I noticed that the `deriving` keyword is deprecated and that `derive` is the replacement. This updates the reference (and other docs) to remove the use `deriving`.
By returning the passed value black_box can be used on data being
passed to a function being benchmarked. This ensures the compiler
does not optimize the function for the input which could result in
the entire function being optimized away.
Currently, we build a closure that does nothing but pass its argument
through to another function, this is rather wasteful and creates lots of
unnecessary closures.
In #20732, that all links in some modules point to the same code
examples was reported. The ID's generated for documents in
librustdoc are not all unique, which means the code rendered as
text is not being properly selected.
This change makes the link to the code section that is next to
the current link.
Originally, this was going to be discussed and revisted, however I've been working on this for months, and a rebase on top of master was about 1 flight's worth of work so I just went ahead and did it.
This gets you as far as being able to target powerpc with, eg:
LD_LIBRARY_PATH=./x86_64-unknown-linux-gnu/stage2/lib/ x86_64-unknown-linux-gnu/stage2/bin/rustc -C linker=powerpc-linux-gnu-gcc --target powerpc-unknown-linux-gnu hello.rs
Would really love to get this out before 1.0. r? @alexcrichton
This should fix both #20020 and #20107. This moves out the code into its own file.
I have a couple concerns that can either be addressed in this PR or in a future one.
- The error reporting for the fulfillment context should be span aware because currently it is attached to the top
of the file which is less then desirable.
- There is a failure in the test file: run-pass/issue-2611-3.rs, this seems like it should be a failure to me, but I am not sure.
As a nit I'm not enthused about the file name, and am open to better suggestions.

Refactor compare_impl_method into its own file. Modify the
code to stop comparing individual parameter bounds.
Instead we now use the predicates list attached to the trait
and implementation generics. This ensures consistency even
when bounds are declared in different places (i.e on
a parameter vs. in a where clause).
Really small correction.
This anti-example in the Closures section is supposed to fail because of a borrow, but it was failing at the type inference because of insufficient type information.
This makes it fail for the expected reason.
No in-tree users. Ugly interface. Closes#14332.
I just happened to notice that this module still lives and has no users. Assuming we don't want it.
