alexcrichton opened PR #8167 from alexcrichton:vec-load-lane-from-memory to bytecodealliance:main:

Going through old PRs I stumbled across #2716 which is quite old at this point. Upon adding the tests to main I see that most of it is actually implemented except for load-lane-from-memory where the lane size is 8 or 16 bits. That requires explicitly opting-in with sinkable_load_exact so this PR now subsumes the tests of #2716 in addition to implementing this missing hole in lowerings.

This refactoring shuffles around where definitions are located to more easily have access to Value to perform the relevant match. The generic vec_insert_lane helper is now gone as well in lieu of direct matches on insertlane lowerings.

Closes #2716
