It is now exactly equivalent to lookup_char_pos.
This commit adds a test demonstrating the current behaviour when a macro defined in a module with the `#[macro_export]` is imported from the module rather than the crate root.
Implicit promotion on the other hand has very strict rules on what may be done
- Make links relative. - Adjust links from old 2018-edition book. - Fix broken link in `let` docs.
This commit implements the `{read,write}_vectored` methods on more types
in the standard library, namely:
* `std::fs::File`
* `std::process::ChildStd{in,out,err}`
* `std::io::Std{in,out,err}`
* `std::io::Std{in,out,err}Lock`
* `std::io::Std{in,out,err}Raw`
Where supported the OS implementations hook up to native support,
otherwise it falls back to the already-defaulted implementation.…-mut, r=pnkfelix Mark variables captured by reference as mutable correctly Closesrust-lang#59620 r? @pnkfelix

…k, r=ehuss Copy book.toml unstable book generator Solves rust-lang#59554 and adds a book title to the unstable book. I assume that [copy_recursive](https://github.com/rust-lang/rust/blob/acd8dd6a50d505057a7d7ad8d0d7a4c2bd274200/src/tools/unstable-book-gen/src/main.rs#L105) will take files regardless of their type (`.md` or `.toml`). Although I had a hard time time testing it. A second pair of eyes is definitely needed.
Retire `IsNotConst` naming This naming scheme caused a lot of confusion lately (including ICEs) due to misrefactored code. Also clean up the initialization code for said flag. r? @eddyb previous discussions: rust-lang#58784 (comment)rust-lang#58403 (comment)

Use SecRandomCopyBytes instead of /dev/urandom on MacOS SecRandomCopyBytes is [available since MacOS 10.7](https://developer.apple.com/documentation/security/1399291-secrandomcopybytes?language=objc) which is the minimum supported version and which was suggested in rust-lang#58901 (comment) is the earliest version currently in use. This matches the behaviour of other platforms which have a random number generator syscall available.
…ize, r=pnkfelix In `-Zprint-type-size` output, sort enum variants by size. It's useful to see the biggest variants first. r? @pnkfelix

…x, r=Centril Fix paste error in split_ascii_whitespace docs. It was accidentally still testing the unicode version, `split_whitespace`.
…Gomez Exclude some copies of old book editions from search engines These are only stubs that confuse search engine users. There's no useful content in these locations.
Use a proc macro to declare preallocated symbols r? @petrochenkov
… r=alexcrichton compiletest normalization: preserve non-JSON lines such as ICEs Currently, every non-JSON line from stderr gets normalized away when compiletest normalizes the output. In particular, ICEs get normalized to the empty output. That does not seem desirable, so this changes normalization to preserve non-JSON lines instead. Also see Manishearth/compiletest-rs#169: because of that bug, Miri currently *looks* green in the toolstate, but some tests ICE. That same bug is likely no longer present in latest compiletest because the error code gets checked separately, but it still seems like a good idea to also make sure that ICEs are considered stderr output: This change found an accidental user-visible `error!` in CTFE validation (fixed), and a non-deterministic panic when there are two `main` symbols (not fixed, no idea where this comes from). Both got missed before because non-JSON output got ignored.

…mp, r=alexcrichton Exclude profiler-generated symbols from MSVC __imp_-symbol workaround. LLVM's profiling instrumentation adds a few symbols that are used by the profiler runtime. Since these show up as globals in the LLVM IR, the compiler generates `dllimport`-related `__imp_` stubs for them. This can lead to linker errors because the instrumentation symbols have weak linkage or are in a comdat section, but the `__imp_` stubs aren't. Instead of trying to replicate the linkage/comdat setup for the stubs, this PR just excludes the profiler-related symbols from stub-generation since they aren't supposed to be referenced via `__declspec(dllimport)` anywhere anyway. r? @alexcrichton EDIT: I considered making this more general, i.e. inferring from the symbol name if it is a Rust symbol or not. But then I figured out that that would yield false negatives for `#[no_mangle]` et al, so I went with a blacklist approach.
update polonius-engine This updates polonius-engine to [version 0.7.0](https://github.com/rust-lang/polonius/blob/master/RELEASES.md#v070), which adds a hybrid algorithm that starts off with performing a cheaper, location-insensitive analysis before proceeding with the full analysis. r? @nikomatsakis
…ramertj Clean up handling of `-Z pgo-gen` commandline option. This PR adapts the `-Z pgo-gen` flag to how Clang and GCC handle the corresponding `-fprofile-generate` flag. In particular, the flag now optionally takes a directory to place the profiling data in and allows to omit the argument (instead of having to pass an empty string).

…t-stack-sizes-gc-sections-ld-gold-bug, r=alexcrichton Revert "compile crates under test w/ -Zemit-stack-sizes" Revert PR rust-lang#59401 to fix issue rust-lang#59652 (a stable-to-beta regression). This is result of squashing two revert commits: Revert "compile all crates under test w/ -Zemit-stack-sizes" This reverts commit 7d365cf. Revert "bootstrap: build compiler-builtins with -Z emit-stack-sizes" This reverts commit 8b8488c. ---- (My intention is that someone can re-add this code again later, either after the `ld.gold` issue itself is fixed, or with safe-guards to check whether `ld.gold` is in use and then issuing warnings about the problems here when they arise.)
