--- Comment #13 from Dmitry Selyutin <ghostmansd at gmail.com> ---
So, to summarize:
0. Only disassembly. I reserve the right to prepare some ground for assembly,
you already saw, but I don't promise assembly (it's even outside of the tasks
description).
1. Vanilla 32-bit instructions, but only those we have in openpower-isa. I
assume all operands, all names, etc.
2. No SVP64 yet. No sooner than we have some format for fields. I'm tired of
editing it in two places, and the third one will likely lead me to a suicide.
3. No nifty extensions whatsoever.
4. Code will follow binutils logic mostly. All optimizations beyond are likely
to be done later.
