11:41 Geth ¦ MoarVM:
11:41 Geth ¦ MoarVM: They didn't go through the normalizer due being automatically in
11:41 Geth ¦ MoarVM: NFG. This meant they missed out on \r\n -> \n translation.

16:24 jnthn eveo: ^^
16:24 eveo jnthn++ thanks
16:25 jnthn Pretty nice changelog this month :)
17:30 timotimo i read on reddit that some changes that would make I/O faster were going to be kept until the next release?
17:41 * jnthn wonders what changes those are :P
17:42 jnthn I mean, it's true in so far as more improvements are possible
17:42 jnthn But it's not like we've anything sat in unmerged branches
17:43 jnthn There was no intentional "we'll hold this back just in case", though :)
17:52 * jnthn found http://www.tomshardware.com/news/intel-mesh-architecture-skylake-x-hedt,34806.html an interesting read

18:27 jnthn bah
18:27 jnthn *site :P
18:27 jnthn I hope there's less typos in the updates
18:31 timotimo can you figure out why the benches ain't updating any more?
18:52 dogbert17_ joined #moarvm
19:30 lizmat timotimo: perhaps it was me on the mailing list
20:00 timotimo ah, yes! it was on the mailing list!
20:06 lizmat which I wrote while being under the impression of what I wrote  :-)
20:06 jnthn timotimo: Hm, think I saw what's wrong and fixed it. Guess we find out tonight :)
21:40 mj41 joined #moarvm
21:44 mj41 jnthn: Ahoj. I just noticed this regression https://gist.github.com/mj41/20c70566564283151714/revisions#diff-39859e34161f0cb6f5f50974282a2593L135
21:44 mj41 https://gist.github.com/mj41/20c70566564283151714/revisions#diff-39859e34161f0cb6f5f50974282a2593L4
21:46 mj41 also bad with disabled JIT https://gist.github.com/mj41/20c70566564283151714/revisions#diff-39859e34161f0cb6f5f50974282a2593L107
21:47 mj41 But you probably know :-). So happy hacking. I will retest after work is done.
21:47 mj41 Dobrou noc.
21:47 jnthn mj41: Diky moc :)
21:47 jnthn mj41: I'm aware there's a regression on output; I've got a plan for solving it, but didn't get to it yet :)
21:47 jnthn Thanks for supplying data on the magnitude though.
21:47 jnthn It's a bit worse than I'd thought
21:57 mj41 In this case it make sense https://gist.github.com/mj41/6761c021135ae1cb17f9#file-gistfile1-txt-L138
21:58 mj41 It's weird from my amateur point of view that it is somehow related to the loop without output inside. See https://gist.github.com/mj41/20c70566564283151714#file-gistfile1-txt-L223
22:01 mj41 But my part is done. Will backlog tomorrow :-).
22:04 mj41 Díky moc za všechnu tu práci. Dobrou.
22:05 jnthn :-)
22:05 jnthn Dobrou noc o/
23:03 timotimo that loop mj whipped up is being treated the worst way we can
23:04 timotimo for example, in order to do the comparison, we box the int and then compare. then we create a p6bool from the result which we then immediately unbox_i again to check the result value
23:05 timotimo there's also an attempt being made to sink something
23:07 timotimo the $i is passed as an intlexref to the + operator
23:08 timotimo there's 5.9k GC runs
23:08 timotimo all of them about 0.9 miliseconds long, as they don't promote a single byte
23:10 * timotimo goes to bed
