2020-02-03Optimize core::ptr::align_offsetAmos Onn-2/+1
- As explained in the comment inside mod_inv, it is valid to work mod `usize::max_value()` right until the end.
2020-02-03Optimize core::ptr::align_offsetAmos Onn-13/+20
- When calculating the inverse, it's enough to work `mod a/g` instead of `mod a`.
2020-02-03Optimize core::ptr::align_offsetAmos Onn-2/+2
- Stopping condition inside mod_inv can be >= instead of > - Remove intrinsics::unchecked_rem, we are working modulu powers-of-2 so we can simply mask
2020-01-28Auto merge of #68234 - CAD97:slice-from-raw-parts, r=KodrAusbors-6/+5
Stabilize ptr::slice_from_raw_parts[_mut] Closes #36925, the tracking issue. Initial impl: #60667 r? @rust-lang/libs In addition to stabilizing, I've adjusted the example of `ptr::slice_from_raw_parts` to use `slice_from_raw_parts` instead of `slice_from_raw_parts_mut`, which was unnecessary for the example as written.

2020-01-09doc: add Null-unchecked version section to mut pointer as_mut methodTrevor Spiteri-0/+14
The as_ref method already has a Null-unchecked version section, its example is a modification of the example in the main as_ref section. Similarly the example in this commit is a modification of the example in main as_mut section.

2019-12-22Rollup merge of #67480 - rossmacarthur:fix-41260-avoid-issue-0-part-2, r=CentrilMazdak Farrokhzad-17/+17
Require issue = "none" over issue = "0" in unstable attributes These changes make the use of `issue = "none"` required in unstable attributes throughout the compiler. Notes: - #66299 is now in beta so `issue = "none"` is accepted. - The `tidy` tool now fails on `issue = "0"`. - Tests that used `issue = "0"` were changed to use `issue = "none"`, except for _one_ that asserts `issue = "0"` can still be used. - The compiler still allows `issue = "0"` because some submodules require it, this could be disallowed once these are updated.

2019-12-21Rollup merge of #67462 - DutchGhost:const_slice_from_raw_parts, r=dtolnayMazdak Farrokhzad-2/+4
Make ptr::slice_from_raw_parts a const fn available under a feature flag A first step in the direction of https://github.com/rust-lang/rust/issues/67456 . This makes `ptr::slice_from_raw_parts` and `ptr::slice_from_raw_parts_mut` available as a const fn under a feature flag.

2019-11-26Format libcore with rustfmtDavid Tolnay-30/+23
This commit applies rustfmt with default settings to files in src/libcore *that are not involved in any currently open PR* to minimize merge conflicts. The list of files involved in open PRs was determined by querying GitHub's GraphQL API with this script: https://gist.github.com/dtolnay/aa9c34993dc051a4f344d1b10e4487e8 With the list of files from the script in `outstanding_files`, the relevant commands were: $ find src/libcore -name '*.rs' | xargs rustfmt --edition=2018 $ rg libcore outstanding_files | xargs git checkout -- Repeating this process several months apart should get us coverage of most of the rest of libcore.

Have tidy ensure that we document all `unsafe` blocks in libcore cc @rust-lang/libs I documented a few and added ignore flags on the other files. We can incrementally document the files, but won't regress any files this way.

2019-07-30Rollup merge of #61965 - phil-opp:patch-4, r=scottmcmMazdak Farrokhzad-2/+2
Remove mentions of removed `offset_to` method from `align_offset` docs The `offset_to` method was deleted in https://github.com/rust-lang/rust/pull/52814. The replacement for the removed method is `wrapping_offset_from`. However, neither method takes an `usize` as argument, so I don't think that it makes sense to mention them.

2019-07-17Refer to `add` method instead of `offset`Philipp Oppermann-2/+2
The `align_offset` method returns an `usize`, so using `add` makes more sense than using `offset`, which takes an `isize`.
