* rx.c (decode_opcode): For "MVFC PC,", use the address of the
opcode, not the address following the opcode.
(decode_opcode): RXO_branchrel is relative to the opcode's PC, not
the address following the opcode.

* mem.c (rx_mem_ptr): When invalidating the decode cache, account
for the fact that the instruction decoder never uses swapped
addresses.
2010-09-29 Nick Clifton <nickc@redhat.com>
* rx.c (decode_opcode: RXO_int): Only break out of the emulation
loop if rx_syscall() does not return a RX_STEPPED result.
2010-09-23 Kevin Buettner <kevinb@redhat.com>
* rx.c (decode_opcode): Add cycle information for RXO_smovu.

(PD, PS, PS2, GD, GS, GS2, DSZ, SSZ, S2SZ, US1, US2, OM): "opcode"
is a pointer now.
(DO_RETURN): New. We use longjmp to return an exception result.
(decode_opcode): Make opcode a pointer to the decode cache. Save
decoded opcode information and re-use. Call DO_RETURN instead of
return throughout. Remove ediv and edivu.
