Unconditional loop.

In many respects the inner operations are the same as the corresponding call operations. They have the same syntax and encodings and variants and behaviors. They get passed arguments and reserve return value slots.

The only difference is, that inner operations don't create a new frame, i.e. the frame ID stays the same, and the new values on the belt are still tagged with the same ID. This means it is still possible to access all belt values, and it is still possible to retrieve values from the caller from the Scratchpad.

This is somewhat comparable to how many functional languages have no dedicated looping keyword construct, but implement looping with recursive tail calls, that just reuse and overwrite the old context. Inner doesn't overwrite the old context due to the nature of the belt, but it also doesn't create a new one.

The inner operation, in conjunktion with the rotate operation and the Scratchpad makes it possible to statically schedule and Pipelining nested loops of any depth level.

related operations: innertr, innerfl

inner(lbl off0, ops args)

operands: like Inv :

encoding: inner(off count0, count off0) , inner(off count0, count lit0, lit off0) , inner(off count0, count lit0, lit lit1, lit off0) , inner(off count0, count lit0, lit lit1, lit lit2, lit off0)
