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.
