[PATCH] rx: allow cmpstrnsi len to be zero
The SCMPU instruction doesn't change the C and Z flags when the
incoming length is zero, which means the insn will produce a
value based upon the existing flag values.
As a quick kludge, adjust these flags to ensure a zero result in this
case.
gcc/
* config/rx/rx.md (rx_cmpstrn): Correctly handle len=0 case.
