2017-06-08std: Avoid panics in rust_eh_personalityAlex Crichton-23/+32
This commit removes a few calls to panic and/or assert in `rust_eh_personality`. This function definitely can't itself panic (that'd probably segfault or do something else weird) and I was also noticing that a `pub extern fn foo() {}` cdylib was abnormally large. Turns out all that size was the panicking machinery brought in by the personality function! The change here is to return a `Result` internally so we can bubble up the fatal error, eventually translating to the appropriate error code for the libunwind ABI.

Well, not quite: ARM EHABI platforms still use the old scheme -- for now.

2016-05-09rustc: Implement custom panic runtimesAlex Crichton-0/+264
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).
