Post-spec optimisation, wen and where

[Simon Peyton Jones]

I’m afraid I don’t understand the question. Can you show a small test case and make your question concrete?

Hi devs,

I am wondering where the optimisation (e.g. simplified) of specialised dictionaries is taking place. In my case -ddump-spec shows unoptimised, but -ddump-simpl-iterations shows already optimised dictionaries (float-out already happened).

I searched yesterday, but to no avail.

Thanks,
