2019-06-10std: Remove internal definitions of `cfg_if!` macroAlex Crichton-4/+1
This is duplicated in a few locations throughout the sysroot to work around issues with not exporting a macro in libstd but still wanting it available to sysroot crates to define blocks. Nowadays though we can simply depend on the `cfg-if` crate on crates.io, allowing us to use it from there!

The files src/libstd/sys/sgx/*.rs are mostly copied/adapted from the wasm target. This also updates the dlmalloc submodule to the very latest version.

2018-01-22Do not assume dynamic linking for musl/mips[el] targetsMarco A L Barbosa-1/+1
All musl targets except mips[el] assume static linking by default. This can be confusing https://users.rust-lang.org/t/static-cross-compiled-binaries-arent-really-static/6084 When the musl/mips[el] targets was [added](https://github.com/rust-lang/rust/pull/31298), dynamic linking was chosen because of binary size concerns, and probably also because libunwind [didn't](https://users.rust-lang.org/t/static-cross-compiled-binaries-arent-really-static/6084/8) supported mips. Now that we have `crt-static` target-feature (the user can choose dynamic link for musl targets), and libunwind [6.0](https://github.com/llvm-mirror/libunwind/commits/release_60) add support to mips, we do not need to assume dynamic linking.
2017-11-19std: Add a new wasm32-unknown-unknown targetAlex Crichton-6/+13
This commit adds a new target to the compiler: wasm32-unknown-unknown. This target is a reimagining of what it looks like to generate WebAssembly code from Rust. Instead of using Emscripten which can bring with it a weighty runtime this instead is a target which uses only the LLVM backend for WebAssembly and a "custom linker" for now which will hopefully one day be direct calls to lld. Notable features of this target include: * There is zero runtime footprint. The target assumes nothing exists other than the wasm32 instruction set. * There is zero toolchain footprint beyond adding the target. No custom linker is needed, rustc contains everything. * Very small wasm modules can be generated directly from Rust code using this target. * Most of the standard library is stubbed out to return an error, but anything related to allocation works (aka `HashMap`, `Vec`, etc). * Naturally, any `#[no_std]` crate should be 100% compatible with this new target. This target is currently somewhat janky due to how linking works. The "linking" is currently unconditional whole program LTO (aka LLVM is being used as a linker). Naturally that means compiling programs is pretty slow! Eventually though this target should have a linker. This target is also intended to be quite experimental. I'm hoping that this can act as a catalyst for further experimentation in Rust with WebAssembly. Breaking changes are very likely to land to this target, so it's not recommended to rely on it in any critical capacity yet. We'll let you know when it's "production ready". --- Currently testing-wise this target is looking pretty good but isn't complete. I've got almost the entire `run-pass` test suite working with this target (lots of tests ignored, but many passing as well). The `core` test suite is still getting LLVM bugs fixed to get that working and will take some time. Relatively simple programs all seem to work though! --- It's worth nothing that you may not immediately see the "smallest possible wasm module" for the input you feed to rustc. For various reasons it's very difficult to get rid of the final "bloat" in vanilla rustc (again, a real linker should fix all this). For now what you'll have to do is: cargo install --git https://github.com/alexcrichton/wasm-gc wasm-gc foo.wasm bar.wasm And then `bar.wasm` should be the smallest we can get it! --- In any case for now I'd love feedback on this, particularly on the various integration points if you've got better ideas of how to approach them!

2017-08-24Do not assume libunwind.a is availableSamuel Holland-2/+2
2017-08-22Update libunwind dependencies for muslSamuel Holland-0/+6
Use libgcc_s when linking dynamically. Convert the static libunwind to static-nobundle, as libunwind.a is copied from musl_root and available in the library search path.
2017-03-30libgcc_eh may depend on libpthread.Vadim Chugunov-0/+1
Make sure we link to the static libpthread, so that compiled Rust binaries do not depend on winpthread1.dll.
2016-12-29Remove not(stage0) from deny(warnings)Alex Crichton-1/+1
Historically this was done to accommodate bugs in lints, but there hasn't been a bug in a lint since this feature was added which the warnings affected. Let's completely purge warnings from all our stages by denying warnings in all stages. This will also assist in tracking down `stage0` code to be removed whenever we're updating the bootstrap compiler.

2016-05-09rustc: Implement custom panic runtimesAlex Crichton-0/+30
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).
