If so, we keep that information around. When resolving a path like `foo::bar`, we do not emit any errors for "`bar` not found in `foo`", as we know that the parse error might have caused `bar` to not be parsed and accounted for. When this happens in an existing project, every path referencing `foo` would be an irrelevant compile error. Instead, we now skip emitting anything until `foo.rs` is fixed. Tellingly enough, we didn't have any test for errors caused by `mod` expansion.

It (presumably) intends to include all keywords, but it omits `yeet`. rustfmt has its own explicit list of Rust keywords. It also (presumably) intends to include all keywords, but it omits `await`, `builtin`, `gen`, `macro_rules`, `raw`, `reuse`, `safe`, and `yeet`. Also, it does linear searches through this list, which is inefficient. This commit fixes all of the above problems by introducing a new predicate `is_any_keyword` in rustc and using it in rustdoc and rustfmt. It documents that it's not the right predicate in most cases. --- compiler/rustc_ast/src/token.rs | 8 ++- compiler/rustc_parse/src/parser/diagnostics.rs | 4 +- compiler/rustc_span/src/symbol.rs | 10 +++ src/tools/rustfmt/src/parse/macros/mod.rs | 87 ++++---------------------- 4 files changed, 31 insertions(+), 78 deletions(-) (limited to 'src/tools') diff --git a/compiler/rustc_ast/src/token.rs b/compiler/rustc_ast/src/token.rs index ab82f18133e..f639e785bc4 100644 --- a/compiler/rustc_ast/src/token.rs +++ b/compiler/rustc_ast/src/token.rs @@ -903,7 +903,8 @@ impl Token { self.is_non_raw_ident_where(|id| id.name == kw) } - /// Returns `true` if the token is a given keyword, `kw` or if `case` is `Insensitive` and this token is an identifier equal to `kw` ignoring the case. + /// Returns `true` if the token is a given keyword, `kw` or if `case` is `Insensitive` and this + /// token is an identifier equal to `kw` ignoring the case. pub fn is_keyword_case(&self, kw: Symbol, case: Case) -> bool { self.is_keyword(kw) || (case == Case::Insensitive @@ -916,6 +917,11 @@ impl Token { self.is_non_raw_ident_where(Ident::is_path_segment_keyword) } + /// Don't use this unless you're doing something very loose and heuristic-y. + pub fn is_any_keyword(&self) -> bool { + self.is_non_raw_ident_where(Ident::is_any_keyword) + } + /// Returns true for reserved identifiers used internally for elided lifetimes, /// unnamed method parameters, crate root module, error recovery etc. pub fn is_special_ident(&self) -> bool { diff --git a/compiler/rustc_parse/src/parser/diagnostics.rs b/compiler/rustc_parse/src/parser/diagnostics.rs index 9b335df6c0f..8417701ac0c 100644 --- a/compiler/rustc_parse/src/parser/diagnostics.rs +++ b/compiler/rustc_parse/src/parser/diagnostics.rs @@ -815,8 +815,8 @@ impl<'a> Parser<'a> { // Otherwise, check the previous token with all the keywords as possible candidates. // This handles code like `Struct Human;` and `While a < b {}`. - // We check the previous token only when the current token is an identifier to avoid false - // positives like suggesting keyword `for` for `extern crate foo {}`. + // We check the previous token only when the current token is an identifier to avoid + // false positives like suggesting keyword `for` for `extern crate foo {}`. if let Some(misspelled_kw) = find_similar_kw(prev_ident, &all_keywords) { err.subdiagnostic(misspelled_kw);

The parser pushes a `TokenType` to `Parser::expected_token_types` on every call to the various `check`/`eat` methods, and clears it on every call to `bump`. Some of those `TokenType` values are full tokens that require cloning and dropping. This is a *lot* of work for something that is only used in error messages and it accounts for a significant fraction of parsing execution time. This commit overhauls `TokenType` so that `Parser::expected_token_types` can be implemented as a bitset. This requires changing `TokenType` to a C-style parameterless enum, and adding `TokenTypeSet` which uses a `u128` for the bits. (The new `TokenType` has 105 variants.) The new types `ExpTokenPair` and `ExpKeywordPair` are now arguments to the `check`/`eat` methods. This is for maximum speed. The elements in the pairs are always statically known; e.g. a `token::BinOp(token::Star)` is always paired with a `TokenType::Star`. So we now compute `TokenType`s in advance and pass them in to `check`/`eat` rather than the current approach of constructing them on insertion into `expected_token_types`. Values of these pair types can be produced by the new `exp!` macro, which is used at every `check`/`eat` call site. The macro is for convenience, allowing any pair to be generated from a single identifier. The ident/keyword filtering in `expected_one_of_not_found` is no longer necessary. It was there to account for some sloppiness in `TokenKind`/`TokenType` comparisons. The existing `TokenType` is moved to a new file `token_type.rs`, and all its new infrastructure is added to that file. There is more boilerplate code than I would like, but I can't see how to make it shorter. --- compiler/rustc_builtin_macros/src/asm.rs | 112 ++-- compiler/rustc_builtin_macros/src/assert.rs | 3 +- compiler/rustc_builtin_macros/src/cfg.rs | 5 +- compiler/rustc_builtin_macros/src/format.rs | 7 +- compiler/rustc_builtin_macros/src/pattern_type.rs | 5 +- compiler/rustc_builtin_macros/src/util.rs | 6 +- compiler/rustc_expand/src/module.rs | 6 +- compiler/rustc_expand/src/proc_macro_server.rs | 4 +- compiler/rustc_parse/src/parser/attr.rs | 41 +- compiler/rustc_parse/src/parser/diagnostics.rs | 139 ++--- compiler/rustc_parse/src/parser/expr.rs | 308 ++++++----- compiler/rustc_parse/src/parser/generics.rs | 33 +- compiler/rustc_parse/src/parser/item.rs | 370 ++++++------- compiler/rustc_parse/src/parser/mod.rs | 226 ++++---- compiler/rustc_parse/src/parser/pat.rs | 77 +-- compiler/rustc_parse/src/parser/path.rs | 34 +- compiler/rustc_parse/src/parser/stmt.rs | 27 +- compiler/rustc_parse/src/parser/token_type.rs | 620 ++++++++++++++++++++++ compiler/rustc_parse/src/parser/ty.rs | 92 ++-- src/tools/rustfmt/src/parse/macros/cfg_if.rs | 11 +- src/tools/rustfmt/src/parse/macros/lazy_static.rs | 17 +- src/tools/rustfmt/src/parse/parser.rs | 5 +- 22 files changed, 1356 insertions(+), 792 deletions(-) create mode 100644 compiler/rustc_parse/src/parser/token_type.rs (limited to 'src/tools') diff --git a/compiler/rustc_builtin_macros/src/asm.rs b/compiler/rustc_builtin_macros/src/asm.rs index cce70fb2ea4..6ae697d4030 100644 --- a/compiler/rustc_builtin_macros/src/asm.rs +++ b/compiler/rustc_builtin_macros/src/asm.rs @@ -1,16 +1,16 @@ use ast::token::IdentIsRaw;
