Hi llvm 19 has been released. Can we start using it in head? My smoke test of it with 9.10.1 was fine. Thanks George

What do you mean by using it in head? Expand the current range of acceptable LLVM versions? My hunch would be that such a PR could be merged quite easily. Maybe next week though due to the current imminent release cut? Or do you expect this to be in 9.12 as well? Best, Moritz On Wed, 25 Sept 2024 at 22:08, George Colpitts wrote:

I think #25295 https://gitlab.haskell.org/ghc/ghc/-/issues/25295 which Matthew just opened will be fine. It would be nice to have in 12.1 but I assume it's a bit too late, particularly if it just works as I expect than it isn't that important to be officially supported. Moritz, Matthew thanks for your quick response. Cheers, George My hunch would be that such a PR could be merged quite easily. Maybe next

Best, Moritz

FWIW, GHC-9.10.1 docs [1] say

Note that this GHC release expects an LLVM version in the 13 up to 16 (not inclusive) release series.

which is far behind 19... [1] https://downloads.haskell.org/ghc/9.10.1/docs/users_guide/codegens.html#llvm... - Oleg On 25.9.2024 18.22, George Colpitts wrote:

The upper bound is bumped to 18 already on master. On Wed, Sep 25, 2024 at 4:28 PM Oleg Grenrus wrote:
