2016-05-28Rollup merge of #33831 - diwic:patch-1, r=aturonManish Goregaokar-35/+35
panic.rs: fix docs (recover -> catch_unwind) The current docs are a bit inconsistent. First, change all references of "recover" to "catch_unwind" because the function was renamed. Second, consistently use the term "unwind safe" instead of "panic safe", "exception safe" and "recover safe" (all these terms were used previously).

2016-05-09rustc: Implement custom panic runtimesAlex Crichton-6/+3
This commit is an implementation of [RFC 1513] which allows applications to alter the behavior of panics at compile time. A new compiler flag, `-C panic`, is added and accepts the values `unwind` or `panic`, with the default being `unwind`. This model affects how code is generated for the local crate, skipping generation of landing pads with `-C panic=abort`. [RFC 1513]: https://github.com/rust-lang/rfcs/blob/master/text/1513-less-unwinding.md Panic implementations are then provided by crates tagged with `#![panic_runtime]` and lazily required by crates with `#![needs_panic_runtime]`. The panic strategy (`-C panic` value) of the panic runtime must match the final product, and if the panic strategy is not `abort` then the entire DAG must have the same panic strategy. With the `-C panic=abort` strategy, users can expect a stable method to disable generation of landing pads, improving optimization in niche scenarios, decreasing compile time, and decreasing output binary size. With the `-C panic=unwind` strategy users can expect the existing ability to isolate failure in Rust code from the outside world. Organizationally, this commit dismantles the `sys_common::unwind` module in favor of some bits moving part of it to `libpanic_unwind` and the rest into the `panicking` module in libstd. The custom panic runtime support is pretty similar to the custom allocator support with the only major difference being how the panic runtime is injected (takes the `-C panic` flag into account).

Types like `&AssertRecoverSafe<T>` and `Rc<AssertRecoverSafe<T>>` were mistakenly not considered recover safe, but the point of the assertion wrapper is that it indeed is! This was caused by an interaction between the `RecoverSafe` and `NoUnsafeCell` marker traits, and this is updated by adding an impl of the `NoUnsafeCell` marker trait for `AssertRecoverSafe` to ensure that it never interacts with the other negative impls of `RecoverSafe`. cc #30510
