2015-03-26Switch drop-flag to `u8` to allow special tags to instrument state.Felix S. Klock II-3/+3
Refactored code so that the drop-flag values for initialized (`DTOR_NEEDED`) versus dropped (`DTOR_DONE`) are given explicit names. Add `mem::dropped()` (which with `DTOR_DONE == 0` is semantically the same as `mem::zeroed`, but the point is that it abstracts away from the particular choice of value for `DTOR_DONE`). Filling-drop needs to use something other than `ptr::read_and_zero`, so I added such a function: `ptr::read_and_drop`. But, libraries should not use it if they can otherwise avoid it. Fixes to tests to accommodate filling-drop.

2015-03-03Add `: Box<_>` or `::Box<_>` type annotations to various places.Felix S. Klock II-1/+2
This is the kind of change that one is expected to need to make to accommodate overloaded-`box`. ---- Note that this is not *all* of the changes necessary to accommodate Issue 22181. It is merely the subset of those cases where there was already a let-binding in place that made it easy to add the necesasry type ascription. (For unnamed intermediate `Box` values, one must go down a different route; `Box::new` is the option that maximizes portability, but has potential inefficiency depending on whether the call is inlined.) ---- There is one place worth note, `run-pass/coerce-match.rs`, where I used an ugly form of `Box<_>` type ascription where I would have preferred to use `Box::new` to accommodate overloaded-`box`. I deliberately did not use `Box::new` here, because that is already done in coerce-match-calls.rs. ---- Precursor for overloaded-`box` and placement-`in`; see Issue 22181.

2015-02-23Use boxed functions instead of transmuteStepan Koltsov-2/+3
... to convert between Box and raw pointers. E. g. use ``` let b: Box<Foo> = Box::from_raw(p); ``` instead of ``` let b: Box<Foo> = mem::transmute(p); ``` Patch also changes closure release code in `src/libstd/sys/unix/thread.rs` when `pthread_create` failed. Raw pointer was transmuted to box of `FnOnce()` instead of `Thunk`. This code was probably never executed, because `pthread_create` rarely fails in practice.

2015-02-18Stabilize std::borrowAaron Turon-7/+0
This commit stabilizes `std::borrow`, making the following modifications to catch up the API with language changes: * It renames `BorrowFrom` to `Borrow`, as was originally intended (but blocked for technical reasons), and reorders the parameters accordingly. * It moves the type parameter of `ToOwned` to an associated type. This is somewhat less flexible, in that each borrowed type must have a unique owned type, but leads to a significant simplification for `Cow`. Flexibility can be regained by using newtyped slices, which is advisable for other reasons anyway. * It removes the owned type parameter from `Cow`, making the type much less verbose. * Deprecates the `is_owned` and `is_borrowed` predicates in favor of direct matching. The above API changes are relatively minor; the basic functionality remains the same, and essentially the whole module is now marked `#[stable]`. [breaking-change]
2015-02-18std: Stabilize the `hash` moduleAlex Crichton-2/+10
This commit is an implementation of [RFC 823][rfc] which is another pass over the `std::hash` module for stabilization. The contents of the module were not entirely marked stable, but some portions which remained quite similar to the previous incarnation are now marked `#[stable]`. Specifically: [rfc]: https://github.com/rust-lang/rfcs/blob/master/text/0823-hash-simplification.md * `std::hash` is now stable (the name) * `Hash` is now stable * `Hash::hash` is now stable * `Hasher` is now stable * `SipHasher` is now stable * `SipHasher::new` and `new_with_keys` are now stable * `Hasher for SipHasher` is now stable * Many `Hash` implementations are now stable All other portions of the `hash` module remain `#[unstable]` as they are less commonly used and were recently redesigned. This commit is a breaking change due to the modifications to the `std::hash` API and more details can be found on the [RFC][rfc]. Closes #22467 [breaking-change]

An "immutable reference-counted pointer" is confusing, one might think that the `Rc` itself is immutable which isn't the case.

Since the snapshot compiler is still using an older LLVM version, omit the call in stage0, because compile times explode otherwise.

2015-01-20std: Rename Show/String to Debug/DisplayAlex Crichton-8/+8
This commit is an implementation of [RFC 565][rfc] which is a stabilization of the `std::fmt` module and the implementations of various formatting traits. Specifically, the following changes were performed: [rfc]: https://github.com/rust-lang/rfcs/blob/master/text/0565-show-string-guidelines.md * The `Show` trait is now deprecated, it was renamed to `Debug` * The `String` trait is now deprecated, it was renamed to `Display` * Many `Debug` and `Display` implementations were audited in accordance with the RFC and audited implementations now have the `#[stable]` attribute * Integers and floats no longer print a suffix * Smart pointers no longer print details that they are a smart pointer * Paths with `Debug` are now quoted and escape characters * The `unwrap` methods on `Result` now require `Display` instead of `Debug` * The `Error` trait no longer has a `detail` method and now requires that `Display` must be implemented. With the loss of `String`, this has moved into libcore. * `impl<E: Error> FromError<E> for Box<Error>` now exists * `derive(Show)` has been renamed to `derive(Debug)`. This is not currently warned about due to warnings being emitted on stage1+ While backwards compatibility is attempted to be maintained with a blanket implementation of `Display` for the old `String` trait (and the same for `Show`/`Debug`) this is still a breaking change due to primitives no longer implementing `String` as well as modifications such as `unwrap` and the `Error` trait. Most code is fairly straightforward to update with a rename or tweaks of method calls. [breaking-change] Closes #21436

2015-01-21Use assume to inform the optimiser about refcount invariantsJames Miller-2/+13
The reference count can never be 0, unless we're about to drop the data completely. Using the `assume` intrinsic allows us to inform LLVM about that invariant, meaning it can avoid unnecessary drops.
