This fixes minor fallout from the IOR->ADD change for rotates that I installed a little while ago. Basically the SH backend has a special pattern for setting the T register that has elements similar to a rotate. With the IOR->ADD change that pattern no longer matches and we get scan-asm failures. Fixing isn't a trivial case of just replacing IOR with ADD as the IOR->ADD change changes some of the simplifications/canonicalizations along the way. The net is we need a pattern with a slightly different structure. I've regression tested this on sh3[eb]-linux-gnu and bootstrapped sh4-linux-gnu (without a regression test). gcc/ * config/sh/sh.md (neg_zero_extract_4b): New pattern. |

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.
