Hint that memchr returns an in-bounds index #159784 (Hint that memchr returns an in-bounds index)
Add regression test for #132767 #160027 (Add regression test for [ICE]: maybe try to call try_normalize_erasing_regions instead #132767)
Update browser-ui-test version to 0.25.0 #160030 (Update browser-ui-test version to 0.25.0)
Improve consistency of attribute error messages (part 2) #160046 (Improve consistency of attribute error messages (part 2))
Fix associated function suggestion for generic ADTs #160056 (Fix associated function suggestion for generic ADTs)

Coercing the fn item `bar` to a fn pointer while `Foo::value` holds the associated-type projection `<<T as Func>::Ret as Id>::Assoc` used to ICE during normalization ("maybe try to call `try_normalize_erasing_regions` instead"). It now reports the ordinary `u32: Id` trait-bound error instead of crashing.

The carets should ideally point to the path, not the entire attribute, but that's hard to achieve with the current code structure.

The carets already point to just the attribute path, which is what we want.

…result-bounds, r=Darksonn Hint that memchr returns an in-bounds index `memchr_aligned` always returns an index within the input slice, but that fact was not visible to callers after inlining. Record the invariant with `assert_unchecked` so LLVM can simplify callers such as `str::find(char)` In x86_64 codegen, `find(char)` shrank from 463 to 377 bytes.

Add regression test for rust-lang#132767 Closes rust-lang#132767. Coercing a fn item to a fn pointer with an associated type projection used to ICE during normalization. now errors with E0277.

…est, r=GuillaumeGomez Update `browser-ui-test` version to `0.25.0` With this new version we should be able to finally add a regression test for [the "code copy" ](rust-lang#158137). r? ghost
