pub fn fold_delta_norms(jobs: &[Job], layout: &Layout) -> Vec<Job>Expand description
The step jobs with each recurrence job whose read-outs a gated norm in place takes next carrying that norm
(DeltaNorm): the two jobs become one, the recurrence’s read-outs gated and normed where they are made. The norm’s
gate is a slot other than the read-outs’, so it is still the one the norm read. The machine runs a job with a norm
as the recurrence then the norm’s own job, so every value the step computes is the one it computed.
