[Qemu-devel] [PATCH v2 0/8] POWER9 TCG enablements - part2

[Nikunj A Dadhania <nikunj@linux.vnet.ibm.com>]

This series contains 11 new instructions for POWER9 described in ISA3.0.

Patches:
  01-02: Changes following instructions:
      divd[u][o][.]: Divide Doubleword Signed/Unsigned
      divw[u][o][.]: Divide Word Signed/Unsigned
  03: dtstsfi[q]    : DFP Test Significance Immediate [Quad]
  04: vabsdub       : Vector Absolute Difference Unsigned Byte
      vabsduh       : Vector Absolute Difference Unsigned Halfword
      vabsduw       : Vector Absolute Difference Unsigned Word
  05: vcmpnezb[.]   : Vector Compare Not Equal or Zero Byte
      vcmpnezh[.]   : Vector Compare Not Equal or Zero Halfword
      vcmpnezw[.]   : Vector Compare Not Equal or Zero Word
  06: vslv          : Vector Shift Left Variable
  07: vsrv          : Vector Shift Right Variable
  08: extswsli      : Extend Sign Word & Shift Left Immediate

Both part1 and part2 pushed here: https://github.com/nikunjad/qemu/tree/p9-tcg

Changelog:
v1: 
* vabsu*: drop abs() and do explicit operation
* vcmpnez*: introduce etype to avoid widening/truncating
* extswsli: drop the condition check

v0:
* Introduce helpers for ISA300 ops
* vabsdu*: drop etype from implementation
* vcmpnez*: collapse the switch case
* vsrv: use reverse traversal to get rid of temporary array
* Include divd/w in this series, as part1 mostly is pushed.
