Convert cfg syntax to new system This removes the ability to use `foo(bar)` style cfgs. Switch them to `foo_bar` or `foo="bar"` instead. [breaking-change] 2014-09-24 20:22:57 -07:00			`#[cfg(all(foo, bar))] // foo AND bar`
Detect more `cfg`d out items in resolution errors Use a visitor to collect all items (including those nested) that were stripped behind a `cfg` condition. ``` error[E0425]: cannot find function `f` in this scope --> $DIR/nested-cfg-attrs.rs:4:13 \| LL \| fn main() { f() } \| ^ not found in this scope \| note: found an item that was configured out --> $DIR/nested-cfg-attrs.rs:2:4 \| LL \| fn f() {} \| ^ note: the item is gated here --> $DIR/nested-cfg-attrs.rs:1:35 \| LL \| #[cfg_attr(all(), cfg_attr(all(), cfg(FALSE)))] \| ^^^^^^^^^^ ``` 2024-08-17 05:45:10 +00:00			`//~^ NOTE the item is gated here`
