resolve: Fix false-positives from lint `absolute_paths_not_starting_with_crate`
Fixes https://github.com/rust-lang/rust/issues/56311 (stable-to-beta regression)

rustdoc: add bottom margin spacing to nested lists
the current CSS for nested lists sets margin-bottom to zero, which means that a nested list is squished up against subsequent list items/paragraphs
this changes the bottom margin to .6em, same as for paragraphs

fix futures creating aliasing mutable and shared ref
Fixes the problem described in https://github.com/solson/miri/issues/532#issuecomment-442552764: `set_task_waker` takes a shared reference and puts a copy into the TLS (in a `NonNull`), but `get_task_waker` gets it back out as a mutable reference. That violates "mutable references must not alias anything"!

rustc-guide has moved to rust-lang/

Update outdated code comments in StringReader
For the detection of newlines in the lexer, this is now done in `analyze_source_file.rs`.
|
|
Remove unsafe `unsafe` inner function.
Within this `Iterator` implementation, a function `unsafe_get` is
defined which unsafely allows _unchecked_ indexing of any element in a
slice. This should be marked as _unsafe_, but it is not.
To address this issue, I removed that inner function.

Suggest appropriate place for lifetime when declared after type arguments

Make std::os::unix/linux::fs::MetadataExt::a/m/ctime* documentation clearer
I was confused by this API so I clarified what they are doing.
I was wondering if I should try to unify more documentation and examples between `unix` and `linux` (e.g. “of the file” is used in `unix` to refer to the file these metadata is for, “of this file” in `linux`, “of the underlying file” in `std::fs::File`).

Add rustc-guide as a submodule
Adding this as a submodule will allow two things:
- Linking to the guide from doc.rlo
- Doing a link check as part of the rust CI build
Key question: Do we want to wait for the book to be filled out more? e.g. do we ever want to move it out of the nursery?

Fix small doc mistake on std::io::read::read_to_end
The std::io::read main documentation can lead to error because the buffer is prefilled with 10 zeros that will pad the response.
Using an empty vector is better.
The `read_to_end` documentation is already correct though.
This is my first rust PR, don't hesitate to tell me if I did something wrong.
|
|
Enclose type in backticks for "non-exhaustive patterns" error
This makes the error style consistent with the convention in error messages.
|
|
Reduce the amount of bold text at doc.rlo
Currently, all of the text is either huge or small. IMHO this is hard to read, so I propose that we make the second-level headings smaller, without making them any less prominent.

atomic::Ordering: Get rid of misleading parts of intro
Remove the parts of atomic::Ordering's intro that wrongly claimed that
SeqCst prevents all reorderings around it.
Closes #55196
This is a (minimal) alternative to #55233.
I also wonder if it would be worth adding at least some warnings that atomics are often a footgun/hard to use correctly, similarly like `mem::transmute` or other functions have.

avoid features_untracked
The docs say to not use `features_untracked` when we have a tcx.
@oli-obk any particular reason why the untracked version is used all over const qualification?

bootstrap: clean up a few clippy findings
remove useless format!()s
remove redundant field names in a few struct initializations
pass slice instead of a vector to a function
use is_empty() instead of comparisons to .len()
No functional change intended.

rustc_codegen_llvm: don't overalign loads of pair operands.
Counterpart to #56300, but for loads instead of stores.

Fix alignment of stores to scalar pair
The alignment for the second element of a scalar pair is not the same as for the first element, make sure it is calculated correctly. This fixes #56267.

set to zero meant that the nested list was squished up against
subsequent list items/paragraphs
this changes the bottom margin to .6em, same as for paragraphs
an example demonstrating the difference with screenshots is given in the
pull request

In particular to pull in a fix for #56265.

The alignment for the second element of a scalar pair is not the
same as for the first element. Make sure it is computed correctly
based on the element size.
