2019-10-05Rollup merge of #64765 - alexcrichton:less-check-backtrace, r=sfacklerTyler Mandry-3/+0
std: Reduce checks for `feature = "backtrace"` This is a stylistic change to libstd to reduce the number of checks of `feature = "backtrace"` now that we unconditionally depend on the `backtrace` crate and rely on it having an empty implementation. otherwise.

macos tlv workaround fixes: #60141 Includes: * remove dead code: `requires_move_before_drop`. This hasn't been needed for a while now (oops I should have removed it in #57655) * redox had a copy of `fast::Key` (not sure why?). That has been removed. * Perform a `read_volatile` on OSX to reduce `tlv_get_addr` calls per `__getit` from (4-2 depending on context) to 1. `tlv_get_addr` is relatively expensive (~1.5ns on my machine). Previously, in contexts where `__getit` was inlined, 4 calls to `tlv_get_addr` were performed per lookup. For some reason when `__getit` is not inlined this is reduced to 2x - and performance improves to match. After this PR, I have only ever seen 1x call to `tlv_get_addr` per `__getit`, and macos now benefits from situations where `__getit` is inlined. I'm not sure if the `read_volatile(&&__KEY)` trick is working around an LLVM bug, or a rustc bug, or neither. r? @alexcrichton

2019-03-03race condition in thread local storage examplebenaryorg-1/+4
The example had a potential race condition that would still pass the test. If the thread which was supposed to modify it's own thread local was slower than the instruction to modify in the main thread, then the test would pass even in case of a failure. This is would be minor if the child thread was waited for since it check using an `assert_eq` for the same thing, but vice versa. However, if the `assert_eq` failed this would trigger a panic, which is not at all caught by the example since the thread is not waited on. Signed-off-by: benaryorg <binary@benary.org>

Cosmetic improvements to doc comments This has been factored out from https://github.com/rust-lang/rust/pull/58036 to only include changes to documentation comments (throughout the rustc codebase). r? @steveklabnik Once you're happy with this, maybe we could get it through with r=1, so it doesn't constantly get invalidated? (I'm not sure this will be an issue, but just in case...) Anyway, thanks for your advice so far!

2018-11-06Rollup merge of #55597 - alexcrichton:thread-local-inner, r=KodrAuskennytm-4/+4
std: Enable usage of `thread_local!` through imports The `thread_local!` macro delegated to an internal macro but it didn't do so in a macros-and-the-module-system compatible fashion, meaning if a `#![no_std]` crate imported `std` and tried to use `thread_local!` it would fail due to missing a lookup of an internal macro. This commit switches the macro to instead use `$crate` to invoke other macros, ensuring that it'll work when `thread_local!` is imported alone.

2018-11-01std: Improve codegen size of accessing TLSAlex Crichton-1/+10
Some code in the TLS implementation in libstd stores `Some(val)` into an `&mut Option<T>` (effectively) and then pulls out `&T`, but it currently uses `.unwrap()` which can codegen into a panic even though it can never panic. With sufficient optimizations enabled (like LTO) the compiler can see through this but this commit helps it along in normal mode (`--release` with Cargo by default) to avoid codegen'ing the panic path. This ends up improving the optimized codegen on wasm by ensuring that a call to panic pulling in more file size doesn't stick around.
