Fix undefined behavior From the [`MaybeUninit::get_mut` docs](https://doc.rust-lang.org/std/mem/union.MaybeUninit.html): > It is up to the caller to guarantee that the the MaybeUninit really is in an initialized state, otherwise this will immediately cause undefined behavior. r? @joshtriplett

VardhanThigle:Vardhan/x86_64-fortanix-unknown-sgx-backtrace-support, r=alexcrichton Supporting backtrace for x86_64-fortanix-unknown-sgx. # Overview Implementing following functions required by `libstd/sys_common` to support `backtrace`: ``` 1. unwind_backtrace 2. trace_fn 3. resolve_symname ``` # Description: The changes here are quite similar to the Cloudabi target `src/libstd/sys/cloudabi/backtrace.rs` The first 2 functions are implemented via calls to libunwind.a that is linked to the `x86_64-fortanix-unknown-sgx` (#56979), we have not implemented functionality needed by `resolve_symname` (or `dladdr`) to reduce SGX TCB. Rather, we print the function address (relative to enclave image base) in `resolve_symname` which can be later translated to correct symbol name (say, via `addr2line`). # Note: For `x86_64-fortanix-unknown-sgx`, the `RUST_BACKTRACE` environment has to be set from within the program running in an enclave. cc: @jethrogb r? @alexcrichton

2019-01-08Auto merge of #56988 - alexcrichton:monotonic-instant, r=sfacklerbors-13/+101
std: Force `Instant::now()` to be monotonic This commit is an attempt to force `Instant::now` to be monotonic through any means possible. We tried relying on OS/hardware/clock implementations, but those seem buggy enough that we can't rely on them in practice. This commit implements the same hammer Firefox recently implemented (noted in #56612) which is to just keep whatever the lastest `Instant::now()` return value was in memory, returning that instead of the OS looks like it's moving backwards. Closes #48514 Closes #49281 cc #51648 cc #56560 Closes #56612 Closes #56940

Add duration constants Add constants `SECOND`, `MILLISECOND`, `MICROSECOND`, and `NANOSECOND` to `core::time`. This will make working with durations more ergonomic. Compare: ```rust // Convenient, but deprecated function. thread::sleep_ms(2000); // The current canonical way to sleep for two seconds. thread::sleep(Duration::from_secs(2)); // Sleeping using one of the new constants. thread::sleep(2 * SECOND); ```

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.
