2019-07-02HashMap is UnwindSafeSimon Sapin-0/+12
Fixes https://github.com/rust-lang/rust/issues/62301, a regression in 1.36.0 which was caused by hashbrown using `NonZero<T>` where the older hashmap used `Unique<T>`.

2019-06-26Beta backport of: Auto merge of #61754 - nikomatsakis:trait-caching-perf-3, ↵Niko Matsakis-83/+407
r=pnkfelix create a "provisional cache" to restore performance in the case of cycles Introduce a "provisional cache" that caches the results of auto trait resolutions but keeps them from entering the *main* cache until everything is ready. This turned out a bit more complex than I hoped, but I don't see another short term fix -- happy to take suggestions! In the meantime, it's very clear we need to rework the trait solver. This resolves the extreme performance slowdown experienced in #60846 -- I plan to add a perf.rust-lang.org regression test to track this. Caveat: I've not run `x.py test` in full yet. r? @pnkfelix cc @arielb1 Fixes #60846
2019-06-26Revert "Set test flag when rustdoc is running with --test option"Oliver Middleton-12/+12
This reverts commit 8ed2292dbe75b9b65e9fe1a079428d1e1e3b610f. It caused doctests in this repository to no longer be tested including all of the core crate.

2019-05-28debuginfo: Revert to old/more verbose behavior for -Cdebuginfo=1.Michael Woerister-2/+21
https://github.com/rust-lang/rust/commit/cff075009 made LLVM emit less debuginfo when compiling with "line-tables-only". The change was essentially correct but the reduced amount of debuginfo broke a number of tools. This commit reverts the change so we get back the old behavior, until we figure out how to do this properly and give external tools to adapt to the new format. See https://github.com/rust-lang/rust/issues/60020 for more info.

2019-05-21Auto merge of #60985 - cr1901:msp430-fix, r=alexcrichtonbors-0/+0
Bump LLVM submodule to fix MSP430 AsmPrinter and assembler syntax mismatch. Moving on to steps 9 and 10 of the llvm bugfix [guide](https://rust-lang.github.io/rustc-guide/codegen/updating-llvm.html#bugfix-updates), now that Rust's copy of LLVM was [updated](https://github.com/rust-lang/llvm-project/pull/13). This PR closes issue #59077. Nightlies following this PR should have working msp430 codegen again :D. Thanks for the prompt response even though it took me a while to get this "simple" PR done!
2019-05-20Rollup merge of #60983 - petrhosek:libunwind-no-exceptions, r=alexcrichtonMazdak Farrokhzad-5/+2
Set -funwind-tables and -fno-exceptions unconditionally for LLVM's libunwind These are required otherwise libunwind will end up with undefined references to __gxx_personality_v0 which is provided by C++ ABI library and that's undesirable.
2019-05-20Rollup merge of #60972 - RalfJung:volatile, r=alexcrichtonMazdak Farrokhzad-6/+0
remove confusing remarks about mixed volatile and non-volatile accesses These comments were originally added by @ecstatic-morse in https://github.com/rust-lang/rust/commit/911d35f0bfd207112806eaec2763201dad06d1c7 and then later edited by me. The intention, I think, was to make sure people do both their reads and writes with these methods if the affected memory really is used for communication with external devices. However, [people read this as saying that mixed volatile/non-volatile accesses are UB](https://github.com/rust-lang/rust/issues/58599#issuecomment-493791130), which -- to my knowledge -- they are not. So better remove this. Cc @rkruppe @rust-lang/wg-unsafe-code-guidelines

Document BinaryHeap time complexity I went into some detail on the time complexity of `push` because it is relevant for using BinaryHeap efficiently -- specifically that you should avoid pushing many elements in ascending order when possible. r? @Amanieu Closes #47976. Closes #59698.

2019-05-20Rollup merge of #60915 - michaelwoerister:hashstablestuff, r=estebankMazdak Farrokhzad-20/+24
stable hashing: Remove unused field and add documentation. This PR removes the `bytes_hashed` field from `StableHasher` which in the past has been used for collecting some statistics but has gone unused for quite a while (months at least) now. The PR also tries to document some requirements for `HashStable` implementations that haven't been written down explicitly anywhere.
