2019-01-25Rebase to the llvm-project monorepoJosh Stone-1/+4
The new git submodule src/llvm-project is a monorepo replacing src/llvm and src/tools/{clang,lld,lldb}. This also serves as a rebase for these projects to the new 8.x branch from trunk. The src/llvm-emscripten fork is unchanged for now.

[NLL] Clean up handling of type annotations * Renames (Canonical)?UserTypeAnnotation -> (Canonical)?UserType so that the name CanonicalUserTypeAnnotation is free. * Keep the inferred type associated to user type annotations in the MIR, so that it can be compared against the annotated type, even when the annotated expression gets removed from the MIR. (#54943) * Use the inferred type to allow infallible handling of user type projections (#57531) * Uses revisions for the tests in #56993 * Check the types of `Unevaluated` constants with no annotations (#46702) * Some drive-by cleanup Closes #46702 Closes #54943 Closes #57531 Closes #57731 cc #56993 leaving this open to track the underlying issue: we are not running tests with full NLL enabled on CI at the moment r? @nikomatsakis

This commit combines the move lifetime and move type suggestions so that when rustfix applies them they don't conflict with each other.

This commit extends existing suggestions to move lifetimes before types in generic arguments to also suggest moving types behind associated type bindings.

2019-01-24Rollup merge of #57846 - QuietMisdreavus:proc-macro-links, r=GuillaumeGomezMazdak Farrokhzad-0/+5
rustdoc: fix ICE from loading proc-macro stubs Fixes https://github.com/rust-lang/rust/issues/55399 When trying to resolve a macro, rustdoc first tries to load it from the resolver to see whether it's a Macros 2.0 macro, so it can return that Def before looking for any other kind of macro. However, this becomes a problem when you try to load proc-macros: since you can't use a proc-macro inside its own crate, this lookup also fails when attempting to link to it. However, we have a hint that this lookup will fail: Macros which are actually `ProcMacroStub`s will fail the lookup, so we can use that information to skip loading the macro. Rustdoc will then happily check `resolve.all_macros`, which will return a usable Def that we can link to.

2019-01-24Auto merge of #51285 - Mark-Simulacrum:remove-quote_apis, r=Manishearthbors-1242/+34
Remove quote_*! macros This deletes a considerable amount of test cases, some of which we may want to keep. I'm not entirely certain what the primary intent of many of them was; if we should keep them I can attempt to edit each case to continue compiling without the quote_*! macros involved. Fixes #46849. Fixes #12265. Fixes #12266. Fixes #26994. r? @Manishearth

2019-01-24Auto merge of #57269 - gnzlbg:simd_bitmask, r=rkruppebors-0/+241
Add intrinsic to create an integer bitmask from a vector mask This PR adds a new simd intrinsic: `simd_bitmask(vector) -> unsigned integer` that creates an integer bitmask from a vector mask by extracting one bit of each vector lane. This is required to implement: https://github.com/rust-lang-nursery/packed_simd/issues/166 . EDIT: the reason we need an intrinsics for this is that we have to truncate the vector lanes to an `<i1 x N>` vector, and then bitcast that to an `iN` integer (while making sure that we only materialize `i8`, ... , `i64` - that is, no `i1`, `i2`, `i4`, types), and we can't do any of that in a Rust library. r? @rkruppe
