[Qemu-devel] [PATCH v2 11/22] target-cris: Mirror gen_opc_pc into insn_start

[Richard Henderson]

This perhaps isn't ideal in terms of (ab)using the "pc" field
to encode both pc and ppc + delay branch state, as one has to
be aware of this when examining opcode dumps.

But it preserves existing logic, which will be good for bisection,
and it certainly does save storage space.
