Previously users of mulsidi_600 and umulsidi_600 had to take care of moving the multiplication result into the final destination themselves (from the MUL64_OUT_REG register). This commit converts these two instruction patterns into insn_and_split patterns that now take the final destination as an extra operand. The insn_and_split patterns generate the multiplication using two new multiplication instruction patterns, then generate the move of the result from the MUL64_OUT_REG register into the final destination. This is a clean up commit, there should be no user visible changes after this commit. 2016-12-16 Claudiu Zissulescu <claziss@synopsys.com> * config/arc/arc.md (mulsidi_600): Change to insn_and_split, generate new mul64 insn for core multiplication work. (umulsidi_600): Likewise, but use mulu64 insn. (mul64): New pattern, content taken from old mulsidi_600 insn pattern. (mulu64): Likewise, but using umulsidi_600. (mulsidi3): Remove move to destination, this is now handled by mulsidi_600 insn_and_split. (umulsidi3): Likewise, but using umulsidi_600. From-SVN: r243741 |

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.
