2016-09-06Auto merge of #36252 - joshtriplett:union-field-never-used, r=sanxiynbors-6/+32
Fix "field is never used" warning to take unions into account When compiling code containing a union with an unused field, rustc says "struct field is never used". Rather than saying "struct or union", or adding logic to determine the type of the item, just change the message to "field is never used", dropping the "struct". Update tests accordingly.

2016-09-06Auto merge of #36025 - michaelwoerister:incr-comp-hash-spans, r=nikomatsakisbors-145/+843
incr. comp.: Take spans into account for ICH This PR makes the ICH (incr. comp. hash) take spans into account when debuginfo is enabled. A side-effect of this is that the SVH (which is based on the ICHs of all items in the crate) becomes sensitive to the tiniest change in a code base if debuginfo is enabled. Since we are not trying to model ABI compatibility via the SVH anymore (this is done via the crate disambiguator now), this should be not be a problem. Fixes #33888. Fixes #32753.

2016-09-05Auto merge of #36200 - mattico:fix-llvm-linkage, r=arielb1bors-66/+180
Fix incorrect LLVM Linkage enum Followup of #33994 to actually work. The `Linkage` enum in librustc_llvm got out of sync with the version in LLVM and it caused two variants of the `#[linkage=""]` attribute to break. This adds the functions `LLVMRustGetLinkage` and `LLVMRustSetLinkage` which convert between the Rust Linkage enum and the LLVM one, which should stop this from breaking every time LLVM changes it. Possible remaining concerns: 1. There could be a codegen test to make sure that the attributes are applied correctly (I don't know how to do this). 2. ~~The test does not exercise the `appending` linkage. I can't figure out how to make a global static raw pointer to an array. This might not even be possible? If not we should probably remove appending linkage as its unusable in rust.~~ Appending linkage is not 'emittable' anyway. 3. The test only runs on Linux. Fixes #33992 r? @alexcrichton
