rustc_mir_transform::remove_uninit_drops

Struct RemoveUninitDrops

Source 
pub(crate) struct RemoveUninitDrops;
Expand description

Removes Drop terminators whose target is known to be uninitialized at that point.

This is redundant with drop elaboration, but we need to do it prior to const-checking, and running const-checking after drop elaboration makes it optimization dependent, causing issues like #90770.
