Implement builtin # syntax and use it for offset_of!(...) Add `builtin #` syntax to the parser, as well as a generic infrastructure to support both item and expression position builtin syntaxes. The PR also uses this infrastructure for the implementation of the `offset_of!` macro, added by #106934. cc `@petrochenkov` `@DrMeepster` cc #110680 `builtin #` tracking issue cc #106655 `offset_of!` tracking issue

2023-05-06Rollup merge of #111230 - zacklukem:eq-less-to-less-eq, r=compiler-errorsMatthias Krüger-1/+12
add hint for =< as <= Adds a compiler hint for when `=<` is typed instead of `<=` Example hint: ```rust fn foo() { if 1 =< 3 { println!("Hello, World!"); } } ``` ``` error: expected type, found `3` --> main.rs:2:13 | 2 | if 1 =< 3 { | -- ^ expected type | | | help: did you mean: `<=` ``` This PR only emits the suggestion if there is no space between the `=` and `<`. This hopefully narrows the scope of when this error is emitted, however this still allows this error to be emitted in cases such as this: ``` error: expected expression, found `;` --> main.rs:2:18 | 2 | if 1 =< [i32;; 3]>::hello() { | -- ^ expected expression | | | help: did you mean: `<=` ``` Which could be a good reason not to merge since I haven't been able to think of any other ways of narrowing the scope of this diagnostic. closes #111128

2023-05-04Rollup merge of #110791 - compiler-errors:negative-bounds, r=oli-obkDylan DPC-125/+59
Implement negative bounds for internal testing purposes Implements partial support the `!` negative polarity on trait bounds. This is incomplete, but should allow us to at least be able to play with the feature. Not even gonna consider them as a public-facing feature, but I'm implementing them because would've been nice to have in UI tests, for example in #110671.
2023-05-03Restrict `From<S>` for `{D,Subd}iagnosticMessage`.Nicholas Nethercote-51/+47
Currently a `{D,Subd}iagnosticMessage` can be created from any type that impls `Into<String>`. That includes `&str`, `String`, and `Cow<'static, str>`, which are reasonable. It also includes `&String`, which is pretty weird, and results in many places making unnecessary allocations for patterns like this: ``` self.fatal(&format!(...)) ``` This creates a string with `format!`, takes a reference, passes the reference to `fatal`, which does an `into()`, which clones the reference, doing a second allocation. Two allocations for a single string, bleh. This commit changes the `From` impls so that you can only create a `{D,Subd}iagnosticMessage` from `&str`, `String`, or `Cow<'static, str>`. This requires changing all the places that currently create one from a `&String`. Most of these are of the `&format!(...)` form described above; each one removes an unnecessary static `&`, plus an allocation when executed. There are also a few places where the existing use of `&String` was more reasonable; these now just use `clone()` at the call site. As well as making the code nicer and more efficient, this is a step towards possibly using `Cow<'static, str>` in `{D,Subd}iagnosticMessage::{Str,Eager}`. That would require changing the `From<&'a str>` impls to `From<&'static str>`, which is doable, but I'm not yet sure if it's worthwhile.

2023-05-01Rollup merge of #110823 - compiler-errors:tweak-await-span, r=b-naberMatthias Krüger-3/+3
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.

2023-04-19Auto merge of #110407 - Nilstrieb:fluent-macro, r=davidtwcobors-1/+2
Add `rustc_fluent_macro` to decouple fluent from `rustc_macros` Fluent, with all the icu4x it brings in, takes quite some time to compile. `fluent_messages!` is only needed in further downstream rustc crates, but is blocking more upstream crates like `rustc_index`. By splitting it out, we allow `rustc_macros` to be compiled earlier, which speeds up `x check compiler` by about 5 seconds (and even more after the needless dependency on `serde_json` is removed from `rustc_data_structures`).

Remove `..` from return type notation `@nikomatsakis` and I decided that using `..` in the return-type notation syntax is probably overkill. r? `@eholk` since you reviewed the last one Since this is piggybacking now totally off of a pre-existing syntax (parenthesized generics), let me know if you need any explanation of the logic here, since it's a bit more complicated now.
