[Qemu-devel] [PATCH 0/6] AREG0 patches v4

[Blue Swirl]

In this version, I made basic AREG0 free load/store implementations
for all targets. Only x86-64 is tested, others have probably problems,
especially 64 bit guest (Sparc64 in this case) on 32 bit hosts.

I think this should be committed as a starting point if there are no
major objections.

Blue Swirl (6):
  TCG/i386: use iargs or oargs instead of register names
  TCG/sparc: use iargs or oargs instead of register names etc
  TCG: add 5 arg helpers to def-helper.h
  Sparc: avoid AREG0 for memory access helpers
  softmmu templates: optionally pass CPUState to memory access
    functions
  Sparc: avoid AREG0 wrappers for memory access helpers
