Hallo Julius:
The jump instruction l.jalr is not triggering the illegal instruction
exception when the target register is the link register (R9). I've
tested it with my modified test suite against ORPSoC V2's copy of the
or1200 core. When running under the or1ksim simulator, the exception is
correctly triggered.
The same happens with the aligned exception, when the target register is
not multiple of 4.
Are these known issues or have I missed some Verilog configuration setting?
Thanks,
rdiez
