 Marc Jakobi | It's not inline-python either. But I can work around it by disabling library profiling, which probably explains why I wasn't able to reproduce it outside of nix. | 09:48:07 |

| Marc Jakobi | It's a combination of library profiling + template haskell in large modules (500 LOC). Please don't ask me why we have modules with ~500 LOC 🙈 | 13:39:15 |
 magic_rb | 500 loc is not that much? Id think | 13:39:53 |
| magic_rb | If you said 5000loc then sure | 13:40:00 |
| Marc Jakobi | I don't know how much the TH is adding to those lines | 13:44:38 |
| magic_rb | Ah right, lots of TH | 13:44:56 |
 Teo (he/him) | You can use https://downloads.haskell.org/ghc/latest/docs/users_guide/debugging.html#ghc-flag-ddump-splices if you want to see the stuff TH outputs | 14:07:00 |
 sterni (he/him) | you should also probably try to figure out whether GHC or the linker is the problem | 14:44:05 |

| sterni (he/him) | teo (they/he): is there an issue alreday for the issue that finalStage = Stage2 is silently ignored? | 10:06:06 |
| Teo (he/him) | Not as far as I know. it would be good to make one | 10:07:18 |
| Teo (he/him) | even if there is one, it would put it back on folks' radar | 10:07:32 |
| sterni (he/him) | https://gitlab.haskell.org/ghc/ghc/-/issues/26289 | 10:45:58 |
| sterni (he/him) | let's try this again https://discourse.nixos.org/t/call-for-contributions-we-are-updating-to-ghc-9-10-2/67756 (lmk about any typos) | 11:36:01 |
| sterni (he/him) | funny that we did 9.2, 9.4, 9.6 and 9.8 without ever posting on discourse | 11:36:26 |
| sterni (he/him) | though 8.10 -> 9.0 truly was the big one | 11:36:36 |
| sterni (he/him) | I'm a bit concerned people will be scared away by this wall of text, but I'm the wrong person to write a short post. Also documentation on contributing to haskellPackages is really spotty. | 11:38:41 |
| sterni (he/him) | The short intro I wrote (and copied here) for 9.0.2 post is kinda good, maybe we should just put that in the Nixpkgs manual as a starting point. | 11:39:11 |
 chreekat | It's an excellent post | 11:59:28 |

 emily | has anyone noticed a GHC build hanging around building ghc-9.8.4 (buildPhase): | Run Ghc CompileCWithGhc Stage1: rts/Hash.c => _build/stage1/rts/build/c/Hash.thr_debug_dyn_o with a bunch of C compilers using all the CPU they can find overnight but seemingly not progressing | 14:11:44 |
| emily | (I suspect the answer is no and this is an LLVM 21 regression but I thought I'd check) | 14:11:53 |
 maralorn | sterni: Excellent post. I found two typos in the paragraph
When you’ve found a fix for a package, make sure to add a comment next to your override explaining explaining why it is needed and ideally link an issue or PR that needs to be resolved upstream for us to drop the override (if no issue exist, do open one).
Their is a double "explaining" and "no issue exist" is missing numerus congruency.

| sterni (he/him) | emily: nope and I have compiled a quite a few GHCs on haskell-updates the last week | 17:07:09 |
| sterni (he/him) | though x86_64-linux so no LLVM involvement at all | 17:07:37 |
