This is a really minor issue. I noticed some tests no longer need the ignore
tidy comment directive.
A quick grep turned up the following files:
src/test/compile-fail/bad-mid-path-type-params.rs
src/test/compile-fail/bad-sized.rs
src/test/compile-fail/coherence-default-trait-impl.rs
src/test/compile-fail/coherence-orphan.rs
src/test/compile-fail/issue-8767.rs
src/test/compile-fail/lint-stability.rs
src/test/compile-fail/lint-uppercase-variables.rs
src/test/compile-fail/typeck-default-trait-impl-outside-crate.rs
src/test/compile-fail/use-after-move-implicity-coerced-object.rs
src/test/debuginfo/gdb-pretty-std.rs
It didn't seem like it was worth opening an issue for this, but if that is not
the case (i.e. it is required), I'll open one up. Thanks!
This commit stabilizes the old `io::Error::from_os_error` after being renamed to
use the `raw_os_error` terminology instead. This function is often useful when
writing bindings to OS functions but only actually converting to an I/O error at
a later point.
This method hasn't really changed since is inception, and it can often be a
nice performance win for some situations. This method also imposes no burden on
implementors or users of `Clone` as it's just a default method on the side.
Now that we have a `#[allow_internal_unstable]` attribute for macros there's no
need for these two `begin_unwind` functions to be stable. Right now the `panic!`
interface is the only one we wish to stabilize, so remove the stability markers
from these functions.
While this is a breaking change, it is highly unlikely to break any actual code.
It is recommended to use the `panic!` macro instead if it breaks explicit calls
into `std::rt`.

I'm using this to integrate rustc with [american-fuzzy-lop](http://lcamtuf.coredump.cx/afl/). Building with afl instrumentation is no different from loading any other plugin library.
I'd like this PR to include a `run-make` test with a custom LLVM pass; however I'm not sure it's worth the trouble of building C++ code and linking LLVM from the test suite (are there existing tests that do this?)
Modify the ExprUseVisitor to walk each part of an AutoRef, and in
particular to treat an AutoUnsize as as kind of \"instantaneous\" borrow
of the value being unsized. This prevents us from feeding uninitialized
data.
This caused a problem for the eager reborrow of comparison traits,
because that wound up introducing a \"double AutoRef\", which was not
being thoroughly checked before but turned out not to type check.
Fortunately, we can just remove that \"eager reborrow\" as it is no longer
needed now that `PartialEq` doesn't force both LHS and RHS to have the
same type (and even if we did have this problem, the better way would be
to lean on introducing a common supertype).
Fixes#20791.

This commit changes `Iterator`'s API by:
* Generalizing bounds from `Iterator` to `IntoIterator` whenever
possible, matching the semantics and ergonomics of `for` loops.
* Tightens up a few method-level bounds so that you get an error
earlier. For example, `rev` did not require `DoubleEndedIterator` even
though the result is only an `Iterator` when the original iterator was
double-ended.
Closes#23587
The bound-tightening is technically a:

but no code should break in practice.
The idea here is if you don't want rust in /usr/local
you can put something like this is your .profile:
```
export RUSTUP_PREFIX=$HOME/.local/rust
export PATH=$PATH:${RUSTUP_PREFIX}/bin
export DYLD_LIBRARY_PATH=$DYLD_LIBRARY_PATH:${RUSTUP_PREFIX}/lib
```
Then when you run rustup, it will update the install
in ${RUSTUP_PREFIX} without having to remember to pass
an explicit --prefix argument every time.

We only implemented Clone on `extern "Rust" fn`s (for up to 8
parameters). This didn't cover `extern "C"` or `unsafe` (or
`unsafe extern "C"`) `fn`s, but there's no reason why they shouldn't be
cloneable as well.
The new impls are marked unstable because the existing impl for `extern
"Rust" fn`s is.
Fixes#24161.
