2015-10-06Add RFC 1238's `unsafe_destructor_blind_to_params` (UGEH) where needed.Felix S. Klock II-4/+4
I needed it in `RawVec`, `Vec`, and `TypedArena` for `rustc` to bootstrap; but of course that alone was not sufficient for `make check`. Later I added `unsafe_destructor_blind_to_params` to collections, in particular `LinkedList` and `RawTable` (the backing representation for `HashMap` and `HashSet`), to get the regression tests exercising cyclic structure from PR #27185 building. ---- Note that the feature is `dropck_parametricity` (which is not the same as the attribute's name). We will almost certainly vary our strategy here in the future, so it makes some sense to have a not-as-ugly name for the feature gate. (The attribute name was deliberately selected to be ugly looking.)
2015-10-06Non-parametric dropck; instead trust an unsafe attribute (RFC 1238).Felix S. Klock II-0/+9
Implement cannot-assume-parametricity (CAP) from RFC 1238, and add the UGEH attribute. ---- Note that we check for the attribute attached to the dtor method, not the Drop impl. (This is just to match the specification of RFC and the tests; I am not wedded to this approach.)

2015-09-26Auto merge of #28642 - petrochenkov:name3, r=nrcbors-222/+170
This PR removes random remaining `Ident`s outside of libsyntax and performs general cleanup In particular, interfaces of `Name` and `Ident` are tidied up, `Name`s and `Ident`s being small `Copy` aggregates are always passed to functions by value, and `Ident`s are never used as keys in maps, because `Ident` comparisons are tricky. Although this PR closes https://github.com/rust-lang/rust/issues/6993 there's still work related to it: - `Name` can be made `NonZero` to compress numerous `Option<Name>`s and `Option<Ident>`s but it requires const unsafe functions. - Implementation of `PartialEq` on `Ident` should be eliminated and replaced with explicit hygienic, non-hygienic or member-wise comparisons. - Finally, large parts of AST can potentially be converted to `Name`s in the same way as HIR to clearly separate identifiers used in hygienic and non-hygienic contexts. r? @nrc
2015-09-26Auto merge of #28612 - gandro:targetvendor, r=alexcrichtonbors-0/+7
This adds a new target property, `target_vendor`. It is to be be used as a matcher for conditional compilation. The vendor is part of the [autoconf target triple](http://llvm.org/docs/doxygen/html/classllvm_1_1Triple.html#details): `<arch><sub>-<vendor>-<os>-<env>`. `arch`, `target_os` and `target_env` are already supported by Rust. This change was suggested in PR #28593. It enables conditional compilation based on the vendor. This is needed for the rumprun target, which needs to match against both, target_os and target_vendor. The default value for `target_vendor` is "unknown", "apple" and "pc" are other common values. Matching against the `target_vendor` is introduced behind the feature gate `#![feature(cfg_target_vendor)]`. This is the first time I messed around with rustc internals. I just added the my code where I found the existing `target_*` variables, hopefully I haven't missed anything. Please review with care. :) r? @alexcrichton

2015-09-24rustc: Add target_vendor for target triplesSebastian Wicki-0/+7
This adds a new target property, `target_vendor` which can be used as a matcher for conditional compilation. The vendor is part of the autoconf target triple: <arch><sub>-<vendor>-<os>-<env> The default value for `target_vendor` is "unknown". Matching against the `target_vendor` with `#[cfg]` is currently feature gated as `cfg_target_vendor`.
