Hi Kaj,
The same problem seems to transpire from the movsf_ie pattern for the sh2a-fpu
that also have 32 bit memory instructions. So your fix also applies there.
Note that traditional sh memory move instructions can also have a length of 2
so your fix is conservative (but not more than the previous code). Shouldn't
the new 4 bytes instructions be described latter with a new memory constraint ?
