Alpha emulation structure:
cpu.h           : CPU definitions globally exported
exec.h          : CPU definitions used only for translated code execution
helper.c        : helpers that can be called either by the translated code
                  or the Qemu core, including the exception handler.
op.c            : Alpha dedicated micro-operations used by the code translator
op_helper.c     : helpers that can be called only from micro-operations
op_helper.h     : micro-operations helpers prototypes
op_helper_mem.h : micro-operations templates
                  for load and stores accesses helpers
op_mem.h        : micro-operations templates for load and stores accesses
op_template.h   : micro-operation templates for register moves
translate.c     : Alpha instructions to micro-operations translator

Code translator status:
The Alpha CPU instruction emulation should be quite complete with the
limitation that the VAX floating-point load and stores are not implemented.
The 4 MMU modes are implemented.

Linux user mode emulation status:
a few programs start to run. Most crash at a certain point, dereferencing a
NULL pointer. It seems that the UNIQUE register is not initialized properly.
It may appear that old executables, not relying on TLS support, run but
this is to be prooved...

Full system emulation status:
* Alpha PALCode emulation is in a very early stage and is not sufficient
  to run any real OS. The alpha-softmmu target is not enabled for now.
* no hardware platform description is implemented
* there might be problems in the Alpha PALCode dedicated instructions
  that would prevent to use a native PALCode image.
