This revision now requires changes to proceed.

It's unclear to me what this is trying to achieve. If it is to prevent

  bb:
    <-- reload inserted here during live range splitting
    $exec = S_OR_B64 $exec, %other
    ... rest of code ...

... then this change only replaces it by:

  bb:
    <-- reload inserted here during live range splitting
    $exec = S_OR_B64_term $exec, %other
    // fallthrough
  
  bb.new:
    ... rest of code ...

The inserted reload code is as incorrect as it was before.
