Expand description
The MIR code often contains variables with type !
that come from panic!
s and similar
!
-returning` functions.
We want to get rid of these variables since they are never initialized. The only instruction
that uses them is StorageLive
/StorageDead
; we remove these, which may hide some UB but
shouldn’t have other consequences.
The now-unused local will then be removed in remove_unused_locals
.
