The j options in the MPC compiler are all unsupported options. There
is no garantee that they will always remain.  There are put into the
compiler for a number of reason's some for us to understand specific
issues about code generation and some in response to requests from
customers for a specific feature or option. I just checked the compiler
sources and j7 is still there. The internal name is NoBSR and it was put
into the compiler in response to Dana Raymonds request and it is used by
us to establish an absolute limit as to the amount of optimization that
can be done. (No BSR code generation but the rest of the generated code
is the same)
