 emily | I have every package that depends on any of those either dropped, marked broken, or fixed-in-principle locally | 19:25:14 |
| emily | just a lot of testing and fixups to do | 19:25:19 |
 Tristan Ross | Awesome, that GCC stuff will make it easier to move to GCC NG. | 19:25:41 |
| emily | LLVM 18 can probably go away for 26.05 depending on Zig ecosystem and stuff. LLVM 20 is probably imminently droppable if we ship 21 | 19:25:46 |
| emily | 19 might be droppable depending on how much stuff we need to pin after 21 | 19:25:53 |
| Tristan Ross | Zig should be getting 0.15 in a year | 19:26:08 |
| Tristan Ross | At least that's how I see it lol | 19:26:27 |
| emily | Ghostty uses a 0.13 which needs LLVM 18, e.g. | 19:26:34 |
| emily | * Ghostty uses 0.13 which needs LLVM 18, e.g. | 19:26:37 |
| Tristan Ross | Oh, surprised that uses 0.13 | 19:27:02 |
| emily | oh actually it's not because of damned CUDA | 19:27:05 |
| emily | but conceivably we could ship 26.05 with like 2–3 LLVM versions if we're lucky | 19:27:19 |
| emily | that would be nice | 19:27:22 |
| Tristan Ross | I agree and now that I'm back from DEF CON as of Monday night, I can start catching up on things. | 19:27:51 |
| emily | I am still testing LLVM 21 btw | 19:28:16 |
| emily | on Darwin | 19:28:20 |
| emily | it ran into some blockers | 19:28:23 |
| emily | I will get back to it but I diverted for a bit to remove all these compilers | 19:28:30 |
| Tristan Ross | Oh rip, I think there's a merge conflict on it or adjacent PR's. I can clean those up soon. | 19:28:55 |
 rosssmyth | Ok I tried it, and the fact that it is a lie is a lie. My guess is this is a change since the stage 1 stdlib rework. It currently fails while building compiler_builtins. | 19:29:32 |
| rosssmyth | The future is not now | 19:29:48 |
| emily | what I'm gathering is that Rust people love to lie. | 19:31:08 |
| rosssmyth | Perhaps. I think it's closer to there being many moving parts | 19:31:43 |
| emily | (I'm kidding) | 19:32:14 |
| Tristan Ross | I ran into a similar thing trying to get rust to build with LLVM. Some of the solutions I was told ended up being lies. | 19:32:18 |

 Toma | So, anyone want to review https://github.com/NixOS/nixpkgs/pull/387337 ? | 14:54:13 |
| Toma |
(Or do we want to migrate fetchCargoVendor to be less intensive on the cache first?) | 14:54:30 |
| emily | breaking on the non-FOD end, right? | 15:00:22 |
| emily | fixing the cache thing would be nice but I don't immediately see why it'd be a blocker, unless that will require more churn to the things touched here | 15:00:48 |
| Toma | this PR is more important,
but every change in the fetcher is one more unnecessary caching of the deps
(though things are recached every release staging cycle anyways) | 15:04:26 |
