[PATCH 0/4] VSX 32-byte vector paired load/store instructions

[Balamuruhan S]

VSX vector paired instructions operates with octword (32-byte) operand
for loads and stores between storage and a pair of two sequential Vector-Scalar
Registers (VSRs). There are 4 word instructions and 2 prefixed instructions
that provides this 32-byte storage access operations - lxvp, lxvpx, stxvp,
stxvpx, plxvpx, pstxvpx.

Emulation infrastructure doesn't have support for these instructions, to
operate with 32-byte storage access and to operate with 2 VSX registers.
This patch series enables the instruction emulation support and adds test
cases for them respectively.

Balamuruhan S (4):
  powerpc/sstep: support new VSX vector paired storage access
    instructions
  powerpc/sstep: support emulation for vsx vector paired storage access
    instructions
  powerpc ppc-opcode: add opcodes for vsx vector paired instructions
  powerpc sstep: add testcases for vsx load/store instructions
