Hi Jim,

Historically, any public facing documentation from ARM has been used
as source for changes in other ARM-supporting tools, like GCC. While
we mostly think about the ARM ARM and the ABI documents as kosher, the
tools docs are also used as base for features on other compilers.

I may be wrong, but I think that it would be very hard to see ARM
changing where sections go across documents or even duplicating
information just for our sake, since other tools use them, too. I
don't mean that whatever is in whatever ARM doc has to be implemented,
but the other docs could be seen as a valid source per se, sort of
"it's ok to do it that way, since ARM does it".

I'll let the ARM guys to comment about how possible it would be to
create an assembly alias document to the bundle, but I wouldn't want
to wait until that happens to implement some obvious aliases.

cheers,
