2016-05-24std: Stabilize APIs for the 1.10 releaseAlex Crichton-4/+7
This commit applies the FCP decisions made by the libs team for the 1.10 cycle, including both new stabilizations and deprecations. Specifically, the list of APIs is: Stabilized: * `os::windows::fs::OpenOptionsExt::access_mode` * `os::windows::fs::OpenOptionsExt::share_mode` * `os::windows::fs::OpenOptionsExt::custom_flags` * `os::windows::fs::OpenOptionsExt::attributes` * `os::windows::fs::OpenOptionsExt::security_qos_flags` * `os::unix::fs::OpenOptionsExt::custom_flags` * `sync::Weak::new` * `Default for sync::Weak` * `panic::set_hook` * `panic::take_hook` * `panic::PanicInfo` * `panic::PanicInfo::payload` * `panic::PanicInfo::location` * `panic::Location` * `panic::Location::file` * `panic::Location::line` * `ffi::CStr::from_bytes_with_nul` * `ffi::CStr::from_bytes_with_nul_unchecked` * `ffi::FromBytesWithNulError` * `fs::Metadata::modified` * `fs::Metadata::accessed` * `fs::Metadata::created` * `sync::atomic::Atomic{Usize,Isize,Bool,Ptr}::compare_exchange` * `sync::atomic::Atomic{Usize,Isize,Bool,Ptr}::compare_exchange_weak` * `collections::{btree,hash}_map::{Occupied,Vacant,}Entry::key` * `os::unix::net::{UnixStream, UnixListener, UnixDatagram, SocketAddr}` * `SocketAddr::is_unnamed` * `SocketAddr::as_pathname` * `UnixStream::connect` * `UnixStream::pair` * `UnixStream::try_clone` * `UnixStream::local_addr` * `UnixStream::peer_addr` * `UnixStream::set_read_timeout` * `UnixStream::set_write_timeout` * `UnixStream::read_timeout` * `UnixStream::write_Timeout` * `UnixStream::set_nonblocking` * `UnixStream::take_error` * `UnixStream::shutdown` * Read/Write/RawFd impls for `UnixStream` * `UnixListener::bind` * `UnixListener::accept` * `UnixListener::try_clone` * `UnixListener::local_addr` * `UnixListener::set_nonblocking` * `UnixListener::take_error` * `UnixListener::incoming` * RawFd impls for `UnixListener` * `UnixDatagram::bind` * `UnixDatagram::unbound` * `UnixDatagram::pair` * `UnixDatagram::connect` * `UnixDatagram::try_clone` * `UnixDatagram::local_addr` * `UnixDatagram::peer_addr` * `UnixDatagram::recv_from` * `UnixDatagram::recv` * `UnixDatagram::send_to` * `UnixDatagram::send` * `UnixDatagram::set_read_timeout` * `UnixDatagram::set_write_timeout` * `UnixDatagram::read_timeout` * `UnixDatagram::write_timeout` * `UnixDatagram::set_nonblocking` * `UnixDatagram::take_error` * `UnixDatagram::shutdown` * RawFd impls for `UnixDatagram` * `{BTree,Hash}Map::values_mut` * `<[_]>::binary_search_by_key` Deprecated: * `StaticCondvar` - this, and all other static synchronization primitives below, are usable today through the lazy-static crate on stable Rust today. Additionally, we'd like the non-static versions to be directly usable in a static context one day, so they're unlikely to be the final forms of the APIs in any case. * `CONDVAR_INIT` * `StaticMutex` * `MUTEX_INIT` * `StaticRwLock` * `RWLOCK_INIT` * `iter::Peekable::is_empty` Closes #27717 Closes #27720 cc #27784 (but encode methods still exist) Closes #30014 Closes #30425 Closes #30449 Closes #31190 Closes #31399 Closes #31767 Closes #32111 Closes #32281 Closes #32312 Closes #32551 Closes #33018

r=alexcrichton Update i686-linux-android features to match android x86 ABI. Based on [android's official x86 ABI info](http://developer.android.com/ndk/guides/abis.html#x86), the x86 baseline CPU can be safely updated to `pentiumpro`, with the addition of `MMX`, `SSE`, `SSE2`, `SSE3`, `SSSE3` features. r? @alexcrichton

Add armv7-linux-androideabi target This PR adds `armv7-linux-androideabi` target that matches `armeabi-v7a` Android ABI, ~~downscales `arm-linux-androideabi` target to match `armeabi` Android ABI~~ (TBD later if needed). This should allow us to get the best performance from every [Android ABI level](http://developer.android.com/ndk/guides/abis.html). Currently existing target `arm-linux-androideabi` started gaining features out of the supported range of [android `armeabi`](http://developer.android.com/ndk/guides/abis.html). While android compiler does not use a different target for later supported `armv7` architecture, it has distinct ABI name `armeabi-v7a`. We decided to add rust target `armv7-linux-androideabi` to match it. Note that `NEON`, `VFPv3-D32`, and `ThumbEE` instruction sets are not added, because not all android devices are guaranteed to support all or some of these, and [their availability should be checked at runtime](http://developer.android.com/ndk/guides/abis.html#v7a). ~~This reduces performance of existing `arm-linux-androideabi` and may make it _much_ slower (we are talking more than order of magnitude in some random ad-hoc fp benchmark that I did).~~ Part of #33278.

rustc: Change target_env for ARM targets to `gnu` Right now they're `gnueabihf` and `gnueabi`, but when adding new platforms like musl on ARM it's unfortunate to have to test for all three (`musl`, `musleabi`, and `musleabihf`).

Removes all unstable and deprecated APIs prior to the 1.8 release. All APIs that are deprecated in the 1.8 release are sticking around for the rest of this cycle. Some notable changes are: * The `dynamic_lib` module was moved into `rustc_back` as the compiler still relies on a few bits and pieces. * The `DebugTuple` formatter now special-cases an empty struct name with only one field to append a trailing comma.
2016-03-10Auto merge of #32034 - alexcrichton:old-x86-msvc, r=aturonbors-14/+23
rustc: Add an i586-pc-windows-msvc target Similarly to #31629 where an i586-unknown-linux-gnu target was added, there is sometimes a desire to compile for x86 Windows as well where SSE2 is disabled. This commit mirrors the i586-unknown-linux-gnu target and simply adds a variant for Windows as well. This is motivated by a recent [Gecko bug][ff] where crashes were seen on 32-bit Windows due to users having CPUs that don't support SSE2 instructions. It was requested that we could have non-SSE2 builds of the standard library available so they could continue to use vanilla releases and nightlies.

A whole bunch of stuff gets folded into struct handling! Plus, removes an ugly hack from trans and accidentally fixes a bug with constructing ranges from references (see later commits with tests).
2016-02-26Use .copy_from_slice() where applicableUlrik Sverdrup-3/+4
.copy_from_slice() does the same job of .clone_from_slice(), but the former is explicitly for Copy elements and calls `memcpy` directly, and thus is it efficient without optimization too.
2016-02-23Auto merge of #31814 - petevine:master, r=alexcrichtonbors-1/+1
The `vfp2` option was a leftover from `armv6` compatibility features of the original armhf target. Gcc defaults to `vfp3`on `armv7` hard-float linux systems so we should make it the default for rustc too.
