LLVM update plan? #1048

Open jakirkham opened 1 month ago

Feature request

Currently it looks like llvmlite is pinned to LLVM 14

There was a question in the past about updating to LLVM 15 ( https://github.com/numba/llvmlite/issues/914 ). Though, at the time, the pin had just recently been bumped to LLVM 14

More recently it appears there has been some work done on LLVM 15:

Ofc in the interim LLVM has made a few more releases of its own:

So am curious to hear what the Numba team thinks about updating LLVM. Also interested to know what version(s) is/are being considered for llvmlite pins

Recognize LLVM is a pretty complex library and each update involves a lot of careful testing and thought, which I'm deeply appreciative of

Thanks in advance for your feedback! 🙏

FWIW: llvmlite 0.43 will ship with support for building against 15: https://github.com/numba/llvmlite/pull/1047

Also, there is work being done towards 17: https://github.com/numba/llvmlite/pull/1042#issuecomment-2102466808

To answer the question generally - we update to newer versions of LLVM as fast as we are able, but given resource constraints that's not particularly fast.

In addition to the items in the issue description, other work is needed to move forward beyond 15 (no timelines specified, but it would be nice to complete these prior to the 0.44 release):

Following the successful completion of those items we can then move forward beyond 15.
