2016-08-13Add some tests for ! typeAndrew Cann-0/+60
2016-08-13Add run-pass/never_coercions.rs testAndrew Cann-0/+19
2016-08-13Rename empty/bang to neverAndrew Cann-3/+1
Split Ty::is_empty method into is_never and is_uninhabited
2016-08-13Control usage of `!` through a feature gate.Andrew Cann-0/+1
Adds the `bang_type` feature gate. `!` in a non-return-type position now relies on that feature.
2016-08-13Remove invalid compile-fail tests related to `!`Andrew Cann-178/+0
These tests check for the old error messages "`return` in a function declared as diverging" and "computation may converge in a function declared as diverging". The first of these is now invalid as `return` is permitted in functions that return `!`. The second of these is subsumed by the "mismatched types" error.
2016-08-13Remove obsolete divergence related stuffAndrew Cann-16/+0
Replace FnOutput with Ty Replace FnConverging(ty) with ty Purge FnDiverging, FunctionRetTy::NoReturn and FunctionRetTy::None

[MIR] Add explicit SetDiscriminant StatementKind for deaggregating enums cc #35186 To deaggregate enums, we need to be able to explicitly set the discriminant. This PR implements a new StatementKind that does that. I think some of the places that have `panics!` now could maybe do something smarter.

2016-08-11Rollup merge of #35576 - circuitfox:E0072-update-error-format, r=jonathandturnerJonathan Turner-0/+5
E0072 update error format Part of #35233 Fixes #35506 r? @jonathandturner The bonus for this issue currently seems to be impossible to do reliably, as the compiler seems to lack span information for item names alone, like `Foo` in `struct Foo { ... }`. It would be possible to hack something together by computing span offsets, but that seems like a solution that would be begging for trouble. A proper solution to this would, of course, be to add span information to the right place (seems to be `rustc::hir::Item::name` but I may be wrong).

r=jonathandturner Turn on new errors and json mode This PR is a big-switch, but on a well-worn path: * Turns on new errors by default (and removes old skool) * Moves json output from behind a flag The RFC for new errors [landed](https://github.com/rust-lang/rfcs/pull/1644) and as part of that we wanted some bake time. It's now had a few weeks + all the time leading up to the RFC of people banging on it. We've also had [editors updating to the new format](https://github.com/saviorisdead/RustyCode/pull/159) and expect more to follow. We also have an [issue on old skool](https://github.com/rust-lang/rust/issues/35330) that needs to be fixed as more errors are switched to the new style, but it seems silly to fix old skool errors when we fully intend to throw the switch in the near future. This makes it lean towards "why not just throw the switch now, rather than waiting a couple more weeks?" I only know of vim that wanted to try to parse the new format but were not sure how, and I think we can reach out to them and work out something in the 8 weeks before this would appear in a stable release. We've [hashed out](https://github.com/rust-lang/rust/issues/35330) stabilizing JSON output, and it seems like people are relatively happy making what we have v1 and then likely adding to it in the future. The idea is that we'd maintain backward compatibility and just add new fields as needed. We'll also work on a separate output format that'd be better suited for interactive tools like IDES (since JSON message can get a little long depending on the error). This PR stabilizes JSON mode, allowing its use without `-Z unstable-options` Combined, this gives editors two ways to support errors going forward: parsing the new error format or using the JSON mode. By moving JSON to stable, we can also add support to Cargo, which plugin authors tell us does help simplify their support story. r? @nikomatsakis cc @rust-lang/tools Closes https://github.com/rust-lang/rust/issues/34826
