Const-stabilize `const_int_ops` + `const_ip` r? @oli-obk ## Note for relnotes: This PR includes https://github.com/rust-lang/rust/pull/57105. I've added T-lang since this affects intrinsics and the operational semantics of Rust's `const fn` fragment. ## Stable APIs proposed for constification + `const_int_ops`: + `count_ones` + `count_zeros` + `leading_zeros` + `trailing_zeros` + `swap_bytes` + `from_be` + `from_le` + `to_be` + `to_le` + `const_ip` + `Ipv4Addr::new` ## Unstable APIs constified + `const_int_conversion`: + `reverse_bits`

2019-01-07Rollup merge of #57358 - euclio:docck-unicode, r=QuietMisdreavusPietro Albini-1/+1
use utf-8 throughout htmldocck This commit improves compatibility with Python 3, which already uses Unicode throughout. It also fixes a subtle incompatibility stemming from the use of `entitydefs`, which contains replacement text _encoded in latin-1_ for HTML entities. When using Python 3, this would cause `0xa0` to be incorrectly added to the element tree. This meant that there was a rustdoc test that would pass under Python 2 but fail under Python 3, due to an incorrect regex match against the non-breaking space character. This commit triggers that failure in both versions, and also fixes it.

NLL: Fix bug in associated constant type annotations. Fixes #57280. This PR reverses the variance used when relating types from the type annotation of an associated constant - this matches the behaviour of the lexical borrow checker and fixes a bug whereby matching a `&'a str` against a `&'static str` would produce an error. r? @nikomatsakis

tests: Do not use `-Z parse-only`, continue compilation to test recovery Make tests closer to reality! The next step will be enabling `-Z continue-parse-after-error` by default and looking at the regressions. A few instances of `-Z parse-only` are kept when it's appropriate, see e.g `ui/impl-trait/impl-trait-plus-priority.rs`, which tests mostly semantically wrong code and would generate too much useless noise if allowed to continue.

2019-01-06Auto merge of #57291 - euclio:method-call-suggestion, r=estebankbors-33/+33
use structured suggestion for method calls Furthermore, don't suggest calling the method if it is part of a place expression, as this is invalid syntax. I'm thinking it might be worth putting a label on the method assignment span like "this is a method" and removing the span from the "methods are immutable" text so it isn't reported twice. The suggestions in `src/test/ui/did_you_mean/issue-40396.stderr` are suboptimal. I could check if the containing expression is `BinOp`, but I'm not sure if that's general enough. Any ideas? r? @estebank

bootstrap: Link LLVM as a dylib with ThinLTO (take 2) When building a distributed compiler on Linux where we use ThinLTO to create the LLVM shared object this commit switches the compiler to dynamically linking that LLVM artifact instead of statically linking to LLVM. The primary goal here is to reduce CI compile times, avoiding two+ ThinLTO builds of all of LLVM. By linking dynamically to LLVM we'll reuse the one ThinLTO step done by LLVM's build itself. Lots of discussion about this change can be found [here] and down. A perf run will show whether this is worth it or not! [here]: https://github.com/rust-lang/rust/pull/53245#issuecomment-417015334 --- This PR previously landed in https://github.com/rust-lang/rust/pull/56944, caused https://github.com/rust-lang/rust/issues/57111, and was reverted in https://github.com/rust-lang/rust/pull/57116. I've added one more commit here which should fix the breakage that we saw.

2019-01-05Rollup merge of #57338 - QuietMisdreavus:doctest-file-name, r=GuillaumeGomezkennytm-0/+7
rustdoc: force binary filename for compiled doctests Fixes https://github.com/rust-lang/rust/issues/57317, needed for https://github.com/rust-lang/rust-by-example/issues/1137 Right now, when building a doctest, rustdoc provides the compiler an output directory (a temp dir) but lets the compiler name the executable. If the doctest needs to be executed, it then tries to run a binary named `rust_out` from that directory. For the most part, this works fine. However, if the doctest sets its own crate name, the compiler uses that name for the output binary instead. This causes rustdoc to try to execute a nonexistent binary, causing the test to fail. This PR changes the paths rustdoc gives to the compiler when building doctests to force the output *filename* instead of just the *directory*.

2019-01-05Rollup merge of #57233 - Smibu:rename-and-fix-nolink-test, r=alexcrichtonkennytm-13/+12
Rename and fix nolink-with-link-args test There are three problems with the nolink-with-link-args test: * The test fails when using MSVC. It's caused by the `linker-flavor=ld` flag which was added in #46291. * In its comment, this test tests that "link_args are indeed passed when nolink is specified", but the `nolink` attribute has been removed [a long time ago](https://github.com/rust-lang/rust/pull/12826). * Pattern has a small typo. At first I was going to completely remove this test, but there is [a closed pull request for that](https://github.com/rust-lang/rust/pull/21090). So: * rename the file as suggested in the closed PR * adjust the comment * fix typo in the pattern * add `ignore-msvc`. r? @alexcrichton
