[Qemu-devel] [PATCH 00/34] tcg, target/ppc vector improvements

[Richard Henderson <richard.henderson@linaro.org>]

This implements some of the things that I talked about with Mark
this morning / yesterday.  In particular:

(0) Implement expanders for nand, nor, eqv logical operations.

(1) Implement saturating arithmetic for the tcg backend.

    While I had expanders for these, they always went to helpers.
    It's easy enough to expand byte and half-word operations for x86.
    Beyond that, 32 and 64-bit operations can be expanded with integers.

(2) Implement minmax arithmetic for the tcg backend.

    While I had integral minmax operations, I had not yet added
    any vector expanders for this.  (The integral stuff came in
    for atomic minmax.)

(3) Trivial conversions to minmax for target/arm.

(4) Patches 11-18 are identical to Mark's.

(5) Patches 19-25 implement splat and logicals for VMX and VSX.

    VSX is no more difficult than VMX for these.  It does seem to be
    just about everything that we can do for VSX at the momement.

(6) Patches 26-33 implement saturating arithmetic for VMX.

(7) Patch 34 implements minmax arithmetic for VMX.

I've tested the new operations via aarch64 guest, as that's the set
of risu test cases I've got handy.  The rest is untested so far.
