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. V2: Addressing comments from Richard Henderson. Fixed corner case bug in divweu.
