| sorear | _14 works fine with the existing nixpkgs code, i tested a while ago | 13:22:12 |

raitobezarius: I've been doing some testing of the above on aarch64-darwin. I found that plain pkgsLLVM.stdenv doesn't build on master, I get a silent failure in compiler-rt. NIX_DEBUG exposes the issue that preConfigure is trying to set CMAKE_LIPO=$(command -v aarch64-apple-darwin-lipo) but this goes straight to the exit/failure handler.
Is pkgsLLVM known (meant?) to work on this platform? Is there a darwin platform it works on?
That's a question for the Darwin folks | 13:28:48 |
| raitobezarius | I have no idea personally | 13:28:52 |
| raitobezarius | I know that rrbutani has been doing work to support better Darwin | 13:29:06 |
| raitobezarius | But it's hard to keep track who is working on what | 13:29:19 |
 p14 | Ah, yeah, apols, I was tagging you in part because I saw your name associated with some Darwin things. | 13:29:36 |
| raitobezarius | I don't do Darwin at all | 13:30:08 |
| raitobezarius | (except the basic stuff to avoid breaking it massively) | 13:31:26 |
| raitobezarius | Overall, I'd say it's fine to aim for a pkgsLLVM that works on Linux first | 13:31:59 |
| p14 | Cool. Is there anything I can do to improve the chances of landing #246577 in the reasonably short term? (In that I have more time to fix things right now than I will in the future) | 13:32:11 |
| p14 | Thinking aloud: I suppose that once it's working it might also be reasonable to bump llvmPackages to llvmPackages_16, so that pkgsLLVM uses the more recent compiler? | 13:33:03 |
| raitobezarius | We are getting into #compilers:nixos.org land but | 13:33:25 |
| raitobezarius | (1) We need to finish the unification work between LLVM14/LLVM15/LLVM16/LLVMgit | 13:33:40 |
| raitobezarius | * (1) We need to finish the unification work between LLVM14/LLVM15/LLVM16/LLVMgit (esp for LLVM17 which I believe is in RC now?) | 13:33:49 |
| p14 | Yep, 17rc is out | 13:33:57 |
| p14 | Interesting to hear that there is a unification effort, that's also good to hear. | 13:34:06 |
| raitobezarius | so any changes that will bring a new discrepancy will probably be delayed because it will introduce more work for that unification stuff | 13:34:09 |
| sorear | iiinteresting | 13:34:28 |
| p14 | Is this effort in a PR or other discussion somewhere? Is there a timeline for it? | 13:35:15 |
| p14 | I may also be interested in helping and testing and whatnot if I get spare bandwidth. | 13:35:42 |
| raitobezarius | (2) I think the timing is complicated, if #246577 is the only change you are hoping to land, I can try to take care of it before going into vacations, but, beyond than that, I think most LLVM maintainers are inactive atm (understandably) | 13:36:22 |
| p14 | I think that's a pretty big step forward in terms of the usability of it. | 13:37:17 |

| raitobezarius | (3) pkgsLLVM is probably low priority and too much to chew for me so at some point, you would have to consider stepping in as a maintainer if you want to see continued stability of that package set | 13:38:14 |
| sorear | would it help if I tested 246577 sooner rather than later? | 13:53:12 |
| p14 | sorear: it would certainly provide more information to me about how well it functions if you want to try and build some other software with it. Feel free to ping me in DMs here (or comment on the PR) as well with any information you glean, though I can't promise to be of much help. | 13:54:08 |
