[Qemu-devel] [RFC PATCH v4 00/75] rewrite MMX/SSE*/AVX/AVX2 vector instruction translation

[Jan Bobek <jan.bobek@gmail.com>]

Here comes the next version of my patch series, this time v4; the
previous version can be found at [1].

This version can decode all vector instructions up to AVX2. However,
note that this does not mean all of these instructions are implemented
correctly: to achieve that, the old ad-hoc style helpers will need to
be rewritten into the style used by gvec helpers (initial effort
towards that goal can be seen in patches 65-75). There is also a
number of instructions which have not been previously implemented at
all, for which the helpers need to be written from scratch.

Cheers,
 -Jan

Changes from v3:
  - introduce disas_insn_prefix ([2])
  - rename ck_cpuid to check_cpuid ([3])
  - clarify this series deals with vector instructions only ([4])
  - add a list of instructions per each vector ISA extension ([5])
  - change return type of check_cpuid and insnop_init to bool ([6])
