[Qemu-devel] [PATCH for-4.1 v3 00/17] tcg/ppc: Add vector opcodes

[Richard Henderson]

Changes since v2:
  * Several generic tcg patches to improve dup vs dupi vs dupm.

    In particular, if a global temp (like guest r10) is not in
    a host register, we should duplicate from memory instead of
    loading to an integer register, spilling to stack, loading
    to a vector register, and then duplicating.

  * I have more confidence that 32-bit ppc host should work
    this time around.  No testing on that front yet, but I've
    unified some code sequences with 64-bit ppc host.

  * Base altivec now supports V128 only.  Moved V64 support to
    Power7 (v2.06), which has 64-bit load/store.

  * Dropped support for 64-bit vector multiply using Power8.
    The expansion was too large compared to using integer regs.
