2019-09-15Give more `Idents` spansMatthew Jasper-4/+4
2019-08-23Audit uses of `apply_mark` in built-in macrosVadim Petrochenkov-1/+1
Replace them with equivalents of `Span::{def_site,call_site}` from proc macro API. The new API is much less error prone and doesn't rely on macros having default transparency.
2019-08-17Remove gensyms from built-in derivesMatthew Jasper-4/+4
Also make them generally more hygienic with name resolution.
2019-08-15`Ident::with_empty_ctxt` -> `Ident::with_dummy_span`Vadim Petrochenkov-2/+2
`Ident` has had a full span rather than just a `SyntaxContext` for a long time now.

2019-05-27Avoid unnecessary internings.Nicholas Nethercote-2/+3
Most involving `Symbol::intern` on string literals.
2019-04-21Introduce `LocalSource` into the AST.David Wood-0/+1
This will be used to keep track of the origin of a local in the AST. In particular, it will be used by `async fn` lowering for the locals in `let <pat>: <ty> = __arg0;` statements.

2018-04-06Rename `ast::Variant_::name` into `ident` + Fix rebaseVadim Petrochenkov-1/+1
2018-03-11Fix hygene issue when deriving DebugPhlosioneer-1/+1
The code for several of the core traits doesn't use hygenic macros. This isn't a problem, except for the Debug trait, which is the only one that uses a variable, named "builder". Variables can't share names with unit structs, so attempting to [derive(Debug)] on any type while a unit struct with the name "builder" was in scope would result in an error. This commit just changes the name of the variable to "__debug_trait_builder", because I couldn't figure out how to get a list of all unit structs in-scope from within the derive expansion function. If someone wants to have a unit struct with the exact name "__debug_trait_builder", they'll just have to do it without a [derive(Debug)].

2016-06-26Rollup merge of #34436 - jseyfried:no_block_expr, r=eddybJeffrey Seyfried-2/+3
To allow these braced macro invocation, this PR removes the optional expression from `ast::Block` and instead uses a `StmtKind::Expr` at the end of the statement list. Currently, braced macro invocations in blocks can expand into statements (and items) except when they are last in a block, in which case they can only expand into expressions. For example, ```rust macro_rules! make_stmt { () => { let x = 0; } } fn f() { make_stmt! {} //< This is OK... let x = 0; //< ... unless this line is commented out. } ``` Fixes #34418.
2016-06-26Rollup merge of #34339 - jseyfried:thin_vec, r=petrochenkov,ManishearthJeffrey Seyfried-1/+1
Generalize and abstract `ThinAttributes` to `ThinVec<Attribute>`.
2016-06-26Rollup merge of #34316 - jseyfried:refactor_ast_stmt, r=eddybJeffrey Seyfried-3/+5
Refactor away `ast::Decl`, refactor `ast::Stmt`, and rename `ast::ExprKind::Again` to `ast::ExprKind::Continue`.

2016-05-12Improve derived implementations for enums with lots of fieldless variantsBjörn Steinbrink-0/+1
A number of trait methods like PartialEq::eq or Hash::hash don't actually need a distinct arm for each variant, because the code within the arm only depends on the number and types of the fields in the variants. We can easily exploit this fact to create less and better code for enums with multiple variants that have no fields at all, the extreme case being C-like enums. For nickel.rs and its by now infamous 800 variant enum, this reduces optimized compile times by 25% and non-optimized compile times by 40%. Also peak memory usage is down by almost 40% (310MB down to 190MB). To be fair, most other crates don't benefit nearly as much, because they don't have as huge enums. The crates in the Rust distribution that I measured saw basically no change in compile times (I only tried optimized builds) and only 1-2% reduction in peak memory usage.
