PR rtl-optimization/51023 * combine.c (simplify_comparison) <case SIGN_EXTEND>: Don't use val_signbit_known_clear_p for signed comparison narrowing optimization. Don't check for non-VOIDmode, use HWI_COMPUTABLE_MODE_P macro. <case ZERO_EXTEND>: Don't check for non-VOIDmode. Optimize even when const_op is equal to GET_MODE_MASK (mode), don't optimize if const_op is negative. * gcc.c-torture/execute/pr51023.c: New test. From-SVN: r181257 |

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.
