The subject of Tapir came up in this thread a little while ago. Put simply, Tapir added 3 new instructions to LLVM's IR to make it possible to express parallelism in code such that the various optimizers in the middle/back end could do intelligent things, and it looks like they got pretty good performance improvements by doing so. Would it be worth considering adding these instructions to Cranelift's IR?

Cool paper and cool IR but out of scope for Cranelift.
