|\ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 1928: Support `#[cfg(..)]` r=matklad a=oxalica This PR implement `#[cfg(..)]` conditional compilation. It read default cfg options from `rustc --print cfg` with also hard-coded `test` and `debug_assertion` enabled. Front-end settings are **not** included in this PR. There is also a known issue that inner control attributes are totally ignored. I think it is **not** a part of `cfg` and create a separated issue for it. #1949 Fixes #1920 Related: #1073 Co-authored-by: uHOOCCOOHu <[email protected]> Co-authored-by: oxalica <[email protected]>

|\ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 1815: Support correct `$crate` expansion in macros r=uHOOCCOOHu a=uHOOCCOOHu This PR makes normal use cases of `$crate` from macros work as expected. It makes more macros from `std` work. Type inference works well with `panic`, `unimplemented`, `format`, and maybe more. Sadly that `vec![1, 2, 3]` still not works, but it is not longer an issue about macro.

* Handle associated type shorthand (`T::Item`)Florian Diebold2019-09-222-17/+144
| | | | | | | | | | | | This is only allowed for generic parameters (including `Self` in traits), and special care needs to be taken to not run into cycles while resolving it, because we use the where clauses of the generic parameter to find candidates for the trait containing the associated type, but the where clauses may themselves contain instances of short-hand associated types. In some cases this is even fine, e.g. we might have `T: Trait<U::Item>, U: Iterator`. If there is a cycle, we'll currently panic, which isn't great, but better than overflowing the stack...

|
* Refactor some moreFlorian Diebold2019-09-172-49/+85
| | | | | | Type-relative paths (`<T>::foo`) also need to work in type context, for example `<T>::Item` is legal. So rather than returning the type ref from the resolver function, just check it before.
* Refactor associated item resolution moreFlorian Diebold2019-09-172-124/+120
| | | | | When resolving an associated item in value namespace, use the `Ty` lowering code for the segments before the last instead of replicating it.

|
* Resolve assoc types on type parametersFlorian Diebold2019-09-172-24/+61
| | | | | | E.g. `fn foo<T: Iterator>() -> T::Item`. It seems that rustc does this only for type parameters and only based on their bounds, so we also only consider traits from bounds.
