adjust range tests Since the desugaring removed special handling for ranges, the error message changed and so I had to adjust `range-1`. Turns out there was a bug where borrowck was too restrictive in some rare cases of constructing ranges from literals. The `range-2` test enshrined this bug -- now it's adjusted to test a case that's actually wrong. 2016-01-13 06:29:39 +00:00			`//~^ ERROR mismatched types`

Stabilize std::num This commit stabilizes the `std::num` module: * The `Int` and `Float` traits are deprecated in favor of (1) the newly-added inherent methods and (2) the generic traits available in rust-lang/num. * The `Zero` and `One` traits are reintroduced in `std::num`, which together with various other traits allow you to recover the most common forms of generic programming. * The `FromStrRadix` trait, and associated free function, is deprecated in favor of inherent implementations. * A wide range of methods and constants for both integers and floating point numbers are now `#[stable]`, having been adjusted for integer guidelines. * `is_positive` and `is_negative` are renamed to `is_sign_positive` and `is_sign_negative`, in order to address #22985 * The `Wrapping` type is moved to `std::num` and stabilized; `WrappingOps` is deprecated in favor of inherent methods on the integer types, and direct implementation of operations on `Wrapping<X>` for each concrete integer type `X`.

pretty: trim paths of unique symbols If a symbol name can only be imported from one place for a type, and as long as it was not glob-imported anywhere in the current crate, we can trim its printed path and print only the name. This has wide implications on error messages with types, for example, shortening `std::vec::Vec` to just `Vec`, as long as there is no other `Vec` importable anywhere. This adds a new '-Z trim-diagnostic-paths=false' option to control this feature. On the good path, with no diagnosis printed, we should try to avoid issuing this query, so we need to prevent trimmed_def_paths query on several cases. This change also relies on a previous commit that differentiates between `Debug` and `Display` on various rustc types, where the latter is trimmed and presented to the user and the former is not. 2020-09-02 07:40:56 +00:00			//~^ ERROR `bool: Step` is not satisfied
