r? @brson cc @alexcrichton I still need to add error code explanation test with this, but I can't figure out a way to generate the `.md` files in order to test example source codes. Will fix #27328.

2016-02-10Auto merge of #31499 - kamalmarhubi:cfg-flag-invalid-cfgs, r=brsonbors-21/+60
A spec like `#[cfg(foo(bar))]` is not allowed as an attribute. This makes the same spec be rejected by the compiler if passed in as a `--cfg` argument. Fixes #31495

2016-02-08rustc: Implement a new `--print cfg` flagAlex Crichton-0/+19
This commit is an implementation of the new compiler flags required by [RFC 1361][rfc]. This specifically adds a new `cfg` option to the `--print` flag to the compiler. This new directive will print the defined `#[cfg]` directives by the compiler for the target in question. [rfc]: https://github.com/rust-lang/rfcs/blob/master/text/1361-cargo-cfg-dependencies.md
2016-02-08driver: Disallow predicates in --cfg specsKamal Marhubi-1/+16

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

2016-01-26Initial work towards abort-free compilationNick Cameron-246/+294
The goal is that the compiler will pass `Result`s around rather than using abort_if_errors. To preserve behaviour we currently abort at the top level. I've removed all other aborts from the driver, but haven't touched any of the nested aborts.

2016-01-16Auto merge of #30533 - nikomatsakis:fulfillment-tree, r=aturonbors-1/+1
This PR introduces an `ObligationForest` data structure that the fulfillment context can use to track what's going on, instead of the current flat vector. This enables a number of improvements: 1. transactional support, at least for pushing new obligations 2. remove the "errors will be reported" hack -- instead, we only add types to the global cache once their entire subtree has been proven safe. Before, we never knew when this point was reached because we didn't track the subtree. - this in turn allows us to limit coinductive reasoning to structural traits, which sidesteps #29859 3. keeping the backtrace should allow for an improved error message, where we give the user full context - we can also remove chained obligation causes This PR is not 100% complete. In particular: - [x] Currently, types that embed themselves like `struct Foo { f: Foo }` give an overflow when evaluating whether `Foo: Sized`. This is not a very user-friendly error message, and this is a common beginner error. I plan to special-case this scenario, I think. - [x] I should do some perf. measurements. (Update: 2% regression.) - [x] More tests targeting #29859 - [ ] The transactional support is not fully integrated, though that should be easy enough. - [ ] The error messages are not taking advantage of the backtrace. I'd certainly like to do 1 through 3 before landing, but 4 and 5 could come as separate PRs. r? @aturon // good way to learn more about this part of the trait system f? @arielb1 // already knows this part of the trait system :)

2016-01-16Auto merge of #30930 - oli-obk:fix/30887, r=arielb1bors-1/+6
this makes sure the checks run before typeck (which might use the constant or const function to calculate an array length) and gives prettier error messages in case of for loops and such (since they aren't expanded yet). fixes #30887 r? @pnkfelix

2016-01-15Address reviewer commentsNick Cameron-3/+3
[breaking-change] `OptLevel` variants are no longer `pub use`ed by rust::session::config. If you are using these variants, you must change your code to prefix the variant name with `OptLevel`.

2016-01-07Auto merge of #30317 - jseyfried:refactor_type_folder, r=nikomatsakisbors-1/+1
`TypeFoldable`s can currently be visited inefficiently with an identity folder that is run only for its side effects. This creates a more efficient visitor for `TypeFoldable`s and uses it to implement `RegionEscape` and `HasProjectionTypes`, fixing cleanup issue #20298. This is a pure refactoring.
