- using libgreen to optimize CPU usage
- less tasks to limit wasted resources
Here, on a one core 2 threads CPU, new version is ~1.2 faster. May
be better with more core.
This was removed because these could alias with `&const T` or `@mut T`
and those are now gone from the language. There are still aliasing
issues within local scopes, but this is correct for function parameters.
This also removes the no-op `noalias` marker on proc (not a pointer) and
leaves out the mention of #6750 because real type-based alias analysis
is not within the scope of best effort usage of the `noalias` attribute.
Test case:
pub fn foo(x: &mut &mut u32) {
**x = 5;
**x = 5;
}
Before:
define void @_ZN3foo20h0ce94c9671b0150bdaa4v0.0E(i32** nocapture readonly) unnamed_addr #0 {
entry-block:
%1 = load i32** %0, align 8
store i32 5, i32* %1, align 4
%2 = load i32** %0, align 8
store i32 5, i32* %2, align 4
ret void
}
After:
define void @_ZN3foo20h0ce94c9671b0150bdaa4v0.0E(i32** noalias nocapture readonly) unnamed_addr #0 {
entry-block:
%1 = load i32** %0, align 8
store i32 5, i32* %1, align 4
ret void
}

The years of copyright and the name of the copyright holder were not
present in the notice.
The Apache license was added to the project in 2012, so 2012 is the
starting year. The copyright holder is the Mozilla Foundation (taken
from the MIT license).
This commit removes the inherited documentation from type pages. This generally
just clutters up the page when you can click through to the trait itself to get
all the meaty documentation.
Closes#11991
This primary fix brought on by this upgrade is the proper matching of the ```
and ~~~ doc blocks. This also moves hoedown to a git submodule rather than a
bundled repository.
Additionally, hoedown is stricter about code blocks, so this ended up fixing a
lot of invalid code blocks (ending with " ```" instead of "```", or ending with
"~~~~" instead of "~~~").
Closes#12776
This ensures that private functions exported through static initializers will
actually end up being public in the object file (so other objects can continue
to reference the function).

Closes#7575.
I don't think the change from a contains lookup to an iteration of the HashSet in the resolver should be much of a burden as the set of methods with the same name should be relatively small.
This is a first patch towards an opt-in built-in trait world. This patch removes the restriction on built-in traits and allows such traits to be derived.

This allows writing code examples which pass all analysis of the compiler, but
don't actually link. A good example is examples that use extern {} blocks.
Closes#12903
Rustdoc currently doesn't inline documentation of a `pub use` if the target is
publicly reachable. This changes rustdoc to allow a #[doc(inline)] attribute to
force inlining the documentation, regardless of whether the targe is public or
not.
Closes#13045
The outer attributes were manually appended when a module file was parsed, but
the attributes were also added higher up the stack of parsing (when the module
finished parsing). This removes the append in parsing the module file.
Closes#13826
These fonts were moved into place by rust's makefiles, but rustdoc is widely
used outside of rustc itself. This moves the fonts into the rustdoc binary,
similarly to the other static assets, and writes them to the output location
whenever rustdoc generates documentation.

This change allow a speedup of ~1.5 on shootout-pidigits on a i32
system. `MachineUint` is used to abstract the internal machine
unsigned integer to simplity future architecture specialization.
