 emily | 12, 13, 14, 16, 18 should be pretty easy drops at this point. maybe 17 too | 01:55:35 |
| emily | plausible that 25.11 will ship with 15, 17, 19, 20 | 01:55:44 |

Especially, old GHC versions are some of the primary consumers of old LLVM versions in nixpkgs which also puts strain on more than the Haskell maintainers.
| 01:56:28 |
| emily | yes, I know | 01:57:21 |
| emily | I've put maybe 5 hours of my life into arguing about ancient GHCs using ancient LLVMs :P | 01:57:38 |
| emily | glad there is finally some movement on it | 01:57:43 |
| emily | AIUI the next Stackage LTS will be 9.10, so if 25.11 shipped with that then we'd still have 9.6, 9.8, 9.10, 9.12, all but the latter of which use LLVM 15 | 01:59:12 |
| emily | it will only help dropping LLVM 12 | 02:00:15 |
| hexa | automatic bugs against packages would be something | 02:00:47 |
| emily | possible that the version constrains can be loosened or that LLVM support could be dropped from old versions (it is only necessary for weird platforms generally, aarch64-darwin was LLVM only in old releases but I think there is a native backend, I don't know what version added that though) | 02:00:55 |
| emily | but there was pushback against those suggestions when I brought them up | 02:01:07 |
| hexa | (well not in the current form of github issues, but) | 02:01:30 |
| emily | so I would wager LLVM 15 probably continues its zombie life | 02:01:17 |
