| Zoffix | Would someone with keys check all of MoarVM org's repos that have webhooks for bot commits announcements have them set up to with URL hack.p6c.org:8888/?chan=#moarvm ? I already done it for MoarVM/MoarVM, but don't have access to other repos | 12:11 | |

| Zoffix | So we got some fork of libtommath or somethin? They made second fix for expmod, how do we pull in this fix? github.com/libtom/libtommath/issue...-336654018 | 20:06 | |
| timotimo | yeah we have a libtommath repo under moarvm/ | 20:12 | |
|

| timotimo | i'm not entirely sure why we made our own fork | 20:13 | |
| Zoffix | timotimo: do I just cherry pick that commit? into that repo and moarvm will automagically use it? | 20:18 | |
| timotimo | Zoffix: looks like we literally just have the fork for the inclomplete fix for the expmod thing | ||
| Zoffix | hah | ||
| Maybe I shouldn't touch this. | |||
| timotimo | you'd also want to check out the newer commit in the submodule | 20:19 | |
| hm. another DJ just started and they got like 2x the volume compared to the previous one | |||
| Zoffix | Yeah, I remember all the issues we had with libtommath repo last time during builds. So I'm not gonna touch it, 'cause I'm a n00b. But they added a new fix to expmod and asking if it's working, so if someone could try it out and respond that'd be great: github.com/libtom/libtommath/issue...-336654018 | 20:24 | |
| Zoffix opens an Issue | 20:25 | ||
| timotimo | oh | ||
| was that libtommath, yeah? | |||
| that was when it wasn't a submodule and i turned it into one | |||
| and nobody could "git pull" because there was this mysterious "libtommath" directory that would have been overwritten with a "libtommath" directory | 20:26 | ||
| and clearly that's a no-go | |||
| Zoffix | There was alrteady issue for it. I commented there: github.com/MoarVM/MoarVM/issues/54...-336664939 | 20:27 | |
| timotimo | i got oropax (earplugs) and a power cord now | 20:32 | |
| why am i doing this on my laptop %) | 20:37 | ||
| Geth | MoarVM/master: 4 commits pushed by (Samantha McVey)++ | 20:40 | |
| samcv | getting that merged | ||
| timotimo | i'm running spectests with very latest libtommath now | 20:42 | |
| haha, they really have something called SLURM? | 20:46 | ||
| that's amazing. poznan++ | 20:48 | ||
| Zoffix | rofl | ||
| timotimo | q:to/qapla'/ actually works <³ | 20:49 | |
| er | |||
| <3 | |||
| samcv | slurm? | ||
| what is SLURM in libtommath | 20:50 | ||

| timotimo | no, it's for scheduling and such | 20:51 | |
| for clusters | |||
| Simple Linux Utility for Resource Management (SLURM) | 20:52 | ||
| i actually wrong-windowed slurm into #moarvm even though i meant it to be in #perl5 | |||
| ... | |||
| #perl6 | |||
| huh. i grabbed the newest libtommath stuff and the expmod test file now hangs? | 20:53 | ||
| oooooh | 20:54 | ||
| it's in a branch | |||
| let's try that again | 20:55 | ||
| i assume i'd have to add an extra test or two to the file which used to hang it | 20:57 | ||
| that was a bad formulation | 20:58 | ||
| mst | I was assuming it was another joke reference to Futurama | 21:01 | |
| timotimo | it probably i | 21:05 | |
| is | |||
| there's just one fudge ni the expmod file and that passes with the fixed branch of libtom | 21:07 | ||
| Zoffix | timotimo: in roast? Yeah, there's one fudge I wrote for some ticket where I spotted that it hangs with more than just `-1` for an arg (or whatever it was) | 21:08 | |
| timotimo | right | 21:09 | |
| should i systematically try lots of different arg combinations? | 21:10 | ||
| Zoffix | prolly | ||
| timotimo | i can also push The Stuff if you'd like to try yourself? | ||
| Zoffix | push | 21:11 | |
| oh wait | |||
| I don't wanna try | |||
| Just push so it's awailable for everyone :) | 21:12 | ||
| timotimo | :) | ||
| junctions ftw | |||
| expmod(any(^100), any(^100), any(^100)) | |||
| Zoffix | :D | ||
| timotimo | it prints a result | ||
| so that means it doesn't hang | |||
| it doesn't parallelize though | 21:13 | ||
| Zoffix | you didn't exercise the bug with ^100 tho | ||
| it needed negatives or something | |||
| timotimo | oh | ||
| which one? | |||
| ok now with ^1000 three times it either hangs or takes a long time, and i'm not sure which :D | 21:16 | ||
| Zoffix | m: expmod(42, -1, 7) | 21:17 | |
| camelia | (timeout) | ||
| timotimo | expmod(any(^100), -1, any(^100)) doesn't hang | 21:18 | |
| Zoffix | \o/ | 21:19 | |
| timotimo | hm. it's rather slow, but at least expmod accounts for 72.4% of total run time | 21:28 | |
| it looks like it's preventing the containing block from being jitted | |||
| it'd be trivial to jit that op | 21:29 | ||
| let's see how much faster that would make it | |||
| pff, what | 21:31 | ||
| expmod takes the result as an argument. i'd have to fix that first | |||
| damn, if we pull the repr_alloc_init out of the bigint op functions again later we can spesh them into optimized object initialization | 21:34 | ||
| don't actually wanna do it right now | 21:37 | ||
| i'd be interested to hear how far we are away from combining a spesh fact "known type" with a "call the allocate reprop" from inside an expr tree in the new jit | 21:42 | ||
