* target/rx/translate: Add missing fall through commentPhilippe Mathieu-Daudé2020-04-081-0/+1
| | | | | | | | | | | Coverity reported a missing fall through comment, add it. Fixes: e5918d7d7f0 ("target/rx: TCG translation") Reported-by: Coverity (CID 1422222 MISSING_BREAK) Suggested-by: Richard Henderson <richard.henderson@linaro.org> Signed-off-by: Philippe Mathieu-Daudé <philmd@redhat.com> Message-Id: <20200403184419.28556-1-philmd@redhat.com> Signed-off-by: Richard Henderson <richard.henderson@linaro.org>
* target/rx: Dump bytes for each insn during disassemblyRichard Henderson2020-03-191-1/+15
| | | | | | | | | | | | | | There are so many different forms of each RX instruction that it will be very useful to be able to look at the bytes to see on which path a bug may lie.

| | | | | | | | | | | | | Many of the multi-part prints have been eliminated by previous patches. Eliminate the rest of them.

| | | | | | | | | | | | | | This has consistency with prt_ri(). It loads all data before beginning output. It uses exactly one call to prt() to emit the full instruction.

* target/rx: Disassemble rx_index_addr into a stringRichard Henderson2020-03-191-99/+55Star
| | | | | | | | | | | | | We were eliding all zero indexes. It is only ld==0 that does not have an index in the instruction. This also allows us to avoid breaking the final print into multiple pieces.
