Originally discussed here:

https://github.com/riscv-collab/riscv-gnu-toolchain/issues/1200

As far as I can see (and as outlined here:
https://github.com/riscv-collab/riscv-gnu-toolchain/issues/1200#issuecommen=
t-1451965016)
the ori x0, xn, imm instruction is getting decoded as the wrong class
(INSN_CLASS_ZBC_OR_ZBKC instead of INSN_CLASS_I) and the simulator terminat=
es
with an UNHANDLED_EXTENSION message.

If any additional info is needed please let me know - thanks.
