Subject: [PATCH] disas/hppa: Show hexcode of instruction along with
|
||
|
|
disassembly
|
||
|
|
|
||
|
|
cherry picked from 2f926bfd5b79e6219ae65a1e530b38f37d62b384
|

|
|
|
||
|
|
On hppa many instructions can be expressed by different bytecodes.
|
||
|
|
To be able to debug qemu translation bugs it's therefore necessary to see the
|
||
|
|
currently executed byte codes without the need to lookup the sequence without
|
||
|
|
the full executable.
|
||
|
|
With this patch the instruction byte code is shown beside the disassembly.
