`-Z patchable-function-entry` works like `-fpatchable-function-entry` on clang/gcc. The arguments are total nop count and function offset. See MCP rust-lang/compiler-team#704

See [RFC](https://github.com/maurer/rust-rfcs/blob/patchable-function-entry/text/0000-patchable-function-entry.md) (yet to be numbered) TODO before submission: * Needs an RFC * Improve error reporting for malformed attributes

Removes an `unsafe` in favor of just using `String` methods.

Co-authored-by: Ralf Jung <post@ralfj.de>

Currently bootstrap doesn't use any inner paths from rust-analyzer and bootstrap with `ShouldRun::create_or_deps`. Signed-off-by: onur-ozkan <work@onurozkan.dev>

…s-pr, r=estebank,workingjubilee patchable-function-entry: Add unstable compiler flag and attribute Tracking issue: rust-lang#123115 Add the -Z patchable-function-entry compiler flag and the #[patchable_function_entry(prefix_nops = m, entry_nops = n)] attribute. Rebased and adjusted the canditate implementation to match changes in the RFC.

…e, r=Kobzol make cargo submodule optional Right now, we fetch the cargo submodule no matter what, even if the command we are running doesn't need it (e.g., `x build compiler library`). This PR changes that to only fetch the cargo submodule when it's necessary. For more context, see the zulip thread: https://rust-lang.zulipchat.com/#narrow/stream/326414-t-infra.2Fbootstrap/topic/Why.20is.20cargo.20always.20checked.20out.3F

core: avoid `extern type`s in formatting infrastructure ```@RalfJung``` [said](https://rust-lang.zulipchat.com/#narrow/stream/219381-t-libs/topic/Use.20of.20.60extern.20type.60.20in.20formatting.20machinery/near/446552837): >How attached are y'all to using `extern type` in the formatting machinery? Seems like this was introduced a [long time ago](rust-lang@34ef8f5). However, it's also [not really compatible with Stacked Borrows](rust-lang/unsafe-code-guidelines#256), and only works currently because we effectively treat references-to-extern-type almost like raw pointers in Stacked Borrows -- which of course is unsound, it's not how LLVM works. I was planning to make Miri emit a warning when this happens to avoid cases like [this](rust-lang#126814 (comment)) where people use extern type specifically to silence Miri without realizing what happens. but with the formatting machinery using extern type, this warning would just show up everywhere... > > The "proper" way to do this in Stacked Borrows is to use raw pointers (or `NonNull`). This PR does just that. r? ```@RalfJung```

… r=cuviper Simplify `str::clone_into` Removes an `unsafe` in favor of just using `String` methods.

Support fetching `Attribute` of items. Fixes [https://github.com/rust-lang/project-stable-mir/issues/83](https://github.com/rust-lang/project-stable-mir/issues/83) `rustc_ast::ast::Attribute` doesn't impl `Hash` and `Eq`. Thus it cannot be directly used as key of `IndexMap` in `rustc_smir::rustc_smir::Tables` and we cannot define stable `Attribute` as index to `rustc_ast::ast::Attribute` like `Span` and many other stable definitions. Since an string (or tokens) and its span contain all info about an attribute, I defined a simple `Attribute` struct on stable side. I choose to fetch attributes via `tcx::get_attrs_by_path()` due to `get_attrs()` is marked as deprecated and `get_attrs_by_name()` cannot handle name of multiple segments like `rustfmt::skip`. r? `@celinval`

…s, r=oli-obk Tighten `fn_decl_span` for async blocks Tightens the span of `async {}` blocks in diagnostics, and subsequently async closures and async fns, by actually setting the `fn_decl_span` correctly. This is kinda a follow-up on rust-lang#125078, but it fixes the problem in a more general way. I think the diagnostics are significantly improved, since we no longer have a bunch of overlapping spans. I'll point out one caveat where I think the diagnostic may get a bit more confusing, but where I don't think it matters. r? ````@estebank```` or ````@oli-obk```` or someone else on wg-diag or compiler i dont really care lol
