2023-09-11Move let expression checking to parsingMatthew Jasper-1/+1
There was an incomplete version of the check in parsing and a second version in AST validation. This meant that some, but not all, invalid uses were allowed inside macros/disabled cfgs. It also means that later passes have a hard time knowing when the let expression is in a valid location, sometimes causing ICEs. - Add a field to ExprKind::Let in AST/HIR to mark whether it's in a valid location. - Suppress later errors and MIR construction for invalid let expressions.
2023-08-24Auto merge of #115131 - frank-king:feature/unnamed-fields-lite, r=petrochenkovbors-1/+13
Parse unnamed fields and anonymous structs or unions (no-recovery) It is part of #114782 which implements #49804. Only parse anonymous structs or unions in struct field definition positions. r? `@petrochenkov`

2023-08-04Improve spans for indexing expressionsNilstrieb-1/+1
Indexing is similar to method calls in having an arbitrary left-hand-side and then something on the right, which is the main part of the expression. Method calls already have a span for that right part, but indexing does not. This means that long method chains that use indexing have really bad spans, especially when the indexing panics and that span in coverted into a panic location. This does the same thing as method calls for the AST and HIR, storing an extra span which is then put into the `fn_span` field in THIR.
2023-08-03Remove `MacDelimiter`.Nicholas Nethercote-3/+3
It's the same as `Delimiter`, minus the `Invisible` variant. I'm generally in favour of using types to make impossible states unrepresentable, but this one feels very low-value, and the conversions between the two types are annoying and confusing. Look at the change in `src/tools/rustfmt/src/expr.rs` for an example: the old code converted from `MacDelimiter` to `Delimiter` and back again, for no good reason. This suggests the author was confused about the types.

Close parentheses for `offset_of` in AST pretty printing HIR pretty printing already handles it correctly. This will conflict with #110694 but it seems like that PR is gonna take bit more time.

2023-01-26Auto merge of #106745 - m-ou-se:format-args-ast, r=oli-obkbors-0/+104
Move format_args!() into AST (and expand it during AST lowering) Implements https://github.com/rust-lang/compiler-team/issues/541 This moves FormatArgs from rustc_builtin_macros to rustc_ast_lowering. For now, the end result is the same. But this allows for future changes to do smarter things with format_args!(). It also allows Clippy to directly access the ast::FormatArgs, making things a lot easier. This change turns the format args types into lang items. The builtin macro used to refer to them by their path. After this change, the path is no longer relevant, making it easier to make changes in `core`. This updates clippy to use the new language items, but this doesn't yet make clippy use the ast::FormatArgs structure that's now available. That should be done after this is merged.
