Bound sgx target_env with fortanix as target_vendor This PR adds `target_vendor` check, as discussed in issue [57231](https://github.com/rust-lang/rust/issues/57231) Signed-off-by: Yu Ding <dingelish@gmail.com>
2019-01-02Auto merge of #56827 - faern:eliminate-recv-timeout-panic, r=KodrAusbors-6/+30
Eliminate Receiver::recv_timeout panic Fixes #54552. This panic is because `recv_timeout` uses `Instant::now() + timeout` internally. This possible panic is not mentioned in the documentation for this method. Very recently we merged (still unstable) support for checked addition (#56490) of `Instant + Duration`, so it's now finally possible to add these together without risking a panic.

Add `io` and `arch` modules to `std::os::fortanix_sgx` This PR adds two more (unstable) modules to `std::os::fortanix_sgx` for the `x86_64-fortanix-unknown-sgx` target. ### io `io` allows conversion between raw file descriptors and Rust types, similar to `std::os::unix::io`. ### arch `arch` exposes the `ENCLU[EREPORT]` and `ENCLU[EGETKEY]` instructions. The current functions are very likely not going to be the final form of these functions (see also https://github.com/fortanix/rust-sgx/issues/15), but this should be sufficient to enable experimentation in libraries. I tried using the actual types (from the [`sgx-isa` crate](https://crates.io/crates/sgx-isa)) instead of byte arrays, but that would make `std` dependent on the `bitflags` crate which I didn't want to do at this time.

2018-12-24std: Use backtrace-sys from crates.ioAlex Crichton-129/+34
This commit switches the standard library to using the `backtrace-sys` crate from crates.io instead of duplicating the logic here in the Rust repositor with the `backtrace-sys`'s crate's logic. Eventually this will hopefully be a good step towards using the `backtrace` crate directly from crates.io itself, but we're not quite there yet! Hopefully this is a small incremental first step we can take.

Add `std::os::fortanix_sgx` module This PR adds the `std::os::sgx` module to expose platform-specific APIs behind the `sgx_platform` feature gate. Depends on https://github.com/rust-lang/rust/pull/56972 to be able to meaningfully build `std::os` documentation for non-standard targets.

Pin stabilization This implements the changes suggested in https://github.com/rust-lang/rust/issues/55766#issue-378417538 and stabilizes the `pin` feature. @alexcrichton also listed several "blockers" in that issue, but then in [this comment](https://github.com/rust-lang/rust/issues/55766#issuecomment-445074980) mentioned that they're more "TODO items": > In that vein I think it's fine for a stabilization PR to be posted at any time now with FCP lapsed for a week or so now. The final points about self/pin/pinned can be briefly discussed there (if even necessary, they could be left as the proposal above). Let's settle these last bits here and get this thing stabilized! :) r? @alexcrichton cc @withoutboats

2018-12-23Rollup merge of #56979 - VardhanThigle:Vardhan/rust-sgx-unwind-support, ↵kennytm-6/+139
r=alexcrichton Adding unwinding support for x86_64_fortanix_unknown_sgx target. Unwinding support is provided by our port of LLVM's libunwind which is available from https://github.com/fortanix/libunwind/tree/release_50. libunwind requires support for rwlock and printing to stderr, which is only provided by `std` for this target. This poses two problems: 1) how to expose the `std` functionality to C and 2) dependency inversion. ### Exposing `std` For exposing the functionality we chose to expose the following symbols: * __rust_rwlock_rdlock * __rust_rwlock_wrlock * __rust_rwlock_unlock * __rust_print_err * __rust_abort Also, the following are needed from `alloc`: * __rust_alloc * __rust_dealloc #### Rust RWLock in C In `libunwind`, RWLock is initialized as a templated static variable: ```c pthread_rwlock_t DwarfFDECache<A>::_lock = PTHREAD_RWLOCK_INITIALIZER; ``` I don't know of a good way to use the Rust sys::rwlock::RWLock type and initializer there. We could have a static global variable in Rust, but that doesn't work with the templating. The variable needs to be initialized statically, since this target doesn't support the .init section. Currently, I just used a byte array and standard C array initialization. The mapping between this C type and the Rust type needs to be manually maintained. There is a compile-time check and a unit test to make sure the Rust versions of these C definitions match the actual Rust type. If any reviewer knows of a better solution, please do tell. ### Dependency inversion issue `std` depends on `panic_unwind` which depends on `libunwind`, and `libunwind` depends on `std`. This is not normally supported by Rust's linking system. Therefore we use raw C exports from `std` *and* `libunwind.a` is linked last in the target `post_link_objects` instead of being built as part of the Rust `libunwind`. Currently, all C exports are defined in `src/libstd/sys/sgx/rwlock.rs` to overcome LTO issues. Only the `__rust_rwlock_*` definitions *need* to live there for privacy reasons. Once again, if any reviewer knows of a better solution, please do tell. r? @alexcrichton

Always run rustc in a thread cc @ishitatsuyuki @eddyb r? @pnkfelix [Previously](https://github.com/rust-lang/rust/pull/48575) we moved to only producing threads when absolutely necessary. Even before we opted to only create threads in some cases, which [is unsound](https://github.com/rust-lang/rust/pull/48575#issuecomment-380635967) due to the way we use thread local storage.
