| Geth | MoarVM: nwc10++ created pull request #1671: Remove temporary define for migrating Rakudo extops |

| Nicholas | ##[error]No hosted parallelism has been purchased or granted. To request a free parallelism grant, please fill out the following form aka.ms/azpipelines-parallelism-request | 10:09 | |
| er right. I *think* that someone within "our" "Azure DevOps Organization" likely needs to do this. | 10:11 | ||
| but right now, we seem to be stuck in a fog of default-fail | |||

| lizmat | good *, #moarvm | 11:33 | |
| so I started working on really using uint in the core for all of those pesky cases where we need to check for < 0 | |||
| so I reduced the AT-POS for native arrays taking a uint as index | |||
| multi method AT-POS(intarray:D: uint $idx --> int) is raw { | 11:34 | ||
| nqp::atposref_i(self,$idx) | |||
| } | |||
| this is still slower than the Int:D variant, because it doesn't get inlined | |||
| AT-POS BB(7284, 76 bytes) -> BB(1): | |||
| target has a :noinline instruction - ins: param_rp_o | |||
| what am I missing? | |||
| Nicholas | (Hi. I don't know enough to even start to answer this) | 11:35 | |
| lizmat neither... but I hope MasterDuke or nine will be able to have an idea | 11:36 | ||
| nine | lizmat: logs.liz.nl/moarvm/2022-02-06.html#16:49 | 11:57 | |
| lizmat | aaah... ok, I thought that had already made it into the release | 11:58 | |
| nine: btw, it's irclogs.raku.org nowadays :-) | |||
| ok /me needs to be a little more patient then | |||

| lizmat | m: multi a(uint) { dd }; multi a(Int:D) { dd }; a 10 # nine, would your work have it dispatch to the uint candidate ? | 13:23 | |
| camelia | sub a(Int:D) | ||
| lizmat | OOC | ||
| jnthnwrthngtn | I think the only way a literal ends up getting passed as a native is if there's another argument that is a native and it's a multi-sub dispatch so the optimizer can do the transform | 13:52 | |
| Nicholas | lizmat: "but I hope MasterDuke or nine" - you got jnthnwrthngtn - hopefully second best will do :-) | 14:21 | |

| nine | Right now the optimiyer isn't smart enough to pass a native for a literal, even in multi dispatch. That's exactly the optimization opportunity I'm in the process of investigating | 16:30 | |

| lizmat | nine: would this be the way to make $_ a uint on simple loops? | 19:59 | |
