They are only used by rustc_lexer, and are not needed elsewhere.
So we move the relevant definitions into rustc_lexer (while the actual
unicode data comes from the unicode-xid crate) and make the rest of
the compiler use it.
On `format!()` arg count mismatch provide extra info
When positional width and precision formatting flags are present in a
formatting string that has an argument count mismatch, provide extra
information pointing at them making it easiser to understand where the
problem may lay:
```
error: 4 positional arguments in format string, but there are 3 arguments
--> $DIR/ifmt-bad-arg.rs:78:15
|
LL | println!("{} {:.*} {}", 1, 3.2, 4);
| ^^ ^^--^ ^^ --- this parameter corresponds to the precision flag
| |
| this precision flag adds an extra required argument at position 1, which is why there are 4 arguments expected
|

I think this was left out by accident from the "convert everything to
rlibs" commit, there's no need for this to be a dylib just as everything
else doesn't need to be a dylib!
Now that procedural macros no longer link transitively to libsyntax,
this shouldn't be needed any more! This commit is an experiment in
removing all dynamic libraries from rustc except for librustc_driver
itself. Let's see how far we can get with that!
Use Symbol, Span in libfmt_macros
I'm not super happy with this, personally, but I think it might be a decent start -- happy to take suggestions as to how to expand this or change things further.
r? @estebank
Fixes#60795
This should be used when trying to get at subsets of a larger span,
especially when the larger span is not available in the code attempting
to work with those subsets (especially common in the fmt_macros crate).
This is usually a good replacement for (BytePos, BytePos) and (usize,
usize) tuples.
This commit also removes from_inner_byte_pos, since it took usize
arguments, which is error prone.
Fix some minor warnings
Since apparently RLS works when initialized in the root repository (🎉) I decided to fix some of the issues it caught.
There are a lot of unused attribute warnings left on `rustc_on_unimplemented` and `rustc_layout_scalar_valid_range_start` but I imagine we can't do much about it due to 2-stage compilation?
When a format string has escaped whitespace characters format
arguments were shifted by one per each escaped character. Account
for these escaped characters when synthesizing the spans.
Fix#55155.
- Point at opening mismatched formatting brace
- Account for differences between raw and regular strings
- Account for differences between the code snippet and `InternedString`
- Add more tests
Rollup of bare_trait_objects PRs
All deny attributes were moved into bootstrap so they can be disabled with a line of config.
Warnings for external tools are allowed and it's up to the tool's maintainer to keep it warnings free.
r? @Mark-Simulacrum

When encountering format string errors in a raw string, or regular
string literal with embedded newlines, account for the positional
change to use correct spans.
