This was dormant for quite some time, but it started happening for me on gcc.c-torture/compile/pr65153.c sometime after r276645 for -mabi=32 linux runs. The pattern accepts any SMALL_OPERAND constant value while it asserts during the final that the value is in the mode size range. I this case it happens that combine_and_move_insns during ira makes a pattern with negative "shift count" which fails at final stage. This simple fix just truncates the constant operand to mode size the same as shift patterns. gcc/ChangeLog: 2019-11-13 Dragan Mladjenovic <dmladjenovic@wavecomp.com> * config/mips/mips.md (rotr<mode>3): Sanitize the constant argument instead of asserting its value.

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.
