These new intrinsics are comparable to `atomic_signal_fence` in C++, ensuring the compiler will not reorder memory accesses across the barrier, nor will it emit any machine instructions for it. Closes rust-lang#24118, implementing RFC 888.
The error in the Brief Introduction shows the problematic line as "x.push(4)", while the example code uses a vector of strings.
Also, remove the other brackets, because they make the whole sentence look awkward.
This commit is an implementation of [RFC 1044][rfc] which adds additional surface area to the `std::fs` module. All new APIs are `#[unstable]` behind assorted feature names for each one. [rfc]: rust-lang/rfcs#1044 The new APIs added are: * `fs::canonicalize` - bindings to `realpath` on unix and `GetFinalPathNameByHandle` on windows. * `fs::symlink_metadata` - similar to `lstat` on unix * `fs::FileType` and accessor methods as `is_{file,dir,symlink}` * `fs::Metadata::file_type` - accessor for the raw file type * `fs::DirEntry::metadata` - acquisition of metadata which is free on Windows but requires a syscall on unix. * `fs::DirEntry::file_type` - access the file type which may not require a syscall on most platforms. * `fs::DirEntry::file_name` - access just the file name without leading components. * `fs::PathExt::symlink_metadata` - convenience method for the top-level function. * `fs::PathExt::canonicalize` - convenience method for the top-level function. * `fs::PathExt::read_link` - convenience method for the top-level function. * `fs::PathExt::read_dir` - convenience method for the top-level function. * `std::os::raw` - type definitions for raw OS/C types available on all platforms. * `std::os::$platform` - new modules have been added for all currently supported platforms (e.g. those more specific than just `unix`). * `std::os::$platform::raw` - platform-specific type definitions. These modules are populated with the bare essentials necessary for lowing I/O types into their raw representations, and currently largely consist of the `stat` definition for unix platforms. This commit also deprecates `Metadata::{modified, accessed}` in favor of inspecting the raw representations via the lowering methods of `Metadata`.
This error indicates that a constant references itself. All constants need to resolve to a value in an acyclic manner. For example, neither of the following can be sensibly compiled: ``` const X: u32 = X; ``` ``` const X: u32 = Y; const Y: u32 = X; ```
This is served by stability markers.
This is the last remaining portion of rust-lang#24796
The "unchecked_" div and rem functions will give UB in case of rhs == 0, or, in the signed versions, lhs == INT::min and rhs == -1
…24687-test Add `-g` (to testcase) that I should have included in PR rust-lang#24932. Note it is safe, with respect to autobuilds, to land before rust-lang#24945. (In other words, landing this sooner won't break things for anyone any worse than they were already broken, since there are *other* tests that also add `-g` to their flags via `compile-flags: -g`.)
This is OK to do given: - PIE is supported on Android starting with API 16. - The bots are running API 18. - API < 16 now has a 12.5% market share[0] as of 2015-04-29. Closes rust-lang#17437. [0] https://developer.android.com/about/dashboards/index.html r? @alexcrichton
Changes made include adding missing punctuation, adding missing words, and converting uses of "Gets" to "Returns" in libstd/net/addr.rs to make it more consistent with the other documentation. Fixes rust-lang#24925.
r? @alexcrichton I've tested these locally, so they should all be good to go.
