-// Various tests around the behavior of zero-sized arrays and
-// enum niches, especially that they have coherent size and alignment.
-
-// The original problem in #99836 came from ndarray's `TryFrom` for
-// `SliceInfo<[SliceInfoElem; 0], Din, Dout>`, where that returns
-// `Result<Self, ShapeError>` ~= `Result<AlignedZST, TypeWithNiche>`.
-// This is a close enough approximation:
-#[rustc_layout(debug)]
-type AlignedResult = Result<[u32; 0], bool>; //~ ERROR: layout_of
-// The bug gave that size 1 with align 4, but the size should also be 4.
-// It was also using the bool niche for the enum tag, which is fine, but
-// after the fix, layout decides to use a direct tagged repr instead.
-
-// Here's another case with multiple ZST alignments, where we should
-// get the maximal alignment and matching size.
-#[rustc_layout(debug)]
-enum MultipleAlignments { //~ ERROR: layout_of
-    Align2([u16; 0]),
-    Align4([u32; 0]),
-    Niche(bool),
-}
-
-// Tagged repr is clever enough to grow tags to fill any padding, e.g.:
-// 1.   `T_FF` (one byte of Tag, one byte of padding, two bytes of align=2 Field)
-//   -> `TTFF` (Tag has expanded to two bytes, i.e. like `#[repr(u16)]`)
-// 2.    `TFF` (one byte of Tag, two bytes of align=1 Field)
-//   -> Tag has no room to expand!
-//   (this outcome can be forced onto 1. by wrapping Field in `Packed<...>`)
