[Qemu-devel] [RISU PATCH v3 00/18] Support for generating x86 SIMD test images

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

This is v3 of the patch series posted in [1] and [2]. Note that this
is the first fully-featured patch series implementing all desired
functionality, including (V)LDMXCSR and VSIB-based instructions like
VGATHER*.

While implementing the last bits required in order to support VGATHERx
instructions, I ran into problems which required a larger redesign;
namely, there are no more !emit blocks as their functionality is now
implemented in regular !constraints blocks. Also, memory constraints
are specified in !memory blocks, similarly to other architectures.

I tested these changes on my machine; both master and slave modes work
in both 32-bit and 64-bit modes.

Cheers,
 -Jan

Changes since v2:
  Too many to be listed individually; this patch series might be
  better reviewed on its own.
