Yes, that is the issue resolved by the pull request that Koakuma mentioned in the changelog: https://github.com/llvm/llvm-project/pull/98713 https://github.com/llvm/llvm-project/commit/6c270a8b9f1e1b80a6016aafb438db7dd89bcb99 which depends on some codegen changes too: https://github.com/llvm/llvm-project/commit/aca971d336d9c7650120fc0fd6dfe58866408216 Those patches missed the LLVM 19 branch point by a couple of weeks: https://github.com/llvm/llvm-project/commit/8f701b5df0adb3a2960d78ca2ad9cf53f39ba2fe They are relatively simple, so maybe we would have a chance of convincing the stable maintainer of LLVM to take them for a later 19.1 release but given how little usage this is likely to see until the full LLVM stack is further developed, I am not sure that petition would be worth it.
