| MasterDuke | jnthn: if you've got a couple spare minutes sometime (hopefully today) i'd appreciate a look at github.com/MoarVM/MoarVM/pull/1308 | 10:09 | |
| nwc10 | could someone who knows how to test the debugserver have a look at the first commit of my pull request (#1307) and if that one is good, merge that one? The other two are (I feel) "contraversial" but the first removes a bunch of inefficiencies | ||
| MasterDuke | the nqp and rakudo builds are currently a bit panicky and that fixes it, but confirmation that it's correct and complete would be good | 10:10 | |
| nwc10 | jnthn: you're popular :-) | 10:11 | |
| MasterDuke | that's the problem with being good at your job | ||
| nwc10 is deep somewhere in $ork invovling images | |||

| MasterDuke | brrt: ahoy. btw, there have been a couple questions recently about what it would take to support the jit on arm. is it tricky work? or relatively straightforward grunt work? any difference if it's just AArch64? | 11:24 | |
| brrt | MasterDuke: I'd think there would be a good part messy work involved | 11:25 | |
| I think it ought to be possible but not necessarily easy | |||
| especially the 'legacy' JIT is very heavy on x86-isms | |||
| MasterDuke | ok, good to know | ||
| lizmat | brrt so would it make sense to start a different JIT effort for ARM > | 11:36 | |
| ? | |||
|

| brrt | not sure I'd say that either | 11:39 | |

| lizmat | well, with the next gen of Apple hardware being ARM again... I'd hate to have to run Raku on that without JIT :-) | 11:39 | |
| brrt | lizmat: on a pure technical ground, I think somebody (me?) should probably fix the legacy JIT not to suck, or to be removed altogether | 11:40 | |
| On the other hand, that someone should probably have possession of a good ARM hackmachine, and since I'm not buying apple... :-P | |||
| timotimo | lazy initialization of lookup hashes in static frames sounds like something we'd want to either lock or make access atomic for | ||
| lizmat | hehe... well, I don't have an ARM either | 11:41 | |
| and for me personally, I doubt that my next notebook will be an Apple, as Catalina managed to completely mess up just about all of my private media workflows | |||
| brrt | I'm far too satisfied with my linux thinkpad | 11:43 | |
| Ironically I got myself 32gb to be able to use gradle+intellij... now I still have to use gradle but rarely use intellij, so I hardly ever use that much memory | 11:45 | ||
| timotimo | any additional ram makes the disk faster, though i assume you have an SSD which is already pretty fast even with cold caches | 11:50 | |
| brrt | It came with an NVMe which has windows on it, and I placed an SSD into the expansion slot | 11:52 | |
| on which I installed fedora | |||
| xiaomiao | pro tip: swap on nvme is fast enough | 12:01 | |
| brrt | yeah, but it still has windows on there | ||
| which is handy in a pinch | 12:02 | ||
| xiaomiao | put the windows in a VM ;) | ||
| brrt | could, but won't :-) | 12:03 | |
| xiaomiao | me neither, waste of diskspace | 12:05 | |
| the "windows 10" tech demo my thinkpad came with still needs a few years of development before it's useful | |||
| jnthn | brrt: I figure, so far as the JIT goes, transitioning completely to using the expr JIT would make things easier so far as porting goes? | 12:06 | |
| brrt | jnthn: yes; which, unfortunately, means that someone needs to hacking work to make the expression JIT more complete still | 12:07 | |
| of which I have a bunch of half-finished branches | |||
| jnthn | brrt: I guess the good news is that dispatch is going to get a bit more regular... :) | 12:10 | |
| brrt | I think I saw bits and pieces there | 12:12 | |
| :-) | |||

| nine | MasterDuke: I think with timotimo++'s insight into spesh facts, we can merge your GC fixing PR in good conscience. | 12:38 | |
| MasterDuke | cool. then i'll do that now and bump nqp+rakudo | 12:39 | |
| Geth | MoarVM: 1a46b0ae7c | (Daniel Green)++ | src/spesh/optimize.c Maybe fix MVM_panic from entering GC during spesh The `MVM_gc_mark_thread_(un)blocked(tc)` calls were incorrect and caused `MoarVM panic: Must not GC when in the specializer/JIT` at random times. However, just removing them changed to causing `MoarVM panic: Invalid owner in item added to GC worklist`. Setting `MVM_GC_DEBUG` to `3` would reliably trigger the panic when building NQP. Removing overwriting the spesh facts fixed this, but I'm not 100% that the rest of the code is 100% correct. |
12:41 | |
| MoarVM: af1475ec15 | (Daniel Green)++ | src/spesh/optimize.c Simplify optimize_getcurhllsym Because `ins->info` is what's used to determine how many operands to access, we don't need to reallocate new operands in the gethllsym case. |
|||
| MoarVM: a5df9ead10 | MasterDuke17++ (committed using GitHub Web editor) | src/spesh/optimize.c Merge pull request #1308 from MasterDuke17/maybe_fix_gethllsym_spesh_optimization |
|||
| nwc10 | brrt: I have not (yet) got one of these: geizhals.eu/raspberry-pi-4-model-b...01761.html | 12:43 | |

| brrt | nwc10: cortex a72... is that an aarch64 chip? | 13:17 | |
| google says it is | |||
| interesting | |||
| nwc10 | yes. and there's a beta of "Rasbperry Pi OS" for 64 bit | 13:27 | |

| brrt | dubitable new achievement in my motoring carreer; I had to jump-start my car | 13:51 | |
| note to anyone trying this, make sure that the cables you use are rated for a decent amount of amperes | |||
| without this it doesn't work as well | 13:52 | ||
| MasterDuke | yeah. i helped a friend jump his car about a year ago. absolutely nothing happened at all with his cables. tried mine, which were a bit more substantial, and it started right up on the first attempt | 13:53 | |
| brrt | hehe... I used the cables from my solar installations... it ultimately did work | 13:55 | |
| MasterDuke | ha | ||
| brrt | with the help of a helpful neighbor | ||
