…pnkfelix Only add codegen backend to dep info if -Zbinary-dep-depinfo is used I am currently migrating the cg_clif build system from using a binary linked to the codegen backend as rustc replacement to passing `-Zcodegen-backend` instead. Without this PR this would force cargo to rebuild the sysroot on any change to the codegen backend even if I explicitly specify that I want it to be preserved, which would make development of cg_clif a lot slower. If you still want to have changes to the codegen backend invalidate the cargo build cache you can explicitly specify `-Zbinary-dep-depinfo`. cc ``@eddyb`` as the codegen backend was initially added to the depinfo for rust-gpu.

Add missing links in platform support docs I was looking at m68k support and saw that https://doc.rust-lang.org/rustc/platform-support.html and the sidebar there were missing some links to target documentation

…i-obk make unaligned_references lint deny-by-default This lint has been warn-by-default for a year now (since rust-lang#82525), so I think it is time to crank it up a bit. Code that triggers the lint causes UB (without `unsafe`) when executed, so we really don't want people to write code like this.

…comment, r=petrochenkov Improve diagnostics for unterminated nested block comment close rust-lang#95283 (This is my first time try to messing around with rust compiler and might get a lot of things wrong... 🙇 )

…ubilee implement SIMD gather/scatter via vector getelementptr Fixes rust-lang/portable-simd#271 However, I don't *really* know what I am doing here... Cc ``@workingjubilee`` ``@calebzulawski`` I didn't do anything for cranelift -- ``@bjorn3`` not sure if it's okay for that backend to temporarily break. I'm happy to cherry-pick a patch that adds cranelift support. :)

…rochenkov Consider lifetimes when comparing types for equality in MIR validator Closes rust-lang#95978 .

…fJung Remove some now-dead code that was only relevant before deaggregation. The code was broken anyway, if the deaggregator is disabled, it would have ICEd on any non-enum Adt r? ```@RalfJung```

…thomcc [test] Add test cases for untested functions for BTreeMap - add `pop_first()`, `pop_last()`, `get_key_value()` and `try_insert()` test cases

…up, r=dtolnay MaybeUninit array cleanup * Links `MaybeUninit::uninit_array` to meta-tracking issue * Links `MaybeUninit::array_assume_init` to meta-tracking issue * Unstably constifies `MaybeUninit::array_assume_init` Another thing worth mentioning: this splits the const feature flag for `maybe_uninit_uninit_array` into `const_maybe_uninit_uninit_array` to avoid weird cases where only one gets stabilised. Note that it may be desired to keep the `array_assume_init` method linked to its dedicated issue, but at least for now, I decided to link to the meta-tracking issue so that all of the methods lead users to the same place. But I can revert that bit if desired. The meta-tracking issue that I filed is rust-lang#96097.

317: Fix use of unaligned references in example r=eldruin a=adamgreig A recent change in Rust to deny unaligned reference by default (rust-lang/rust#95372) caused the upstream rust build of this book to break: rust-lang/rust#96108 (comment) This PR removes the unaligned references, instead using `addr_of!()` to get a raw pointer to print.

This observed 1% regression on ctfe-stress-5.
Much like PR Rollup of 6 pull requests #96015, I do not think I would put individual blame on this rollup PR for the problems we may be seeing over time in ctfe-stress-5.
