2023-11-02Minimize `pub` usage in `source_map.rs`.Nicholas Nethercote-1/+2
Most notably, this commit changes the `pub use crate::*;` in that file to `use crate::*;`. This requires a lot of `use` items in other crates to be adjusted, because everything defined within `rustc_span::*` was also available via `rustc_span::source_map::*`, which is bizarre. The commit also removes `SourceMap::span_to_relative_line_string`, which is unused.

2023-09-11Move let expression checking to parsingMatthew Jasper-2/+4
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.

2023-08-04Auto merge of #112117 - bryangarza:track-caller-feature-gate, r=compiler-errorsbors-2/+2
Add separate feature gate for async fn track caller This patch adds a feature gate `async_fn_track_caller` that is separate from `closure_track_caller`. This is to allow enabling `async_fn_track_caller` separately. Fixes #110009
2023-08-04Improve spans for indexing expressionsNilstrieb-2/+2
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.

2023-04-16Alloc `hir::Lit` in an arena to remove the destructor from `Expr`Nilstrieb-30/+25
This allows allocating `Expr`s into a dropless arena, which is useful for using length prefixed thing slices in HIR, since these can only be allocated in the dropless arena and not in a typed arena. This is something I'm working on.

2023-03-14Auto merge of #104833 - Swatinem:async-identity-future, r=compiler-errorsbors-37/+27
Remove `identity_future` indirection This was previously needed because the indirection used to hide some unexplained lifetime errors, which it turned out were related to the `min_choice` algorithm. Removing the indirection also solves a couple of cycle errors, large moves and makes async blocks support the `#[track_caller]`annotation. Fixes https://github.com/rust-lang/rust/issues/104826.

2023-01-26Auto merge of #106745 - m-ou-se:format-args-ast, r=oli-obkbors-6/+82
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.
