Unused variable suggestions apply on all patterns. Fixes #56685. This PR extends existing suggestions to prefix unused variable bindings in match arms with an underscore so that it applies to all patterns in a match arm. r? @estebank cc @alexcrichton (since you filed the issue)

2019-01-28Auto merge of #57442 - oli-obk:lazy_const, r=RalfJungbors-80/+71
Simplify `ConstValue::ScalarPair` While looking at #57432 I realized that some of our types for representing constants are very big. This reduces `LazyConst` to 3/4th of its original size and simplifies some code around slices at the same time. r? @RalfJung
2019-01-27Auto merge of #56932 - clarcharr:iter_refactor, r=Centrilbors-3862/+4032
Refactor core::iter module A while back, I refactored `core::ops` in #42523 because the module had become a giant mess and was difficult to modify. Now, I'm doing the same with the `core::iter` module. Like the `core::ops` refactor, things have been split up into multiple commits to make rebasing easier, and so that you can follow changes. Although the diffs are hard to decipher, the only actual code changes I've made in the first few commits are to modify exports and imports. I save all of the actual code refactoring, e.g. modifying what methods are called, for the end.

Fix some minor warnings Since apparently RLS works when initialized in the root repository (:tada:) I decided to fix some of the issues it caught. There are a lot of unused attribute warnings left on `rustc_on_unimplemented` and `rustc_layout_scalar_valid_range_start` but I imagine we can't do much about it due to 2-stage compilation?

2019-01-26Workaround presence of LLVM library in stage0/libMark Rousskov-13/+55
This commit works around the newly-introduced LLVM shared library. This is needed such that llvm-config run from librustc_llvm's build script can correctly locate it's own LLVM, not the one in stage0/lib. The LLVM build system uses the DT_RUNPATH/RUNPATH header within the llvm-config binary, which we want to use, but because Cargo always adds the host compiler's "libdir" (stage0/lib in our case) to the dynamic linker's search path, we weren't properly finding the freshly-built LLVM in llvm/lib. By restoring the environment variable setting the search path to what bootstrap sees, the problem is resolved and librustc_llvm correctly links and finds the appropriate LLVM. Several run-make-fulldeps tests are also updated with similar handling.

2019-01-26Auto merge of #57425 - alexcrichton:stabilize-atomics, r=sfacklerbors-55/+96
std: Stabilize fixed-width integer atomics This commit stabilizes the `Atomic{I,U}{8,16,32,64}` APIs in the `std::sync::atomic` and `core::sync::atomic` modules. Proposed in #56753 and tracked in #32976 this feature has been unstable for quite some time and is hopefully ready to go over the finish line now! The API is being stabilized as-is. The API of `AtomicU8` and friends mirrors that of `AtomicUsize`. A list of changes made here are: * A portability documentation section has been added to describe the current state of affairs. * Emulation of smaller-size atomics with larger-size atomics has been documented. * As an added bonus, `ATOMIC_*_INIT` is now scheduled for deprecation across the board in 1.34.0 now that `const` functions can be invoked in statics. Note that the 128-bit atomic types are omitted from this stabilization explicitly. They have far less platform support than the other atomic types, and will likely require further discussion about their best location. Closes #32976 Closes #56753
2019-01-26Auto merge of #55641 - nagisa:optimize-attr, r=pnkfelixbors-128/+448
Implement optimize(size) and optimize(speed) attributes This PR implements both `optimize(size)` and `optimize(speed)` attributes. While the functionality itself works fine now, this PR is not yet complete: the code might be messy in places and, most importantly, the compiletest must be improved with functionality to run tests with custom optimization levels. Otherwise the new attribute cannot be tested properly. Oh, and not all of the RFC is implemented – attribute propagation is not implemented for example. # TODO * [x] Improve compiletest so that tests can be written; * [x] Assign a proper error number (E9999 currently, no idea how to allocate a number properly); * [ ] Perhaps reduce the duplication in LLVM attribute assignment code…
