Integer constants in sub UNITS_PER_WORD modes should normally be sign
extended. Use
trunc_int_for_mode (INTVAL (operands[1]) >> 16, HImode)
and similarly for the other operand.
Incidentally, this kind of question may be better asked on
gcc@xxxxxxxxxxx, although there is nothing wrong with using gcc-help.
