…th 1 when reaching end
These have been bugging me for a while. - `literal_text`: `src` is also used and is shorter and better. - `first_char`: used even when "first" doesn't make sense; `c` is shorter and better. - `curr`: `c` is shorter and better. - `unescaped_char`: `result` is also used and is shorter and better. - `second_char`: these have a single use and can be elided.
There is some subtlety here.
It's passed to numerous places where we just need an `is_byte` bool. Passing the bool avoids the need for some assertions. Also rename `is_bytes()` as `is_byte()`, to better match `Mode::Byte`, `Mode::ByteStr`, and `Mode::RawByteStr`.
There are three kinds of "byte" literals: byte literals, byte string literals, and raw byte string literals. None are allowed to have non-ASCII chars in them. Two `EscapeError` variants exist for when that constraint is violated. - `NonAsciiCharInByte`: used for byte literals and byte string literals. - `NonAsciiCharInByteString`: used for raw byte string literals. As a result, the messages for raw byte string literals use different wording, without good reason. Also, byte string literals are incorrectly described as "byte constants" in some error messages. This commit eliminates `NonAsciiCharInByteString` so the three cases are handled similarly, and described correctly. The `mode` is enough to distinguish them. Note: Some existing error messages mention "byte constants" and some mention "byte literals". I went with the latter here, because it's a more correct name, as used by the Reference.
Remove a low-value comment, remove a duplicate comment, and correct a third comment.
It deals with eight cases: ints, floats, and the six quoted types (char/byte/strings). For ints and floats we have an early return, and the other six types fall through to the code at the end, which makes the function hard to read. This commit rearranges things to avoid the early returns.
It has a single callsite, and is fairly small. The `Float` match arm already has base-specific checking inline, so this makes things more consistent.
It's easy to just use `unescape_literal` + `byte_from_char`.
This option prints all supported values for -Csplit-debuginfo=.., i.e. only stable ones on stable/beta and all of them on nightly/dev.
fix: lint against the functions `LintContext::{lookup_with_diagnostics,lookup,struct_span_lint,lint}`, `TyCtxt::struct_lint_node`, `LintLevelsBuilder::struct_lint`.
The `usize` isn't needed in the error case.
…-hang, r=jackh726,wesleywiser Avoid possible infinite loop when next_point reaching the end of file Fixes rust-lang#103451 If we return a span with `lo` = `hi`, `span_to_snippet` will always get `Ok("")`, which may introduce infinite loop if we don't care. This PR make `find_width_of_character_at_span` return `width` with 1, so that `span_to_snippet` will get an `Err`.
…Simulacrum Upgrade cc for working is_flag_supported on cross-compiles rust-lang#85806 fixed unwind v.s gcc support on later Android ndks using `is_flag_supported`. However, due to rust-lang/cc-rs#675, this didn't work properly on cross-compiles. rust-lang/cc-rs@3eeb50b fixes this, and was released in cc 1.0.74, hence the upgrade

…ce, r=Mark-Simulacrum Don't intra linkcheck reference This removes the reference from the intra-doc link checks. This causes problems if any of the reference content needs to change, it causes the linkchecker to break. The reference has its own broken link check (https://github.com/rust-lang/reference/tree/master/style-check) which uses pulldown-cmark on the source to find actual broken links (instead of false-positives like this regex does). I think the intra-doc link check could potentially be removed completely, since I think rustdoc is now checking for them well enough. However, it may serve as a decent regression check.
Place config.toml in current working directory if config not found
Fixes an issue where bootsrapping a Rust build would place `config.toml` in `{src_root}` rather than the current working directory
rust-lang#103697
Add split-debuginfo print option This option prints all supported values for `-Csplit-debuginfo=..`, i.e. only stable ones on stable/beta and all of them on nightly/dev. Motivated by 1.65.0 regression causing builds with the following entry in `Cargo.toml` to fail on Windows: ```toml [profile.dev] split-debuginfo = "unpacked" ``` See rust-lang/cargo#11347 for details. This will lead to closing rust-lang#103976.

…th, r=notriddle Fix invalid background-image file name This is a follow-up of rust-lang#101702. Apparently the image hash was the wrong one. You can see the error in https://doc.rust-lang.org/nightly/core/primitive.u16.html?search=hello too. I really need to check if I can adds check for resources load errors in `browser-ui-test`. cc `````@jsha````` r? `````@notriddle`````

…pnkfelix Clarify licensing situation of MPSC and SPSC queue Originally, these two files were licensed under the `BSD-2-Clause` license, as they were based off sample code on a blog licensing those snippets under that license: * `library/std/src/sync/mpsc/mpsc_queue.rs` * `library/std/src/sync/mpsc/spsc_queue.rs` In 2017 though, the author of that blog agreed to relicense their code under the standard `MIT OR Apache-2.0` license in rust-lang#42149. This PR clarifies the situation in the files by expanding the comment at the top of the file. r? `@pnkfelix`
