Alex Crichton 5f006cebfc rustc: Tweak #[target_feature] syntax 
This is an implementation of the `#[target_feature]` syntax-related changes of
[RFC 2045][rfc]. Notably two changes have been implemented:

* The new syntax is `#[target_feature(enable = "..")]` instead of
  `#[target_feature = "+.."]`. The `enable` key is necessary instead of the `+`
  to indicate that a feature is being enabled, and a sub-list is used for
  possible expansion in the future. Additionally within this syntax the feature
  names being enabled are now whitelisted against a known set of target feature
  names that we know about.

* The `#[target_feature]` attribute can only be applied to unsafe functions. It
  was decided in the RFC that invoking an instruction possibly not defined for
  the current processor is undefined behavior, so to enable this feature for now
  it requires an `unsafe` intervention.

README.md

NB: This crate is part of the Rust compiler. For an overview of the compiler as a whole, see the README.md file found in librustc.

The trans crate contains the code to convert from MIR into LLVM IR, and then from LLVM IR into machine code. In general it contains code that runs towards the end of the compilation process.
