PR middle-end/50161 * simplify-rtx.c (simplify_const_unary_operation): If op is CONST_INT, don't look at op_mode, but use instead mode. * optabs.c (add_equal_note): For FFS, CLZ, CTZ, CLRSB, POPCOUNT, PARITY and BSWAP use operand mode for operation and TRUNCATE/ZERO_EXTEND if needed. * doc/rtl.texi (ffs, clrsb, clz, ctz, popcount, parity, bswap): Document that operand mode must be same as operation mode, or VOIDmode. * config/avr/avr.md (paritysi2, *parityqihi2.libgcc, *paritysihi2.libgcc, popcountsi2, *popcountsi2.libgcc, *popcountqihi2.libgcc, clzsi2, *clzsihi2.libgcc, ctzsi2, *ctzsihi2.libgcc, ffssi2, *ffssihi2.libgcc): For unary ops use the mode of operand for the operation and add truncate or zero_extend around if needed. * config/c6x/c6x.md (ctzdi2): Likewise. * config/bfin/bfin.md (clrsbsi2, signbitssi2): Likewise. * gcc.dg/pr50161.c: New test.

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.
