| hexa | removed here in 16.0.0-rc1 | 01:31:43 |
 emily | "Now that all jobs have moved over to the new style of Lit configuration, we can remove all traces of the legacy testing configuration system." is not promising for backportability | 01:37:05 |
| emily | maybe patching the shebang on lit will help? | 01:37:35 |
| emily | or could just disable tests for those old versions. or let them break and see how much people really care about old LLVMs. | 01:37:49 |
| hexa | the first estimate is ~115 packages in the python scope per platform | 01:41:03 |
| emily | it looks like it's only for libcxx and libunwind | 01:40:43 |

| emily | I think we can disable tests on old versions of those. | 01:40:43 |
| hexa | this could be all that's needed | 01:42:57 |
| hexa | do I start contributing to llvm now? 😫 | 01:43:36 |
| hexa | also tblgen iirc, but i'd have to check | 01:44:14 |
| emily | they don't maintain the old versions at all | 01:43:49 |
| hexa | hm no | 01:45:31 |
| emily | everything but 20 is technically EOL | 01:43:57 |
| hexa | ah, great | 01:47:13 |
| emily | which is also why as many of them as possible should go away in 25.11 | 01:44:12 |
| emily | so some of those Python packages may be casualties anyway | 01:44:22 |
| hexa | https://github.com/numba/llvmlite | 01:48:09 |
| hexa | I'm frankly not sure why they lag behind that much | 01:48:24 |
| emily | LLVM does a fair amount of breaking changes I think. | 01:50:39 |
| emily | you're meant to upstream things | 01:51:13 |
| emily | fwiw they apparently have experimental LLVM 16 support | 01:52:53 |
| emily | from the Fedora package:
# For 0.44.0, LLVM 15 is the default. LLVM 16 support is “experimental;” we can
# try it if we need to.
| 01:53:00 |
| hexa | ok, neat | 01:54:33 |
| emily | however a bunch of GHCs keep 15 around anyway so that version is probably relatively safe. | 01:53:43 |
| hexa | the haskell wants to cull some of these | 01:55:23 |
| emily | 12, 13, 14, 16, 18 should be pretty easy drops at this point. maybe 17 too | 01:55:35 |
