[Qemu-devel] [RFC PATCH v3 00/46] rewrite MMX/SSE/SSE2/SSE3 instruction translation

[Jan Bobek]

The previous version can be found at [1]. Changes compared to v2:

  - Expanded the instruction operand infrastructure a bit; I am now
    fairly confident that it is powerful enough to accommodate for all
    the use cases I will need. It's still a bit clunky to work with at
    times, but I am happy with it for now.

  - Reduced the number of various INSN_* (now called OPCODE_*) macro
    variants using variadic macros.

  - Implemented translation for instructions up to SSE3.

Cheers,
 -Jan
