earlier depending on endp. (store_by_pieces): Likewise. (emit_block_move): Adjust call to move_by_pieces. (emit_push_insn): Adjust move_by_pieces caller. * expr.h (can_move_by_pieces): New prototype. (store_by_pieces): Adjust prototypes. * rtl.h (move_by_pieces): Adjust prototype. * config/mips/mips.c (expand_block_move): Adjust move_by_pieces caller. * gcc.c-torture/execute/builtins/string-4.c (main_test): Remove mempcpy test with post-increments. * gcc.c-torture/execute/string-opt-3.c: New test. * gcc.dg/string-opt-1.c: New test.

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.
