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.
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.
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.
r? @eddyb
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.

Upgrade LLVM to trunk, still version 8
This commit upgrades the LLVM/LLD/compiler-rt submodules used to the current trunk versions in upstream. Some activity has happened on the wasm SIMD side of things as well as LLD which we'd like to pick up!
Make `ParseIntError` and `IntErrorKind` fully public
Why would you write nice error types if I can't read them?
# Why
It can be useful to use `match` with errors produced when parsing strings to int. This would be useful for the `.err_match()` function in my [new crate](https://crates.io/crates/read_input).
---
I could also do this for `ParseFloatError` if people think it is a good idea.
I am new around hear so please tell me if I am getting anything wrong.
Try to make top-level Cargo.toml work without __CARGO_TEST_ROOT.
The last failures I noticed before adding the `__CARGO_TEST_ROOT` hack were in `src/test/run-make/thumb-none-{cortex-m,qemu}`, and had to do with the fact that the top-level `Cargo.toml` uses nightly Cargo features.
If that's the only problem, this PR should work, and we can figure out how to unbreak RLS.
