06:13 <arigato> cfbolz: I think it's a bug that was introduced in the optresult-unroll branch (no blame)

06:15 <arigato> after the preamble, the loop is optimized by having as "inputargs" some boxes that are themselves ResOps with an earlier operation

06:15 <arigato> this fact should never be used---the loop must not be optimized by using this info, but it sometimes is

06:16 <arigato> see "def is_inputarg(" in optimizeopt/optimizer.py

06:16 <arigato> which apparently caused some optimizations to be completely disabled because they gave nonsense

06:17 <arigato> but some others like the one in issue2904 are still there, and can still give similar nonsense

06:17 <arigato> we should probably figure out a systematic way to optimize the loop with fresh arguments

10:36 <cfbolz> arigato: I am confused: I was under the impression that at the end of the preamble we do some kind of "export state" and then "import state", to make sure that this kind of thing doesn't happen. and all extra operations that are needed in the loop body should go into the short preamble

20:15 <arigato> cfbolz: export/import state: yes, except we're missing this point: we're sending to the optimizer the actual loop with input args that are not InputArgs, but that are ResOps from earlier

20:15 <cfbolz> right

20:15 <arigato> we should completely stop doing that

20:16 <cfbolz> and just invent inputargs

20:17 <arigato> we even *have* inputargs, we're just setting up the _forwarded link the wrong way for that

20:17 <arigato> of course just reversing the link explodes, I already tried naively

20:18 <cfbolz> right

20:18 <cfbolz> and then we are suddenly in the usual mess that is unroll
