[RFC PATCH 0/1] About adding new Z extensions in ISA realization

Dear all,
I am wondering about what is the policy on adding new multilettered
extensions into the ISA realization mechanism ?

Currently we have plenty ratified exntensions left un-added, and some
of them are already being used frequently, such as the B extension
family - - namely, the zba, zbb, zbc, and zbs.

Being unsure about whether I have done it in the right way, hence I
wrote this RFC for adding those extensions.

Also, just as I have inquired on the list before, what about the vendor
extensions ? If a vendor wants to submit a vendor extensions without
reavealing the detailed sepcs, what will be examined ?

Cordially yours,
Ruinland
