[Qemu-ppc] [PATCH 00/18] target-ppc: Base ISA V2.06 for Power7/Power8

[Tom Musta]

The QEMU emulation models for Power7 and Power8 are still missing some
of the base instructions that were introduced in Power ISA 2.06 and
even a few that were introduced prior to that.

This patch series gets these models caught up with respect to the
base 2.06 ISA.  That is, the Book I and Book II instructions for 
the branch, fixed point and floating point units will be completed
with this series.  Decimal floating point is not addressed in this
series, nor are the base ISA 2.07 changes for the Power8 model.

In some cases, existing instructions are re-implemented using common
macros, thus eliminating some redundant code.  The patch series
eliminates almost half as much code as it adds.

Additionally, some bugs in the common floating point library (softfloat)
are fixed.
