Repeated SSR configuration [enhancement] about snitch HOT 3 CLOSED

Do you have an example on when this functionality may be helpful? For most config registers, the reset value is not necessarily helpful for real streams, so you would probably set them initially anyways and then leave them unchanged for following streams.

Can you elaborate on what you mean by "normal registers"? The launch registers having side effects is intentional, and the lower-address registers having some field restrictions and being shadowed are intentional design choices, too.

As it's semantically incorrect (as mentioned in #449) to use one register as SSR and another as a regular FPR this is needless.

I meant to use ft1 as a regular FPR / normal register (or actually the compiler) and ft0 as SSR.

just for completeness: you can use some registers as SSRs and some as FPRs simultaneously; it's just that the subset of registers connected in HW to SSR datapaths (ft0, ft1, and ft2 by default) can only be switched into and out of SSR mode together, but all other FPRs continue to work as regular registers even while SSRs are enabled, so you could use ft3 and all other non-SSR registers as temporaries.
