[Qemu-devel] [PATCH v2 00/26] Merge ppc32/ppc64 tcg backends

[Richard Henderson]

The ppc32 backend isn't getting much love and attention recently, with
all of the improvements coming from me into the ppc64 backend.  Let's
reduce the maint burden a bit and combine them.

This does have a few other patches that are not strictly related to the
merge of the backends, such as addition of ELFv2 support, but I think
those come naturally at the point we're merging the two other ABIs from
the 32-bit port.

Please review, and if you've got an ELFv2 system (nudge nudge), please
give it a try and make sure it works.

This is relative to some other patches I have outstanding.

Changes v1-v2:
  * mulsh_i32 typo fixed (Uli)
  * ppc32 qemu_st_i64 bug fixed
  * ppc64 boot problem Tom reported by a generic tcg optimization fix
