2025-08-26Remove 1-argument special case from format_args!().Mara Bos-20/+0
The argument needs to be lifetime-extended, so this special case isn't actually perfectly equivalent to the general case.

2025-06-19Use expr_ref.Mara Bos-2/+1
2025-06-18Fix span of AddrOf in format_args!() expansion.Mara Bos-1/+1
Diagnostics should know that the `&` for arguments in format_args!() come from the macro expansion rather than from the original source.
2025-06-18Allow storing `format_args!()` in `let`.Mara Bos-129/+78
This uses `super let` to allow let f = format_args!("Hello {}", world); println!("{f}"); to work.
2025-05-22Rename `kw::Empty` as `sym::empty`.Nicholas Nethercote-2/+2
Because the empty string is not a keyword.
2025-03-30Simplify expansion for format_args!().Mara Bos-15/+13
Instead of calling new(), we can just use a struct expression directly. Before: Placeholder::new(…, …, …, …) After: Placeholder { position: …, flags: …, width: …, precision: …, }

2024-12-18Re-export more `rustc_span::symbol` things from `rustc_span`.Nicholas Nethercote-2/+1
`rustc_span::symbol` defines some things that are re-exported from `rustc_span`, such as `Symbol` and `sym`. But it doesn't re-export some closely related things such as `Ident` and `kw`. So you can do `use rustc_span::{Symbol, sym}` but you have to do `use rustc_span::symbol::{Ident, kw}`, which is inconsistent for no good reason. This commit re-exports `Ident`, `kw`, and `MacroRulesNormalizedIdent`, and changes many `rustc_span::symbol::` qualifiers in `compiler/` to `rustc_span::`. This is a 200+ net line of code reduction, mostly because many files with two `use rustc_span` items can be reduced to one.

2024-08-28fmt-debug optionKornel-2/+6
Allows disabling `fmt::Debug` derive and debug formatting.
2024-07-29Reformat `use` declarations.Nicholas Nethercote-9/+7
The previous commit updated `rustfmt.toml` appropriately. This commit is the outcome of running `x fmt --all` with the new formatting options.

2023-12-24Remove `Session` methods that duplicate `DiagCtxt` methods.Nicholas Nethercote-2/+2
Also add some `dcx` methods to types that wrap `TyCtxt`, for easier access.
2023-12-10remove redundant importssurechen-1/+1
detects redundant imports that can be eliminated. for #117772 : In order to facilitate review and modification, split the checking code and removing redundant imports code into two PR.
2023-12-02Rename `HandlerInner::delay_span_bug` as `HandlerInner::span_delayed_bug`.Nicholas Nethercote-2/+2
Because the corresponding `Level` is `DelayedBug` and `span_delayed_bug` follows the pattern used everywhere else: `span_err`, `span_warning`, etc.
2023-11-21Fix `clippy::needless_borrow` in the compilerNilstrieb-2/+2
`x clippy compiler -Aclippy::all -Wclippy::needless_borrow --fix`. Then I had to remove a few unnecessary parens and muts that were exposed now.

2023-10-03Optimize some `alloc_from_iter` call sites.Nicholas Nethercote-29/+18
There's no need to collect an iterator into a `Vec`, or to call `into_iter` at the call sites.
2023-05-09Limit lifetime of format_args!() with inlined args.Mara Bos-1/+24
2023-05-01Rollup merge of #110823 - compiler-errors:tweak-await-span, r=b-naberMatthias Krüger-1/+1
Tweak await span to not contain dot Fixes a discrepancy between method calls and await expressions where the latter are desugared to have a span that *contains* the dot (i.e. `.await`) but method call identifiers don't contain the dot. This leads to weird suggestions suggestions in borrowck -- see linked issue. Fixes #110761 This mostly touches a bunch of tests to tighten their `await` span.
