emily | if following the incremental plan, everything would initially default to the value it currently has based on useLLVM etc. (and assert if anyone tries to specify something mismatching), and then in the final step they would become mandatory to set if not using the useLLVM back-compatibility shim | 02:21:01 |
emily | (though presumably null is fine for freestanding platforms that don't care) | 02:21:08 |
Tristan Ross | Oh | 02:21:41 |
emily | (defaulting based on platform is probably fine too although ideally we wouldn't assume that x86_64-linux means GCC etc. in the long run) | 02:25:42 |
Tristan Ross | If I want multiple lib.warnIf with the oldest supported release thing, I could use lib.pipe so I don't have to put things in parentheses? | 02:31:13 |
emily | I use assert …; for that stuff. but I think you'd want to get things wired up before actually expecting people to set it per ^, otherwise it'll be one very big PR | 02:32:39 |
Tristan Ross | Oh | 02:32:52 |
Tristan Ross | It wouldn't even take effect until 25.11 | 02:33:36 |
emily | well, ideally we can get the prep done before the 25.05 release :) | 02:36:59 |
emily | splitting it up will probably help with that | 02:37:11 |
Tristan Ross | Yeah | 02:37:22 |
Tristan Ross | Ok, the "legacy" use* has been wired up to set the new attributes and pkgsLLVM looks to work with that | 02:37:50 |
Tristan Ross | Oh I've got good news | 03:08:03 |
Tristan Ross | emily: the seccomp issue is not an issue anymore lol, checks work now | 03:08:21 |
Tristan Ross | I didn't change anything lol | 03:08:33 |
Tristan Ross | Upstream must've fixed it | 03:08:42 |
Tristan Ross | Or it might've been a codegen bug? | 03:09:00 |
emily | that's one fewer problem at least :) | 03:13:57 |
Tristan Ross | Yeah lol | 03:14:32 |
Tristan Ross | Cool pkgs/development/compilers/llvm/common/default.nix no longer depends on useLLVM | 03:18:40 |
Tristan Ross | Just need to figure out why threadsCross has an optional for !useLLVM | 03:27:48 |
Tristan Ross | And then we've got the rust mess | 03:27:54 |
Tristan Ross | I've been able to adjust some other stuff thankfully because of bugs which no longer occur | 03:28:36 |
Tristan Ross | I bisected the change to John Ericson (https://github.com/NixOS/nixpkgs/pull/73195/files#diff-ab5748dc9567516fefba8344056b51ec1866adeace380f46e58a7af3d619ea22R11302) | 03:31:14 |
emily | I think that is just inherited from crossLibcStdenv, maybe. | 03:37:05 |
emily | I think mcfgthreads might be kind of broken though. there's some weird GCC patch stuff that I think no longer applies(?) | 03:37:28 |
Tristan Ross | So I can just drop that case of useLLVM? | 03:41:18 |
emily | I don't know. I just mean it looks like Ericson was copying it from crossLibcStdenv which already had the conditional. | 03:41:44 |
Tristan Ross | Oh | 03:42:23 |
Tristan Ross | I'll remove it and we'll see what Ericson thinks | 03:43:19 |
