…ons. For those consts and functions, only the summary is kept and a reference to the `char` associated const/method is included. Additionaly, re-exported functions have been converted to function definitions that call the previously re-exported function. This makes it easier to add a deprecated attribute to these functions in the future.
This commit suggests replacing typeof(...) with an actual type of "...",
for example in case of `typeof(1)` we suggest replacing it with `i32`.
If the expression
- Is not const (`{ let a = 1; let _: typeof(a); }`)
- Can't be found (`let _: typeof(this_variable_does_not_exist)`)
- Or has non-suggestable type (closure, generator, error, etc)
we don't suggest anything.
Implement sym operands for global_asm! Tracking issue: rust-lang#93333 This PR is pretty much a complete rewrite of `sym` operand support for inline assembly so that the same implementation can be shared by `asm!` and `global_asm!`. The main changes are: - At the AST level, `sym` is represented as a special `InlineAsmSym` AST node containing a path instead of an `Expr`. - At the HIR level, `sym` is split into `SymStatic` and `SymFn` depending on whether the path resolves to a static during AST lowering (defaults to `SynFn` if `get_early_res` fails). - `SymFn` is just an `AnonConst`. It runs through typeck and we just collect the resulting type at the end. An error is emitted if the type is not a `FnDef`. - `SymStatic` directly holds a path and the `DefId` of the `static` that it is pointing to. - The representation at the MIR level is mostly unchanged. There is a minor change to THIR where `SymFn` is a constant instead of an expression. - At the codegen level we need to apply the target's symbol mangling to the result of `tcx.symbol_name()` depending on the target. This is done by calling the LLVM name mangler, which handles all of the details. - On Mach-O, all symbols have a leading underscore. - On x86 Windows, different mangling is used for cdecl, stdcall, fastcall and vectorcall. - No mangling is needed on other platforms. r? `@nagisa` cc `@eddyb`

Suggest replacing `typeof(...)` with an actual type
This PR adds suggestion to replace `typeof(...)` with an actual type of `...`, for example in case of `typeof(1)` we suggest replacing it with `i32`.
If the expression
1. Is not const (`{ let a = 1; let _: typeof(a); }`)
2. Can't be found (`let _: typeof(this_variable_does_not_exist)`)
3. Or has non-suggestable type (closure, generator, error, etc)
we don't suggest anything.
The 1 one is sad, but it's not clear how to support non-consts expressions for `typeof`.

…lacrum Check for git submodules in non-git source tree. People occasionally download the source from https://github.com/rust-lang/rust/releases, but those source distributions will not work because they are missing the submodules. They will get a confusing `failed to load manifest for workspace member` error. Unfortunately AFAIK there is no way to disable the GitHub source links. This change tries to detect this scenario and provide an error message that guides them toward a solution. Closes rust-lang#95608

Allow multiple derefs to be splitted in deref_separator Previously in rust-lang#95649 only a single deref within projection was supported and multiple derefs caused a bunch of issues, this PR fixes those issues. ``@oli-obk`` helped a ton again ❤️
