Struct rustc_mir_transform::remove_uninit_drops::RemoveUninitDrops

pub struct RemoveUninitDrops;

Removes Drop and DropAndReplace 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.

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
