When encountering a typo in a pattern that gets interpreted as an unused binding, look for unit struct/variant of the same type as the binding:
```
error: unused variable: `Non`
--> $DIR/binding-typo-2.rs:36:9
|
LL | Non => {}
| ^^^
|
help: if this is intentional, prefix it with an underscore
|
LL | _Non => {}
| +
help: you might have meant to pattern match on the similarly named variant `None`
|
LL - Non => {}
LL + std::prelude::v1::None => {}
|
```
|
|
|
|
Not all existing tests are converted, I only updated ones that I can
easily find via directive comments.
|
|
```
error[E0610]: `{integer}` is a primitive type and therefore doesn't have fields
--> $DIR/attempted-access-non-fatal.rs:7:15
|
LL | let _ = 2.l;
| ^
|
help: if intended to be a floating point literal, consider adding a `0` after the period and a `f64` suffix
|
LL - let _ = 2.l;
LL + let _ = 2.0f64;
|
```

Done with
```bash
sd '//@ pretty-expanded.*\n' '' tests/ui/**/*.rs
```
and
```
sd '//@pretty-expanded.*\n' '' tests/ui/**/*.rs
```

This test fails on targets without unwinding because the proc macro was
compiled as the target, not the host. Some targets were explicitly
disabled to pass CI, but these directives are more general.
Fixes Fuchsia tests.
|
|
The lint-non-snake-case-crate test may emit a warning in stderr if the
target does not support unwinding
```
warning: building proc macro crate with `panic=abort` may crash the compiler should the proc-macro panic
```
Consequently, the test will fail on targets that don't support unwinding
as written.
This change prevents lint-non-snake-case-crate#proc_macro_ from running
on targets that don't support unwind by using the needs-unwind
directive.

Mainly so that it is easier to only run all `non-snake-case`-specific
tests but no other tests with:
./x test tests/ui/lint/non-snake-case
But also to reduce the size of the large `tests/ui/lint` directory. And
rename some tests to pass tidy, and remove them from
`src/tools/tidy/src/issues.txt`.
