qemu_plugin_insn_disas() versus -cpu

[Marc Hacin]

I am using qemu_plugin_insn_disas() in a TCG plugin.
Some floating point instructions are properly translated to host code, 
as it works in the emulator, but are translated to ".byte " by 
qemu_plugin_insn_disas().

It seems that the capstone library behind qemu_plugin_insn_disas does 
not support that PowerPC core.

But as the emulator translates right the guest code, I wonder why 
capstone is required. Isn't it possible for the translator to also build 
a string, disassembling of any guest instruction ? So as to be 
conformant with configure'd selected targets.

Or else, use of the GNU binutils code ?
I compiled using a cross GNU compiler, for that specific processor (arch 
is *gnuspe). arch-objdump is disassembling what capstone fails to do. I 
don't know if there is a clean disassembling layer in objdump, but using 
it instead of capstone may cover a larger processors set (?).
