define_insn *rotl<mode>3_insert_4 use mode iterator GPR which consists of SImode and conditional DImode, but the condition of this define_insn requires the mode should be SImode. By further checking, it's found that the rldimi instruction can not be used for this pattern since the required mask can not be represented correctly. We can have the fixed mask end 31 with rlwimi, but can not have the fixed mask end 63 with rldimi as it has to be (63 - SH) always. So this patch simplifies this define_insn to use SImode only. gcc/ChangeLog: * config/rs6000/rs6000.md (*rotl<mode>3_insert_4): Replace mode iterator GPR with SImode, adjust the condition and output template, rename to ... (*rotlsi3_insert_4): ... this. |

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.
