| timotimo | this age-based heuristic would have made the split "benchmark" do much less nursery collections, i'd think | 13:31 | |
| hm, except that's probably something that ran 100% inside the C code, so we would have had to annotate the C code with the coalloc thing manually | 13:43 | ||

| jnthn | For those who don't pick it up elsewhere: 6guts.wordpress.com/2016/04/30/ref...d-torture/ is about MoarVM :) | 15:23 | |
| lizmat | jnthn++ | 15:41 | |
| jnthn: btw, why 13K, why not 4K for instance ? | 16:00 | ||
| jnthn | lizmat: A prime to try and bust missing things that happen in patterns. | 16:17 | |
| lizmat: Lots of stuff happens in powers of 2, so triggering GC at different points in such cycles is good. | |||
| lizmat | ok, the blog post didn't make that clear (to me, at least :-) | 16:18 | |
| jnthn | lizmat: Besides that, it's mostly a trade-off. The lower you go, the longer it takes. But also if you go really low then you miss out on the nice "is it in fromspace" heuristics. | ||
| Because stuff ends up in gen2 | |||
| mst | I sort of went "ooh, a non-regular value, that was clever" | 16:19 | |
| lizmat: the fact it was a prime was what clued me in, but then again I used to be rather fond of number theory, so I'm not expecting that to've helped everybody else | |||
| jnthn | lizmat: Yeah, I didn't really go into why that number | 16:20 | |
| lizmat | eh, but 13K is not a prime :-) | ||
| jnthn | Hah, true that :P | ||
| 13 is though :) | |||
| lizmat | m: say 13001.is-prime | 16:22 | |

| close :-) | |||
| jnthn | ;) | ||
| I've got an 11500 byte nursery one running now, and I set it off 3 hours ago and it's still working on CORE.setting :) | |||
| If I automate this I'm inclined to have it pick numbers differently each time. | 16:23 | ||
| And note which ones it picked to allow reproduction. | |||
| lizmat | yeah, sounds like a plan | ||
| specially like the comment: (In the future, we'll make this adaptive rather than a constant.) | |||
| jnthn | :) | 16:25 | |
| arnsholt | Whee, new 6guts post! \o/ | ||
| jnthn | Seems we're getting hungry here...guess I'll make some dinner :) | 16:26 | |

| dalek | MoarVM/reframe-jit: e1bcdc4 | brrt++ | src/core/ (4 files): | 18:20 | |
| MoarVM/reframe-jit: Make frames identifiable using a sequence number | |||
| MoarVM/reframe-jit: | |||
| MoarVM/reframe-jit: Because frames can now be garbage-collected, they can be moved, and | |||
| MoarVM/reframe-jit: the identity check used in the JIT will no longer work. Thus, we'd | |||
| brrt | freenode is not so lenient to dalek | ||

| the last commit kind of fixes jit-on-reframe | |||

| brrt | sorry dalek | 18:21 | |
| timotimo | "kind of" :) | 18:23 | |
| brrt | well, ok, it fixes it, as far as i know :-) | ||
| is ther e a rakudo branch for reframe? | 18:24 | ||
| timotimo | i think there's one, yeah | ||
| brrt | cool | ||
| aaargh :-( cannot invoke this object | 18:25 | ||
| possibly a JIT bug | 18:26 | ||
| hmmm | 18:27 | ||
| be back later | 18:28 | ||
| timotimo | hm, that sounds like a place where a debug_name could help | ||
| timotimo greps for stuff | |||
| yup | 18:29 | ||
| dalek | arVM: cbb6af9 | timotimo++ | src/6model/6model.c: Default invoke handler shall output the debug name |
18:45 | |
| arVM: 2f6c8c7 | timotimo++ | src/core/frame.c: invalid register kind in getdynlex shall output the kind number |
|||
| arVM: 9af346f | timotimo++ | src/6model/6model.c: cannot find method on what object? debug_name knows! |
|||
| arVM: 1ba147e | timotimo++ | src/core/frame.c: cannot invoke this object will tell debug_name now. |
|||
| arnsholt | timotimo++ # debugging help! | 18:48 | |
| timotimo | i'm glad travis doesn't complain :P | 19:13 | |
