[Qemu-devel] [PATCH 0/6] target/rx: Improvements to disassembly

[Richard Henderson]

Here's a sample of the new output, taken from u-boot.bin:

IN:
0xfff8000a:  fb 12 00 01 00 00          mov.l   #0x00000100, r1
0xfff80010:  fb 32 f0 13 00 00          mov.l   #0x000013f0, r3
0xfff80016:  43 13                      sub     r1, r3
0xfff80018:  fb 22 00 ea f9 ff          mov.l   #-398848, r2
0xfff8001e:  7f 8f                      smovf
0xfff80020:  ef 01                      mov.l   r0, r1
0xfff80022:  05 1e 32 00                bsr.a   fff83240

IN:
0xfff83240:  72 11 5c fb                add     #-1188, r1
0xfff83244:  75 21 f0                   and     #-16, r1
0xfff83247:  02                         rts

Obviously there are still a few inconsistencies in the
format strings used for the immediates, but the format
is readable and it is easy to look at the opcode to see
how our decode compares to the manual.
