When suggesting an appropriate mutability for a macro call, use the call
span instead of the expanded macro's span.

Remove unused macros from the codebase
Thanks to the lint I've implemented in #41907 I've found some unused macros inside the rustc codebase.
|
|
Removes unused macros from:
* libcore
* libcollections
The last use of these two macros was removed in commit
b64c9d56700e2c41207166fe8709711ff02488ff
when the char_range_at_reverse function was been removed.
* librustc_errors
Their last use was removed by commits
2f2c3e178325dc1837badcd7573c2c0905fab979
and 11dc974a38fd533aa692cea213305056cd3a6902.
* libsyntax_ext
* librustc_trans
Also, put the otry macro in back/msvc/mod.rs under the
same cfg argument as the places that use it.

Don't print the source code in emit_message_default() and
render_source_line() if the source code is None.

When a span starts on a line with nothing but whitespace to the left,
and there are no other annotations in that line, simplify the visual
representation of the span.
Go from:
```rust
error[E0072]: recursive type `A` has infinite size
--> file2.rs:1:1
|
1 | struct A {
| _^ starting here...
2 | | a: A,
3 | | }
| |_^ ...ending here: recursive type has infinite size
|
```
To:
```rust
error[E0072]: recursive type `A` has infinite size
--> file2.rs:1:1
|
1 | / struct A {
2 | | a: A,
3 | | }
| |_^ recursive type has infinite size
```
Remove `starting here...`/`...ending here` labels from all multiline
diagnostics.
|
|
```rust
error[E0046]: not all trait items implemented, missing: `Item`

... |
36 | | }
37 | | }
| |_________^ ...ending here: missing `Item` in implementation
|
= note: `Item` from trait: `type Item;`
```
instead of
```rust
error[E0046]: not all trait items implemented, missing: `Item`
--> $DIR/issue-23729.rs:20:9
|
20 | impl Iterator for Recurrence {
| ^ missing `Item` in implementation

Fix multiple labels when some don't have message
The diagnostic emitter now accounts for labels with no text message, presenting the underline on its own, without drawing the line for the non existing message below it. Go from
```
error: foo
--> test.rs:3:6
|
3 | a { b { c } d }
| ----^^^^^^^----
| | |
| | `b` is a good letter
|
```
to
```
error: foo
--> test.rs:3:6
|
3 | a { b { c } d }
| ----^^^^^^^----
| |
| `b` is a good letter
```
from
```
error: foo
--> test.rs:3:6
|
3 | a { b { c } d }
| ^^^^-------^^^^
| | |
| |
| `a` is a good letter
```
to
```
error: foo
--> test.rs:3:6
|
3 | a { b { c } d }
| ^^^^-------^^^^ `a` is a good letter
```
and from
```
error: foo
--> test.rs:3:6
|
3 | a { b { c } d }
| ^^^^-------^^^^
| | |
| |
|
```
to
```
error: foo
--> test.rs:3:6
|
3 | a { b { c } d }
| ^^^^-------^^^^
```

Make any diagnostic line to have the correct margin to align with the
first line:
```
error: message
--> file.rs:3:20
|
3 | <CODE>
| ^^^^
|
= note: this is a multiline
note with a correct
margin
= note: this is a single line note
= help: here are some functions which might fulfill your needs:
- .len()
- .foo()
- .bar()
= suggestion: this is a multiline
suggestion with a
correct margin
```
|
|
|
|
Make the suggestion list have a correct padding:
```
error[E0308]: mismatched types
--> file.rs:3:20
|
3 | let x: usize = "";
| ^^ expected usize, found reference
|
= note: expected type `usize`
= note: found type `&'static str`
= help: here are some functions which might fulfill your needs:
- .len()
- .foo()
- .bar()
```

When dealing with multiline spans that span few lines, show the complete
span instead of restricting to the first character of the first line.
For example, instead of:
```
% ./rustc foo.rs
error[E0277]: the trait bound `{integer}: std::ops::Add<()>` is not satisfied
--> foo.rs:13:9
|
13 | foo(1 + bar(x,
| ^ trait `{integer}: std::ops::Add<()>` not satisfied
|
```
show
```
% ./rustc foo.rs
error[E0277]: the trait bound `{integer}: std::ops::Add<()>` is not satisfied
--> foo.rs:13:9
|
13 | foo(1 + bar(x,
| ________^ starting here...
14 | | y),
| |_____________^ ...ending here: trait `{integer}: std::ops::Add<()>` not satisfied
|
```
|
|
|
|
Allows replacing stderr with a buffer from the client.
Also, some refactoring around run_compiler.
