2024-12-19Speed up `Parser::expected_token_types`.Nicholas Nethercote-16/+17
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.

This change moves it there to reduce complexity of `compile::Assemble` logic. Signed-off-by: onur-ozkan <work@onurozkan.dev>

2024-12-18Only have one source of truth for keywords.Nicholas Nethercote-75/+12
`rustc_symbol` is the source of truth for keywords. rustdoc has its own implicit definition of keywords, via the `is_doc_keyword`. 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.
