Auto merge of #142487 - estebank:serde-attr-5, r=petrochenkov
Detect missing `derive` on unresolved attribute even when not imported
When encountering unresolved attributes, ensure the proc-macros for every crate in scope are added to the `macro_map` so that typos and missing `derive`s are properly detected.
```
error: cannot find attribute `sede` in this scope
--> $DIR/missing-derive-3.rs:20:7
|
LL | #[sede(untagged)]
| ^^^^
|
help: the derive macros `Deserialize` and `Serialize` accept the similarly named `serde` attribute
|
LL | #[serde(untagged)]
| +
error: cannot find attribute `serde` in this scope
--> $DIR/missing-derive-3.rs:14:7
|
LL | #[serde(untagged)]
| ^^^^^
|
note: `serde` is imported here, but it is a crate, not an attribute
--> $DIR/missing-derive-3.rs:4:1
|
LL | extern crate serde;
| ^^^^^^^^^^^^^^^^^^^
help: `serde` is an attribute that can be used by the derive macros `Deserialize` and `Serialize`, you might be missing a `derive` attribute
|
LL + #[derive(Deserialize, Serialize)]
LL | enum B {
|
```
Follow up to rust-lang/rust#134841. Fix rust-lang/rust#47608.
