2017-11-08Auto merge of #45379 - cuviper:unit_from_iter, r=alexcrichtonbors-0/+1
impl FromIterator<()> for () This just collapses all unit items from an iterator into one. This is more useful when combined with higher-level abstractions, like collecting to a `Result<(), E>` where you only care about errors: ```rust use std::io::*; data = vec![1, 2, 3, 4, 5]; let res: Result<()> = data.iter() .map(|x| writeln!(stdout(), "{}", x)) .collect(); assert!(res.is_ok()); ```

2017-05-12Remove some unused macros from the rust codebaseest31-4/+0
Removes unused macros from: * libcore * libcollections The last use of these two macros was removed in commit b64c9d56700e2c41207166fe8709711ff02488ff when the char_range_at_reverse function was been removed. * librustc_errors Their last use was removed by commits 2f2c3e178325dc1837badcd7573c2c0905fab979 and 11dc974a38fd533aa692cea213305056cd3a6902. * libsyntax_ext * librustc_trans Also, put the otry macro in back/msvc/mod.rs under the same cfg argument as the places that use it.

2017-01-08Auto merge of #38679 - alexcrichton:always-deny-warnings, r=nrcbors-1/+1
Remove not(stage0) from deny(warnings) Historically this was done to accommodate bugs in lints, but there hasn't been a bug in a lint since this feature was added which the warnings affected. Let's completely purge warnings from all our stages by denying warnings in all stages. This will also assist in tracking down `stage0` code to be removed whenever we're updating the bootstrap compiler.

2016-12-30Such large. Very 128. Much bits.Simonas Kazlauskas-0/+8
This commit introduces 128-bit integers. Stage 2 builds and produces a working compiler which understands and supports 128-bit integers throughout. The general strategy used is to have rustc_i128 module which provides aliases for iu128, equal to iu64 in stage9 and iu128 later. Since nowhere in rustc we rely on large numbers being supported, this strategy is good enough to get past the first bootstrap stages to end up with a fully working 128-bit capable compiler. In order for this strategy to work, number of locations had to be changed to use associated max_value/min_value instead of MAX/MIN constants as well as the min_value (or was it max_value?) had to be changed to use xor instead of shift so both 64-bit and 128-bit based consteval works (former not necessarily producing the right results in stage1). This commit includes manual merge conflict resolution changes from a rebase by @est31.

2016-08-17Rollup merge of #35663 - CryZe:no-stdlib, r=ManishearthJonathan Turner-0/+5
Improve `No stdlib` and related Documentation This renames all lang item function names to the ones used in `libstd` and `libpanic_unwind`. It also explains the `eh_unwind_resume` lang item in the `libcore` documentation, where it was missing. A third function is also needed on certain compilation targets, so this was also added to the `No stdlib` documentation.

2016-07-23Escape fewer Unicode codepoints in `Debug` impl of `str`Tobias Bucher-0/+1
Use the same procedure as Python to determine whether a character is printable, described in [PEP 3138]. In particular, this means that the following character classes are escaped: - Cc (Other, Control) - Cf (Other, Format) - Cs (Other, Surrogate), even though they can't appear in Rust strings - Co (Other, Private Use) - Cn (Other, Not Assigned) - Zl (Separator, Line) - Zp (Separator, Paragraph) - Zs (Separator, Space), except for the ASCII space `' '` (`0x20`) This allows for user-friendly inspection of strings that are not English (e.g. compare `"\u{e9}\u{e8}\u{ea}"` to `"éèê"`). Fixes #34318. [PEP 3138]: https://www.python.org/dev/peps/pep-3138/
2016-07-15Fix up documentation around no_stdSteve Klabnik-5/+8
1. Fix the sections in the book to have the correct signatures. I've also marked them as `ignore`; there's no way to set the `no_std` feature for libc, so it pulls in the stdlib, so this wasn't even testing the actual thing it was testing. Better to just ignore. 2. Correcting libcore's docs for factual inaccuracy, and add a note about language items. Fixes #33677
2016-07-03std: Stabilize APIs for the 1.11.0 releaseAlex Crichton-0/+2
Although the set of APIs being stabilized this release is relatively small, the trains keep going! Listed below are the APIs in the standard library which have either transitioned from unstable to stable or those from unstable to deprecated. Stable * `BTreeMap::{append, split_off}` * `BTreeSet::{append, split_off}` * `Cell::get_mut` * `RefCell::get_mut` * `BinaryHeap::append` * `{f32, f64}::{to_degrees, to_radians}` - libcore stabilizations mirroring past libstd stabilizations * `Iterator::sum` * `Iterator::product` Deprecated * `{f32, f64}::next_after` * `{f32, f64}::integer_decode` * `{f32, f64}::ldexp` * `{f32, f64}::frexp` * `num::One` * `num::Zero` Added APIs (all unstable) * `iter::Sum` * `iter::Product` * `iter::Step` - a few methods were added to accomodate deprecation of One/Zero Removed APIs * `From<Range<T>> for RangeInclusive<T>` - everything about `RangeInclusive` is unstable Closes #27739 Closes #27752 Closes #32526 Closes #33444 Closes #34152 cc #34529 (new tracking issue)

2016-05-31mk: Prepare for a new stage0 compilerAlex Crichton-1/+0
This commit prepares the source for a new stage0 compiler, the 1.10.0 beta compiler. These artifacts are hot off the bots and should be ready to go.
2016-05-13Fix fast path of float parsing on x87Andrea Canciani-0/+2
The fast path of the float parser relies on the rounding to happen exactly and directly to the correct number of bits. On x87, instead, double rounding would occour as the FPU stack defaults to 80 bits of precision. This can be fixed by setting the precision of the FPU stack before performing the int to float conversion. This can be achieved by changing the value of the x87 control word. This is a somewhat common operation that is in fact performed whenever a float needs to be truncated to an integer, but it is undesirable to add its overhead for code that does not rely on x87 for computations (i.e. on non-x86 architectures, or x86 architectures which perform FPU computations on using SSE). Fixes `num::dec2flt::fast_path_correct` (on x87).

2016-04-05Specialize equality for [T] and comparison for [u8]Ulrik Sverdrup-0/+1
Where T is a type that can be compared for equality bytewise, we can use memcmp. We can also use memcmp for PartialOrd, Ord for [u8] and by extension &str. This is an improvement for example for the comparison [u8] == [u8] that used to emit a loop that compared the slices byte by byte. One worry here could be that this introduces function calls to memcmp in contexts where it should really inline the comparison or even optimize it out, but llvm takes care of recognizing memcmp specifically.

2016-01-24mk: Move from `-D warnings` to `#![deny(warnings)]`Alex Crichton-0/+1
This commit removes the `-D warnings` flag being passed through the makefiles to all crates to instead be a crate attribute. We want these attributes always applied for all our standard builds, and this is more amenable to Cargo-based builds as well. Note that all `deny(warnings)` attributes are gated with a `cfg(stage0)` attribute currently to match the same semantics we have today

2015-12-05std: Stabilize APIs for the 1.6 releaseAlex Crichton-9/+4
This commit is the standard API stabilization commit for the 1.6 release cycle. The list of issues and APIs below have all been through their cycle-long FCP and the libs team decisions are listed below Stabilized APIs * `Read::read_exact` * `ErrorKind::UnexpectedEof` (renamed from `UnexpectedEOF`) * libcore -- this was a bit of a nuanced stabilization, the crate itself is now marked as `#[stable]` and the methods appearing via traits for primitives like `char` and `str` are now also marked as stable. Note that the extension traits themeselves are marked as unstable as they're imported via the prelude. The `try!` macro was also moved from the standard library into libcore to have the same interface. Otherwise the functions all have copied stability from the standard library now. * The `#![no_std]` attribute * `fs::DirBuilder` * `fs::DirBuilder::new` * `fs::DirBuilder::recursive` * `fs::DirBuilder::create` * `os::unix::fs::DirBuilderExt` * `os::unix::fs::DirBuilderExt::mode` * `vec::Drain` * `vec::Vec::drain` * `string::Drain` * `string::String::drain` * `vec_deque::Drain` * `vec_deque::VecDeque::drain` * `collections::hash_map::Drain` * `collections::hash_map::HashMap::drain` * `collections::hash_set::Drain` * `collections::hash_set::HashSet::drain` * `collections::binary_heap::Drain` * `collections::binary_heap::BinaryHeap::drain` * `Vec::extend_from_slice` (renamed from `push_all`) * `Mutex::get_mut` * `Mutex::into_inner` * `RwLock::get_mut` * `RwLock::into_inner` * `Iterator::min_by_key` (renamed from `min_by`) * `Iterator::max_by_key` (renamed from `max_by`) Deprecated APIs * `ErrorKind::UnexpectedEOF` (renamed to `UnexpectedEof`) * `OsString::from_bytes` * `OsStr::to_cstring` * `OsStr::to_bytes` * `fs::walk_dir` and `fs::WalkDir` * `path::Components::peek` * `slice::bytes::MutableByteVector` * `slice::bytes::copy_memory` * `Vec::push_all` (renamed to `extend_from_slice`) * `Duration::span` * `IpAddr` * `SocketAddr::ip` * `Read::tee` * `io::Tee` * `Write::broadcast` * `io::Broadcast` * `Iterator::min_by` (renamed to `min_by_key`) * `Iterator::max_by` (renamed to `max_by_key`) * `net::lookup_addr` New APIs (still unstable) * `<[T]>::sort_by_key` (added to mirror `min_by_key`) Closes #27585 Closes #27704 Closes #27707 Closes #27710 Closes #27711 Closes #27727 Closes #27740 Closes #27744 Closes #27799 Closes #27801 cc #27801 (doesn't close as `Chars` is still unstable) Closes #28968
