Currently hex/octal/binary literals with computed values are displayed
like `0_xff_fff_fffu32`, which is invalid since underscores can't be in
the middle of integer prefixes. This properly formats prefixed integers.
- It's used exactly once, so it's trivial to replace
- It doesn't match the normal convention for containers: normally
`get()` returns and option and indexing panics. Instead `get()` panicked
and there's no indexing operation available.
This updates the documentation since `ptr::addr_of!` and
`ptr::addr_of_mut!` are now stable. One might remove the distinction
between the sections `# On packed structs` and `# Examples`, as the old
section on packed structs was primarily to prevent users of doing unde-
fined behavior, which is not necessary anymore.
There is also a new section in "how to obtain a pointer", which referen-
ces the `ptr::addr_of!` macros.

Currently, we have LLVM tarballs for win64, generated by someone running
the installer via wine and tarring up the result.
7z knows how to extract NSIS installers directly, and the result is
identical to our tarball, except that it doesn't include `Uninstall.exe`
(which we don't care about) and it includes the NSIS plugin directory
(which we also don't care about).
This simplifies the process of upgrading CI, and allows us to just
mirror the upstream release .exe directly. This also improves our
supply chain.
This extracts a new `parse_cfg` function that's used between both.
- Treat `#[doc(cfg(x), cfg(y))]` the same as `#[doc(cfg(x)]
#[doc(cfg(y))]`. Previously it would be completely ignored.
- Treat `#[doc(inline, cfg(x))]` the same as `#[doc(inline)]
#[doc(cfg(x))]`. Previously, the cfg would be ignored.
- Pass the cfg predicate through to rustc_expand to be validated

[single_char_pattern] add strip_prefix and strip_suffix
Title says it all. Adjusted ui tests.
I added the second commit in case you don't like that I moved that table into `single_char_pattern.rs` directly. I don't see any reason why it shouldn't be in that file. It isn't used anywhere else.
*Please write a short comment explaining your change (or "none" for internal only changes)*
changelog: add strip_prefix and strip_suffix to single_char_pattern lint
`Conf` macro improvements part 2
changelog: none
Follow-up to #7150
I made the default value required again for `define_Conf!` so that it can be parsed by the magic Python. I guess it's just as well for readability.
r? `@flip1995`
MinGW driver for COFF LLD doesn't currently translate GNU-style `--threads=N` to native `/threads:N`, so we have to pass the option in its native form to avoid an error.
Also pass the `threads` flag to lld-link as well
Change librustdoc write!(.. \n) to writeln!(..); fix comment grammar
Howdy,
This PR does the following:
1. Updates the grammar of a comment in librustdoc.
2. Replaces a few write!(..\n) macros with writeln!(..\n) for clarity. (Please let me know if there is a reason why this might be wrong!)
Best,
Mautamu
parser: Remove support for inner attributes on non-block expressions
Remove support for attributes like
```rust
fn attrs() {
(#![print_target_and_args(fifth)] 1, 2);
[#![print_target_and_args(sixth)] 1 , 2];
[#![print_target_and_args(seventh)] true ; 5];
match 0 {
#![print_target_and_args(eighth)]
_ => {}
}
MyStruct { #![print_target_and_args(ninth)] field: true };
}
```
They are
- useless
- unstable (modulo holes like https://github.com/rust-lang/rust/issues/65860)
- pessimize compiler performance, namely token collection for macros (cc https://github.com/rust-lang/rust/pull/82608)
I still want to run crater on this to check whether the stability holes are exploited in practice, and whether such attributes are used at all.
Replace 'NULL' with 'null'
This replaces occurrences of "NULL" with "null" in docs, comments, and compiler error/lint messages. This is for the sake of consistency, as the lowercase "null" is already the dominant form in Rust. The all-caps NULL looks like the C macro (or SQL keyword), which seems out of place in a Rust context, given that NULL does not exist in the Rust language or standard library (instead having [`ptr::null()`](https://doc.rust-lang.org/stable/std/ptr/fn.null.html)).
