alexcrichton opened PR #5889 from remove-widening-instruction to main:

This was added for the wasm SIMD proposal but I've been poking around at this recently and the instruction can instead be represented by its component parts with the same semantics I believe. This commit removes the instruction and instead represents it with the existing iadd_pairwise instruction (among others) and updates backends to with new pattern matches to have the same codegen as before.

This interestingly entirely removed the codegen rule with no replacement on the AArch64 backend as the existing rules all existed to produce the same codegen.
