<pre>I've encountered this bug in the latest LLVM release 11.0.0. The link to
upstream issue: <a href="https://github.com/ziglang/zig/issues/6812">https://github.com/ziglang/zig/issues/6812</a>. I haven't had the
time to create the minimal reduction yet, but will do my best to come up with
something ASAP. I'll also test it against the LLVM upstream, and see if the
issue has already been fixed. Having said that, if anyone knows of any fix, I'd
really appreciate any links to some diffs. Finally, I'll be happy to work on a
fix for this if it's not fixed yet.
