Oh, I see!

Yes I guess, I created already a PR: https://github.com/numba/llvmlite/pull/684

The other problem I have is that I still need a confirmation that the patch is valid (I validated with llvm and numba testsuites on PowerPC HW, but have no confirmation from an insider or a public testsuite).
