2016-04-24syntax: Merge keywords and remaining special idents in one listVadim Petrochenkov-10/+8
Simplify the macro used for generation of keywords Make `Keyword::ident` private

2016-04-22Remove the MacroVisitor pass.Leo Testard-30/+64
This pass was supposed to check use of gated features before `#[cfg]`-stripping but this was not the case since it in fact happens after. Checks that are actually important and must be done before macro expansion are now made where the features are actually used. Close #32648. Also ensure that attributes on macro-generated macro invocations are checked as well. Close #32782 and #32655.

2016-04-11std: Stabilize APIs for the 1.9 releaseAlex Crichton-6/+6
This commit applies all stabilizations, renamings, and deprecations that the library team has decided on for the upcoming 1.9 release. All tracking issues have gone through a cycle-long "final comment period" and the specific APIs stabilized/deprecated are: Stable * `std::panic` * `std::panic::catch_unwind` (renamed from `recover`) * `std::panic::resume_unwind` (renamed from `propagate`) * `std::panic::AssertUnwindSafe` (renamed from `AssertRecoverSafe`) * `std::panic::UnwindSafe` (renamed from `RecoverSafe`) * `str::is_char_boundary` * `<*const T>::as_ref` * `<*mut T>::as_ref` * `<*mut T>::as_mut` * `AsciiExt::make_ascii_uppercase` * `AsciiExt::make_ascii_lowercase` * `char::decode_utf16` * `char::DecodeUtf16` * `char::DecodeUtf16Error` * `char::DecodeUtf16Error::unpaired_surrogate` * `BTreeSet::take` * `BTreeSet::replace` * `BTreeSet::get` * `HashSet::take` * `HashSet::replace` * `HashSet::get` * `OsString::with_capacity` * `OsString::clear` * `OsString::capacity` * `OsString::reserve` * `OsString::reserve_exact` * `OsStr::is_empty` * `OsStr::len` * `std::os::unix::thread` * `RawPthread` * `JoinHandleExt` * `JoinHandleExt::as_pthread_t` * `JoinHandleExt::into_pthread_t` * `HashSet::hasher` * `HashMap::hasher` * `CommandExt::exec` * `File::try_clone` * `SocketAddr::set_ip` * `SocketAddr::set_port` * `SocketAddrV4::set_ip` * `SocketAddrV4::set_port` * `SocketAddrV6::set_ip` * `SocketAddrV6::set_port` * `SocketAddrV6::set_flowinfo` * `SocketAddrV6::set_scope_id` * `<[T]>::copy_from_slice` * `ptr::read_volatile` * `ptr::write_volatile` * The `#[deprecated]` attribute * `OpenOptions::create_new` Deprecated * `std::raw::Slice` - use raw parts of `slice` module instead * `std::raw::Repr` - use raw parts of `slice` module instead * `str::char_range_at` - use slicing plus `chars()` plus `len_utf8` * `str::char_range_at_reverse` - use slicing plus `chars().rev()` plus `len_utf8` * `str::char_at` - use slicing plus `chars()` * `str::char_at_reverse` - use slicing plus `chars().rev()` * `str::slice_shift_char` - use `chars()` plus `Chars::as_str` * `CommandExt::session_leader` - use `before_exec` instead.

2016-03-27deriving: factor out discriminant_value constructionAlex Burka-37/+33
2016-03-27fix #21714 by using discriminant_value in #[derive(Hash)]Alex Burka-9/+12
This is the same approach taken in #24270, except that this should not be a breaking change because it only changes the output of hash functions, which nobody should be relying on.

to careful use of the span from deriving, we can permit it in stable code if it derives from deriving (not-even-a-pun intended)

It was originally intended to be i32, but it isn't. Fixes #31886.

2016-03-14Add `default` as contextual keyword, and parse it for impl items.Aaron Turon-0/+2
2016-03-14derive: improve hygiene for type parameters (see #2810)Alex Burka-17/+46
When deriving Hash, RustcEncodable and RustcDecodable, the syntax extension needs a type parameter to use in the inner method. They used to use __H, __S and __D respectively. If this conflicts with a type parameter already declared for the item, bad times result (see the test). There is no hygiene for type parameters, but this commit introduces a better heuristic by concatenating the names of all extant type parameters (and prepending __H).
2016-03-14derive: remove most __ strings FIXME(#2810)Alex Burka-48/+48
This changes local variable names in all derives to remove leading double-underscores. As far as I can tell, this doesn't break anything because there is no user code in these generated functions except for struct, field and type parameter names, and this doesn't cause shadowing of those. But I am still a bit nervous.
2016-03-14fix FIXME(#6449) in #[derive(PartialOrd, Ord)]Alex Burka-55/+48
This replaces some `if`s with `match`es. This was originally not possible because using a global path in a match statement caused a "non-constant path in constant expr" ICE. The issue is long since closed, though you still hit it (as an error now, not an ICE) if you try to generate match patterns using pat_lit(expr_path). But it works when constructing the patterns more carefully.

fixes #31574
2016-03-01derive: Emit only PartialOrd::partial_cmp for simple enumsUlrik Sverdrup-24/+35
Using the same logic as for `PartialEq`, when possible define only `partial_cmp` and leave `lt, le, gt, ge` to their default implementations. This works well for c-like enums.
2016-02-29derive: Skip PartialEq::ne for any zero-field enum or structUlrik Sverdrup-17/+15
Also detect unit structs and enums with zero field struct variants.
2016-02-29derive: Avoid emitting PartialEq::ne for c-like enumsUlrik Sverdrup-5/+28
`ne` is completely symmetrical with the method `eq`, and we can save rust code size and compilation time here if we only emit one of them when possible. One case where it's easy to recognize is when it's a C-like enum. Most other cases can not omit ne, because any value field may have a custom PartialEq implementation.
