[PATCH 2/2] disas/hppa: Show hexcode of instruction along with disassembly
Posted by deller@kernel.org 1 year ago
From: Helge Deller <deller@gmx.de>

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.
