It was added in #129523 to enable building on stable when there were
`cfg(bootstrap)` occurrences in the crate. But those are gone now, so
the section can be removed.
Use `std::mem::{size_of, size_of_val, align_of, align_of_val}` from the
prelude instead of importing or qualifying them.
These functions were added to all preludes in Rust 1.80.

The `max_line_length` property was set to 100 for all filetypes, which
led to git commit messages being wrapped at 100 characters instead of
the usual 75. This introduces an exception for the special file used by
git to write commit messages.

A new syntax node `ast::VariantDef` has been introduced to map between the HIR node and the AST.
The files have been updated with `cargo test -p xtask`.

Clean up various LLVM FFI things in codegen_llvm
cc ```@ZuseZ4``` I touched some autodiff parts
The major change of this PR is [bfd88ce](https://github.com/rust-lang/rust/pull/137549/commits/bfd88cead0dd79717f123ad7e9a26ecad88653cb) which makes `CodegenCx` generic just like `GenericBuilder`
The other commits mostly took advantage of the new feature of making extern functions safe, but also just used some wrappers that were already there and shrunk unsafe blocks.

Change the way that underline positions are calculated by delaying using
the "visual" column position until the last possible moment, instead
using the "file"/byte position in the file, and then calculating visual
positioning as late as possible. This should make the underlines more
resilient to non-1-width unicode chars.
Unfortunately, as part of this change (which fixes some visual bugs)
comes with the loss of some eager tab codepoint handling, but the output
remains legible despite some minor regression on the "margin trimming"
logic.
When encountering a single line span that is wider than the terminal, we keep context at the start and end of the span but otherwise remove the code from the middle. This is somewhat independent from whether the left and right margins of the output have been trimmed as well.

Address part of #137680 (missing handling of the long suggestion). Fix#125581.
`-Zteach` is perma-unstable, barely used, the highlighting logic buggy and the flag being passed around is tech-debt. We should likely remove `-Zteach` in its entirely.
use target compiler on llvm-bitcode-linker
The build compiler is already resolved inside the `ToolBuild` step, so we should pass only the target compilers for `Mode::ToolRustc` tools.

Currently it relies on special treatment of `kw::Empty`, which is really
easy to get wrong. This commit makes the special case clearer in the
type system by using `Option`. It's a bit clumsy, but the synthetic name
handling itself is a bit clumsy; better to make it explicit than sneak
it in.
Fixes#133426.
Use `default_field_values` for `rustc_errors::Context`, `rustc_session::config::NextSolverConfig` and `rustc_session::config::ErrorOutputType`
Wanted to see where `#![feature(default_field_values)]` could be used in the codebase. These three seemed like no-brainers. There are a bunch of more places where we could remove manual `Default` impls, but they `derive` other traits that rely on `syn`, which [doesn't yet support `default_field_values`](https://github.com/dtolnay/syn/issues/1774).
Break critical edges in inline asm before code generation
An inline asm terminator defines outputs along its target edges -- a
fallthrough target and labeled targets. Code generation implements this
by inserting code directly into the target blocks. This approach works
only if the target blocks don't have other predecessors.
Establish required invariant by extending existing code that breaks
critical edges before code generation.
Fixes#137867.

Revert #138019 after further discussion about how hir-pretty printing should work
After some more discussion, #138019 was probably merged a little fast. Though there probably is a real bug in pretty printing, it is not feasible to add similar pretty printing routines for all attributes, and making this specific exception is likely not desired either. For more context, see post-merge comments on #138019
I kept the tests around, but reverted the hir-pretty change.
