[Qemu-devel] [RFC PATCH v1 00/22] reimplement (some) x86 vector instructions using tcg-gvec

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

This patch series is an early work-in-progress snapshot of my efforts
to utilize the TCG gvec infrastracture in x86 frontend. Only a handful
of instructions have been converted (those which have a direct gvec
equivalent).

The dispatch switch for the converted instructions is sort of hacked
into gen_sse; this is obviously intended for development only.
Eventually, everything that follows this switch will be removed,
along with the SSE tables and all that goes along with it.

Cheers,
  -Jan
