jixso for fpmul_test.smt2 the bitwuzla -SE kissat I ran overnight made very little progress and now I need to reboot for updates (for fp16mul_test it was 9 times faster than z3 on my machine)07:40
programmerjakeok, as expected it's probably brute-forcing it to some extent07:41
jixyeah, even proving equivalence of different integer multipliers isn't handled very well by CDCL solvers07:46
programmerjakeif you have time, could you look at my pr to see if i made any major mistakes? i don't want to merge it yet until i have modified nmigen to use it and can verify that works...it does have a test tho so at least it works in verilog07:49
programmerjakethx!07:50
jixso far I'm much more familiar with the formal parts (smtbmc, sby and specific yosys passes) than yosys overall (which is where part of my hesitation to add a cell for this comes from) but I can have a look07:55
programmerjakethx!07:56
programmerjakeoh, should i escape the expression to avoid unintentionally producing smtbmc command comments?07:57

cr1901Updating 06ef3f264..606f1637a23:21
cr1901kernel/constids.inc                    |   12 +23:21
cr1901Ahhh, this would explain why sccache thinks nothing's up to date23:22
cr1901(I think)23:23
mwkI umm23:23
mwkI may have landed a... thing23:23
cr1901Yea, it's not a problem. I was just trying to benchmark something and now the results are gonna be thrown off :P23:24
cr1901More amused than anything that the one day I decide to do this, a new feature lands :D23:25
mwkdo what?23:25
cr1901I upgraded to an SSD after my Windoze installation died. I wanted to benchmark how fast I can build yosys on this 11 year old Core i7 laptop when the hard drive bottleneck is removed 1/223:26
cr1901with management engine on and off23:26
cr1901err not management engine23:27
cr1901Idk where my mind is tonight23:27
cr1901With MsMpEng.exe (Defender/Antivirus) turned on and off*.23:27
cr1901I git pulled thinking it wouldn't matter much, and to give a more realistic incremental build. Whoops :D23:30
mwkwelp sorry I destroyed everything23:30
cr1901No worries. You landing a new feature is far more important than my silly benchmark :3.23:31
