Unfortunately, I didn't have much luck debugging the root cause since I don't have access to AVX-512 hardware. I've changed the IR check to a phase before `MacroLogicV` nodes are created, which should hopefully fix the failure.

Even if you don't have access to real hardware, you could try to emulate it with [Intel SDE](https://www.intel.com/content/www/us/en/developer/articles/tool/software-development-emulator.html) to see what's going on. Might be worth a shot. Nevertheless, I will have a look at your patch again in closer detail tomorrow or hopefully on Monday.
