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). 2016-02-28T18:50:13+00:00 Alex Crichton alex@alexcrichton.com 2016-02-24T22:17:21+00:00 urn:sha1:52ec682776cbf66fee16609405eb03d672eb52c2 2016-02-21T17:49:13+00:00 Alex Crichton alex@alexcrichton.com 2016-02-21T17:49:13+00:00 urn:sha1:95761417c397f161d93e4df26ef1d1fc6da8cd69 The standard library doesn't depend on rustc_bitflags, so move it to explicit dependencies on all other crates. Additionally, the arena/fmt_macros deps could be dropped from libsyntax. 2016-02-11T18:42:28+00:00 Alex Crichton alex@alexcrichton.com 2015-11-19T23:20:12+00:00 urn:sha1:046e6874c47ec55e23b7a566bca51d2920562485 This commit is the start of a series of commits which start to replace the makefiles with a Cargo-based build system. The aim is not to remove the makefiles entirely just yet but rather just replace the portions that invoke the compiler to do the bootstrap. This commit specifically adds enough support to perform the bootstrap (and all the cross compilation within) along with generating documentation. More commits will follow up in this series to actually wire up the makefiles to call this build system, so stay tuned!
