Since `std::os::windows::ffi::EncodeWide` was reexported from `std::sys_common::wtf8::EncodeWide`, which has `#![allow(missing_debug_implementations)]` in the parent module, it did not implement `Debug`. When it was moved to `core`, a placeholder impl was added; fill it in.
…tion for reusing it
Replace "use this API instead" with a link to Builder::spawn. Edit the paragraph to make it slightly clearer. The Scope::spawn method already included a. Make the docs for the two nearly the same.

I noticed we had a mix of 0.37 and 0.36 at work, and this was why. As far as I can tell everything still works fine.
When -Z autodiff=Enable is used, the compiler automatically enables fat-lto for all crates. However, proc-macro crates cannot use fat-lto without the -Zdylib-lto flag, causing compilation errors. This commit modifies the lto() method in Session to exclude proc-macro crates from fat-lto when autodiff is enabled, while preserving the existing behavior for all other crate types. The fix ensures that: - Non-proc-macro crates still get fat-lto when autodiff is enabled - Proc-macro crates are excluded from fat-lto when autodiff is enabled - Existing autodiff functionality remains unchanged for regular crates Signed-off-by: Osama Abdelkader <osama.abdelkader@gmail.com>
…hrisDenton Implement `Debug` for `EncodeWide` Since `std::os::windows::ffi::EncodeWide` was reexported from `std::sys_common::wtf8::EncodeWide`, which has `#![allow(missing_debug_implementations)]` in the parent module, it did not implement `Debug`. When it was moved to `core`, a placeholder impl was added; fill it in. This becomes insta-stable. r? libs-api

…-lto, r=petrochenkov Fix autodiff incorrectly applying fat-lto to proc-macro crates Fixes rust-lang#147487
… r=fmease rustdoc: Fix passes order so intra-doc links are collected after stripping passes Fixes regression I introduced in rust-lang#147153. This PR puts back the intra-doc link collecting pass after the stripping items pass, preventing lints to be emitted on non-visible items. Although, might be nice to add a way to change this behaviour. To be discussed later on. cc `@ojeda` r? `@fmease`
