2019-01-22Fix some cross crate existential type ICEsOliver Scherer-2/+68
2019-01-22unit test for issue 57673.Felix S. Klock II-0/+21
2019-01-22Do not initiate nested probe within `assemble_probe`.Felix S. Klock II-9/+7
In particular, the table entries (associated with type-variables created during the probe) must persist as long as the candidates assembled during the probe. If you make a nested probe without creating a nested `ProbeContext`, the table entries are popped at the end of the nested probe, while the type-variables would leak out via the assembled candidates attached to `self` (the outer `ProbeContext`). This causes an ICE (*if you are lucky*)!

2019-01-22Rollup merge of #57677 - dotdash:locals, r=michaelwoeristerMazdak Farrokhzad-18/+24
const_eval: Predetermine the layout of all locals when pushing a stack frame Usually the layout of any locals is required at least three times, once when it becomes live, once when it is written to, and once it is read from. By adding a cache for them, we can reduce the number of layout queries speeding up code that is heavy on const_eval.

2019-01-22Auto merge of #56221 - estebank:remove-dummy-checks, r=varkorbors-18/+24
Remove unnecessary dummy span checks The emitter already verifies wether a given span note or span label can be emitted to the output. If it can't, because it is a dummy span, it will be either elided for labels or emitted as an unspanned note/help when applicable.

2019-01-22Extend trailing `>` detection for paths.David Wood-33/+131
This commit extends the trailing `>` detection to also work for paths such as `Foo::<Bar>>:Baz`. This involves making the existing check take the token that is expected to follow the path being checked as a parameter. Care is taken to ensure that this only happens on the construction of a whole path segment and not a partial path segment (during recursion). Through this enhancement, it was also observed that the ordering of right shift token and greater than tokens was overfitted to the examples being tested. In practice, given a sequence of `>` characters: `>>>>>>>>>` ..then they will be split into `>>` eagerly: `>> >> >> >> >`. ..but when a `<` is prepended, then the first `>>` is split: `<T> > >> >> >> >` ..and then when another `<` is prepended, a right shift is first again: `Vec<<T>> >> >> >> >` In the previous commits, a example that had two `<<` characters was always used and therefore it was incorrectly assumed that `>>` would always be first - but when there is a single `<`, this is not the case.

2019-01-21Speed up the fast path for assert_eq! and assert_ne!Björn Steinbrink-4/+16
Currently, the panic!() calls directly borrow the value bindings. This causes those bindings to always be initialized, i.e. they're initialized even before the values are even compared. This causes noticeable overhead in what should be a really cheap operation. By performing a reborrow of the value in the call to panic!(), we allow LLVM to optimize that code, so that the extra borrow only happens in the error case. We could achieve the same result by dereferencing the values passed to panic!(), as the format machinery borrows them anyway, but this causes assertions to fail to compile if one of the values is unsized, i.e. it would be a breaking change.

2019-01-21Fix some non-determinism in help messages for E0277 errors.Simon Sapin-7/+11
The diagnostic for this error prints `the following implementations were found` followed by the first N relevant impls, sorted. This commit makes the sort happen before slicing, so that the set of impls being printed is deterministic when the input is not.

r=Mark-Simulacrum Install missing 'rust-gdbui'' PR #53774 added `rust-gdbui` as wrapper to launch [gdbui](https://gdbgui.com/), similar to `rust-gdb`. Unfortunately I've never seen the script in my local installation (from rustup, using rust 1.31.1). @tromey on the PR [suggested it might be missing](https://github.com/rust-lang/rust/pull/53774#issuecomment-419704939) from the installation process. This PR simply adds a line for `rust-gdbui` too.
