| leont | I was looking at making improving the atomics, and frankly getting rid of libatomic_ops would make everything easier. | 15:41 | |
| [Coke] | :) | ||
| leont | C11 is lightyears ahead, and since 2022 MSVC also supports them so I think that'd be fine | ||

| japhb | What makes the C11 atomics so much better than libatomic_ops? | 20:26 | |
| Geth | MoarVM: Leont++ created pull request #1943: Remove libatomic_ops |
20:59 | |
| MoarVM: Leont++ created pull request #1944: Stop using Windows 2019 runner |
21:19 | ||
| leont | It would be helpful to merge the second one before the 10th, because of the brown-outs | 21:20 | |
| japhb | leont: Will do as soon as we get CI on it. | 21:22 | |
| My question above still stands. :-) | |||
| (Don't get me wrong, I'm all for using standards when available. You just made it sound like it would be a massive improvement, and not just in reducing stuff we have to support.) | 21:23 | ||
| leont | Several things really. | 21:25 | |
| japhb | (I guess I should say "standards *that don't suck*", because of course some of them do. We're going to assume the C11 committee did better than that. ;-) ) | ||
| leont | Firstly, it supports explicit memory ordering, which means we can choose the most performant option that is appropriate for the specific case. | 21:27 | |
| One of the other nice things is that C11 atomics are type generic. So we don't need to cast from and to AO_t* all the time. This makes it much easier to use it with pointers in particular. | |||
| Secondly, it supports more options. It seems libatomics lacks a plain exchange (or maybe I fail to find it), which is sometimes needed. | 21:28 | ||
| japhb | Fair enough. Thanks for the summary! | 21:30 | |
| dev.azure.com/MoarVM/MoarVM/_build...amp;l=1450 <-- Mac failure with this PR in place? | 21:43 | ||
| leont | That is also failing on main | 21:44 | |
| japhb | dev.azure.com/MoarVM/MoarVM/_build...6357f73cc3 <-- Ubuntu 20.04 retired | ||
| dev.azure.com/MoarVM/MoarVM/_build...67f910b2b1 <-- same | 21:45 | ||
| OK, so it looks like some CI cleanup is needed. But I'll merge #1944 now. | |||
| leont | Yeah I was looking at the Ubuntu issue, but I have no idea what to do about Mac | 21:46 | |
| japhb | Wait ... how do the clang/gcc _no_c11_atomics builds pass now that there is now libAO? | ||

| japhb | Oh duh, because 1943 hasn't been merged. I'm apparently an idiot. | 21:50 | |
| Geth | MoarVM/main: 58eda115fd | (Leon Timmermans)++ | 2 files Stop using Windows 2019 runner They are no longer supported starting 2025-06-30. See also github.com/actions/runner-images/issues/12045 |
21:51 | |
| MoarVM/main: 0c63932cf2 | (Geoffrey Broadwell)++ (committed using GitHub Web editor) | 2 files Merge pull request #1944 from Leont/windows-2022 Stop using Windows 2019 runner Notes: * There were two CI runs canceled because the Ubuntu 20.04 they specify is no longer supported in Azure. This will need a PR of its own for cleanup. * There is a Mac CI failing that is also failing on main (so no difference from this PR). |
|||
| leont | I don't understand the Mac failure at all | 22:00 | |
| Geth | MoarVM: Leont++ created pull request #1945: Upgrade to Ubuntu 24.04 |
22:08 | |
| MoarVM/main: 78acd73d00 | timo++ (committed using GitHub Web editor) | 3 files Less memory waste binslurp and normalizecodes (#1938) * In read_fhb aka nqp::readfh don't keep too-large buffers around. We were allocating as much space as the caller was asking for, but in rakudo for slurp we are passing 1 megabytes as the size by default. ... (7 more lines) |
