rust/src/libstd/sys, branch 1.4.0

Auto merge of #28358 - dotdash:nounwind, r=alexcrichton

2015-09-14T11:05:34+00:00

This allows to skip the codegen for all the unneeded landing pads, reducing code size across the board by about 2-5%, depending on the crate. Compile times seem to be pretty unaffected though :-/

Mark all extern functions as nounwind

2015-09-14T09:36:09+00:00

Unwinding across an FFI boundary is undefined behaviour, so we can mark all external function as nounwind. The obvious exception are those functions that actually perform the unwinding.

std: Internalize almost all of `std::rt`

2015-09-11T18:19:20+00:00

This commit does some refactoring to make almost all of the `std::rt` private. Specifically, the following items are no longer part of its API: * DEFAULT_ERROR_CODE * backtrace * unwind * args * at_exit * cleanup * heap (this is just alloc::heap) * min_stack * util The module is now tagged as `#[doc(hidden)]` as the only purpose it's serve is an entry point for the `panic!` macro via the `begin_unwind` and `begin_unwind_fmt` reexports.

std: Stabilize/deprecate features for 1.4

2015-09-11T16:48:48+00:00

Let's see if lifetime elision works in this case

2015-09-08T06:05:59+00:00

Fixed required type coercion

2015-09-08T05:41:50+00:00

I'd have thought that the types of the slice::Split would have been inferred, but this appears not to be the case. Reverted this one change.
