--- Comment #3 from Jakub Jelinek <jakub at gcc dot gnu.org> 2011-08-23 15:51:55 UTC --- Author: jakub Date: Tue Aug 23 15:51:45 2011 New Revision: 177991 URL: http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=177991 Log: 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.
