sim/bfin : ChangeLog bfin-sim.c
Log message:
sim: bfin: handle large shift values with accumulator shift insns
When the shift magnitude exceeds 32 bits, the values rotate around (since
the hardware is actually a barrel shifter). So handle this edge case,
update the corresponding AV bit in ASTAT which was missing previously,
and tweak the AZ setting based on how the hardware behaves.
