2014-05-17std: Refactor liballoc out of lib{std,sync}Alex Crichton-1/+2
This commit is part of the libstd facade RFC, issue #13851. This creates a new library, liballoc, which is intended to be the core allocation library for all of Rust. It is pinned on the basic assumption that an allocation failure is an abort or failure. This module has inherited the heap/libc_heap modules from std::rt, the owned/rc modules from std, and the arc module from libsync. These three pointers are currently the three most core pointer implementations in Rust. The UnsafeArc type in std::sync should be considered deprecated and replaced by Arc<Unsafe<T>>. This commit does not currently migrate to this type, but future commits will continue this refactoring.
2014-05-11core: Remove the cast moduleAlex Crichton-10/+9
This commit revisits the `cast` module in libcore and libstd, and scrutinizes all functions inside of it. The result was to remove the `cast` module entirely, folding all functionality into the `mem` module. Specifically, this is the fate of each function in the `cast` module. * transmute - This function was moved to `mem`, but it is now marked as #[unstable]. This is due to planned changes to the `transmute` function and how it can be invoked (see the #[unstable] comment). For more information, see RFC 5 and #12898 * transmute_copy - This function was moved to `mem`, with clarification that is is not an error to invoke it with T/U that are different sizes, but rather that it is strongly discouraged. This function is now #[stable] * forget - This function was moved to `mem` and marked #[stable] * bump_box_refcount - This function was removed due to the deprecation of managed boxes as well as its questionable utility. * transmute_mut - This function was previously deprecated, and removed as part of this commit. * transmute_mut_unsafe - This function doesn't serve much of a purpose when it can be achieved with an `as` in safe code, so it was removed. * transmute_lifetime - This function was removed because it is likely a strong indication that code is incorrect in the first place. * transmute_mut_lifetime - This function was removed for the same reasons as `transmute_lifetime` * copy_lifetime - This function was moved to `mem`, but it is marked `#[unstable]` now due to the likelihood of being removed in the future if it is found to not be very useful. * copy_mut_lifetime - This function was also moved to `mem`, but had the same treatment as `copy_lifetime`. * copy_lifetime_vec - This function was removed because it is not used today, and its existence is not necessary with DST (copy_lifetime will suffice). In summary, the cast module was stripped down to these functions, and then the functions were moved to the `mem` module. transmute - #[unstable] transmute_copy - #[stable] forget - #[stable] copy_lifetime - #[unstable] copy_mut_lifetime - #[unstable] [breaking-change]
2014-05-10rename `global_heap` -> `libc_heap`Daniel Micay-4/+3
This module only contains wrappers for malloc and realloc with out-of-memory checks.
2014-05-10initial port of the exchange allocator to jemallocDaniel Micay-2/+3
In stage0, all allocations are 8-byte aligned. Passing a size and alignment to free is not yet implemented everywhere (0 size and 8 align are used as placeholders). Fixing this is part of #13994. Closes #13616

2014-02-23std: Remove unstable::langBrian Anderson-1/+18
Put the lonely lang items here closer to the code they are calling.

Issue #1457

2014-02-14Register new snapshotsAlex Crichton-3/+0
This enables the parser error for `extern mod` => `extern crate` transitions.
2014-02-13Don't allocate in LocalHeap::new()Alex Crichton-7/+8
One of these is allocated for every task, trying to cut down on allocations cc #11389
2014-02-13Register new snapshotsAlex Crichton-74/+0
2014-02-07remove type descriptors from proc and @TDaniel Micay-0/+61
This also drops support for the managed pointer POISON_ON_FREE feature as it's not worth adding back the support for it. After a snapshot, the leftovers can be removed.

2013-10-26Rewrite boxed_region/memory_region in RustAlex Crichton-64/+238
This drops more of the old C++ runtime to rather be written in rust. A few features were lost along the way, but hopefully not too many. The main loss is that there are no longer backtraces associated with allocations (rust doesn't have a way of acquiring those just yet). Other than that though, I believe that the rest of the debugging utilities made their way over into rust. Closes #8704

2013-08-27librustc: Ensure that type parameters are in the right positions in paths.Patrick Walton-3/+4
This removes the stacking of type parameters that occurs when invoking trait methods, and fixes all places in the standard library that were relying on it. It is somewhat awkward in places; I think we'll probably want something like the `Foo::<for T>::new()` syntax.

2013-08-09Remove the C++ runtime. SayonaraBrian Anderson-27/+4
2013-08-09std: Fix perf of local allocations in newschedBrian Anderson-7/+15
Mostly optimizing TLS accesses to bring local heap allocation performance closer to that of oldsched. It's not completely at parity but removing the branches involved in supporting oldsched and optimizing pthread_get/setspecific to instead use our dedicated TCB slot will probably make up for it.
2013-08-02librustc: Disallow "unsafe" for external functionsPatrick Walton-1/+1
2013-07-26Consolidate raw representations of rust valuesAlex Crichton-3/+3
This moves the raw struct layout of closures, vectors, boxes, and strings into a new `unstable::raw` module. This is meant to be a centralized location to find information for the layout of these values. As safe method, `repr`, is provided to convert a rust value to its raw representation. Unsafe methods to convert back are not provided because they are rarely used and too numerous to write an implementation for each (not much of a common pattern).
