00:13 cheapie Conway's Game of Life on an (overclocked) RVController: https://cheapiesystems.com/media/2026-05-15%2019-09-14.webm
00:14 cheapie It's in singleplayer so I could run it faster, 10000 instructions per second instead of the 500 that it's usually set for on VE-C

13:05 pgimeno wow, that's fast-ish
13:06 pgimeno quite fast for a 10 kHz processor
13:20 turtleman joined #luanti
13:25 sfan5 I'm thinking we do need a "spawn me an async thread that only runs my own code" function
13:32 ireallyhateirc sounds helpful. Would it cover the usual asynch env APIs or more?

14:34 cheapie pgimeno: It helps that it has a bunch of extensions (including "hardware" multiply/divide support and bit manipulation), and also that RISC-V in the "I" flavor (as seen here) has way more general-purpose integer registers than even base amd64 does
14:36 cheapie I looked through what the compiler spat out (it was compiled with -O3 -march=rv32imcb_zicsr_zbkx) and while I don't think it used a good portion of these extensions, I did see it make a fair bit of use of some instructions from the Zbb portion of the B extension
14:37 cheapie Interestingly it did not any of the shift-and-add instructions from the Zba extension, but some of my other programs I compiled for it did
14:37 cheapie did not use any*

17:13 cheapie RVController has now gained another extension (A) and the file is almost 2000 lines long
17:17 sfan5 did you look at Zc
17:30 sy joined #luanti
17:38 xor_ghost joined #luanti
18:00 cheapie sfan5: Yes, I have C implemented, which implies Zca
18:02 cheapie It would also imply Zcf if I had F and Zcd if I had D, but I don't have either of those and don't really have plans to implement them either
