As of [20.1.4](https://github.com/quic/toolchain_for_hexagon/releases/tag/v20.1.4) clang would build this test case within ~20 minutes or so on my Xeon Gold 6136 CPU.
Now, it seems to run for hours - I've let it go for 7 hours and it has not finished. I have seen similar behavior with `llc -O2 matrix-types-spec.ll`.
