This takes the time for `rustc libstd/lib.rs -Z ast-json-noexpand >
file.json` from 9.0s to 3.5s (~0.5s spent parsing etc.) and `-Z
ast-json` from 11s to 5s (~1.5s spent parsing and expanding).
This is adequate because when a function has a type that isn't caught here,
that is, it has a single argument, but it *isn't* `&mut BenchHarness`, it
errors later on with:
error: mismatched types: expected `fn(&mut test::BenchHarness)` but found
`fn(int)` (expected &-ptr but found int)
which I consider acceptable.
Closes#12997
This adds lots of docs to the atomics module. Two of the examples
are using the future atomics API and are ignored temporarily.
I discovered a bug in the way AtomicBool's fetch_nand method is
implemented and fixed it by using the correct value for `true`.
I also fixed the implementation of AcqRel fences (it was only doing
a release barrier), and made a "relaxed" fence a failure.
This PR enables the use of mutable slices in *mutable* static items. The work was started by @xales and I added a follow-up commit that moves the *immutable* restriction to the recently added `check_static`
Closes#11411
its a common (yet easily fixable) error to just forget parens at the end of getter-like methods without any arguments.
The current error message for that case asks for an anonymous function, this patch adds a note asking for either an anonymous function, or for trailing parens.
This is my first contribution! do i need to do anything else?
The same test was missed in chan/port renaming PR #12815 and was fixed in #12880:
> This was missed because it is skipped on linux and windows, and the mac bots were moving at the time the PR landed.
It seems the same happened to the liblog PR.
This is a minor optimization of the bignum module. The improvements mostly come from avoiding allocations and boundary checks. This also switches all of libnum to vec_ng::Vec.
This will enable rustdoc to treat them specially.
I also got rid of `std::cmp::cmp2`, which is isomorphic to the `TotalOrd` impl for 2-tuples and never used.
