--- Comment #10 from paulus at ozlabs.org ---
Comments from IBM architects about LS010:

* Attempts to redefine “Reserved” more strictly for scope of SimpleV, which
won’t be popular.
* Also seems to redefine bit/byte/element order compared to existing
  This will be unacceptable except possibly within the confines of the SimpleV
* Cross references that would make this comprehensible seem challenging.
* Same comments as the other SimpleV component RFCs.

The successful (with respect to being accepted as an architecture extension)
combined RFC must have an organized flow to the description and must be defined
from primitive concepts understood by the existing architecture or must define
the concepts (e.g., not depend on references to other architectures or
documentation). It must completely describe changes required in the non-SimpleV
chapters to mate up with what’s going on in the new chapter. A significant part
of this is to describe all of the changes to the sequential execution model and
the interrupt chapter as grafts into the existing chapters.
