[Qemu-devel] [PATCH v5 00/16] tcg/ppc: Add vector opcodes

[Aleksandar Markovic]

From: Aleksandar Markovic <address@hidden>

Changes since v4:
  * Patch 1, "tcg/ppc: Introduce Altivec registers", is divided into
    ten smaller patches.
  * The net result (code-wise) is not changed between former patch 1
    and ten new patches.
  * Remaining (2-7) patches from v4 are applied verbatim.
  * This means that code-wise v5 and v4 do not differ.
  * v5 is devised to help debugging, and to better organize the code.

Changes since v3:
  * Add support for bitsel, with the vsx xxsel insn.
  * Rely on the new relocation overflow handling, so
    we don't require 3 insns for a vector load.

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.
