Hi @fhahn, I need to kindly ask you a question. A fix for the issue #126836 has been aimed for LLVM20. Do you have any plans to implement it for the LLVM20 release branch too? It seems the PRs that fix this issue depend too much on the current state of the main branch to make them cherry-pick as-is.
