<zignig> Lofty: no you don't , sleep deprivation and a migraine is a bad combination...
<whitequark> marble: yeah
<whitequark> i usually say reset=~0 since it indicates intent a bit better
<whitequark> but for all intents and purposes it's equivalent
<whitequark> *the semantics is equivalent

<awygle> i'm surprised using -1 doesn't give you a signed shape
<whitequark> reset value doesn't affect the shape of a signal

<cr1901_modern> whitequark: What's the name of that yosys pass you developed for boneless b/c abc can handle small changes very poorly?

<anuejn> whitequark: is there any particular reason why get_ineg and get_oneg are distinct functions
<anuejn> (they are functionally equivalent in each function)
<anuejn> and is there anything that stands against factoring out a generic version of get_{i,o}neg into a util file in vendor/ ?
<vup> anuejn: ice40 seems to have some special code for get_{i,o}neg
<anuejn> i have seen that
<anuejn> but the others share a functionally equivalent version
<vup> true
hitomi2509 has quit [Quit: Nettalk6 - www.ntalk.de]
<anuejn> and is there a specific reason why the constructor of DiffPairs doesnt have invert exposed while Pins has?
