+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_helper.c     : helpers that can be called only from TCG
+helper.h        : TCG helpers prototypes
+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 tested.
+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 proved...
+
+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.
