Raise illegal instruction exception when l.ror is not implemented
Instead of throwing an illegal instruction exception when the rotate
instructions are disabled (OR1200_ALU_IMPL_ROTATE is undefined), another
instruction (slr?) was executed instead.
This closes bug 97

Execute trapped instruction after breakpoint is removed
Closes bug #104
When the instruction replaced by a trap instruction is restored by the
debugger, this instruction is not executed.
Proposed solution:
- Checked for a debug unstall condition plus a trap condition in
or1200_du(dbg_stall && |except_stop).
- Then, when this event occur, flush the entire pipeline (in or1200_ctrl) and
set the pc to npc in or1200_genpc(which is equal to the trapped instruction
address).

or1200_genpc: fix ipcu_cycstb_o generation
In some circumstances the CPU is still waiting for the lsu to finish
while in a pre branch state. However, ipcu_cycstb_o is set and the cycle
starts with the wrong address on the iwb bus (the one before the
branched address).
This fixes this issue.

or1200: Fix for cache bug related to first_{hit|miss}_ack
Under certain circumstances, when first_hit_ack and
first_miss_ack is asserted at the same time, cache data
would wrongly be overwritten with bus data.

or1200: l.lws support
Using the l.lws instruction doesn't work currently.
It simply skips the instruction. No exception or reaction.
The patch attached simply duplicates the behaviour of
l.lwz for l.lws.

OR1200 debug unit: prevent deadlock when trap instruction stalls
As per mailing list post <20120925160925.5725e06f@latmask.vernier.se>,
the debug unit could deadlock with the instruction decoder if the trap
instruction is held back by a pipeline stall. This change prevents that.
The problem can be reproduced by placing a breakpoint at an unfavorable
position with instruction cache enabled. In our test, this occurred
with or1200-cbasic when placing a breakpoint at test_bss using gdb, but
this is dependent on such factors as cache parameters and compilation
result. |
