Hi,
You may find it useful to enable logging of TCG ops generated with '-d
op', as well as input and output assembly with '-d in_asm,out_asm'. '-D
<filename>' could be useful to output log to a file. Here are references
to documentation: http://qemu.weilnetz.de/qemu-doc.html#index-_002dd and
http://qemu.weilnetz.de/qemu-doc.html#index-_002dD.
Best,
Sergey
