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.

2016-01-26Auto merge of #31120 - alexcrichton:attribute-deny-warnings, r=brsonbors-2/+2
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

2015-12-19Auto merge of #30184 - petrochenkov:ascr, r=nikomatsakisbors-5/+24
This PR is a rebase of the original PR by @eddyb https://github.com/rust-lang/rust/pull/21836 with some unrebasable parts manually reapplied, feature gate added + type equality restriction added as described below. This implementation is partial because the type equality restriction is applied to all type ascription expressions and not only those in lvalue contexts. Thus, all difficulties with detection of these contexts and translation of coercions having effect in runtime are avoided. So, you can't write things with coercions like `let slice = &[1, 2, 3]: &[u8];`. It obviously makes type ascription less useful than it should be, but it's still much more useful than not having type ascription at all. In particular, things like `let v = something.iter().collect(): Vec<_>;` and `let u = t.into(): U;` work as expected and I'm pretty happy with these improvements alone.
