rustc: Allow using `clang` for wasm32 targets This commit adds support code for using `clang` directly to link the wasm32-unknown-unknown target. Currently the target is only really configured to link with LLD directly, but this ensures that `clang` can be configured as well. While not immediately useful in the near term it's likely that more wasm32 targets will pop up over time with Clang's new native support for WebAssembly in the 8.0.0 release. Getting support into rustc early should make it easier to experiment with these targets and try out various changes here and there.

rustc: Update linker flavor inference from filename This commit fixes what is believed to be a preexisting bug in the linker flavor inference and additionally adds a new features. Previously if the linker didn't end in `exe` the entire file name was compared to infer the linker's flavor. This commit fixes the code to instead unconditionally inspect `file_stem()` which is the relevant part we're looking at to figure out what the linker flavor is. Additionally this commit now also adds recognition of `clang` and clang wrappers that end in `-clang` (which look like gcc wrappers). This should allow clang-specific wrappers to get correctly inferred to the `Gcc` linker flavor rather than the default linker flavor configured for a target.
2019-03-28Rollup merge of #59441 - TheGoddessInari:natvis, r=alexcrichtonMazdak Farrokhzad-12/+0
Remove the block on natvis for lld-link. Since #56642 bumped minimum LLVM version to 6.0.0, Rust should be able to honor or ignore Windows natvis support with lld-link. It looks like https://github.com/llvm-mirror/lld/commit/9133ca57b was in LLVM 7.0, while https://github.com/llvm-mirror/lld/commit/27b9c4285 made it into 6.0, at least if the release branches are anything to go by. Fixes #59383.

2019-03-08Rollup merge of #58926 - gabi-250:tcx-lifetimes, r=petrochenkovPietro Albini-2/+2
Make the lifetime parameters of tcx consistent. I have implemented `codegen_allocator` for my backend, but I've had to make a small change to its signature in `ExtraBackendMethods`. I wonder if this change is justified, or if it is too specific to my use case to be useful to anyone else. `write_metadata` and `codegen_allocator` are both called from `codegen_crate` (in `librustc_codegen_ssa/base.rs`), and they both receive the same `tcx` as an argument: https://github.com/rust-lang/rust/blob/c196097e588b05e86b5ce6de992b2a6e6a7027bd/src/librustc_codegen_ssa/base.rs#L555-L557 and: https://github.com/rust-lang/rust/blob/c196097e588b05e86b5ce6de992b2a6e6a7027bd/src/librustc_codegen_ssa/base.rs#L640-L642 However, `codegen_allocator` accepts a `TyCtxt` with any lifetime parameters (`tcx: TyCtxt<'_, '_, '_>`), while `write_metadata` requires that the `tcx` argument is of type `TyCtxt<'b, 'gcx, 'gcx>`. In my implementation, I've found that it's necessary for `tcx` in `codegen_allocator` to also have the `<'b, 'gcx, 'gcx>` lifetime parameters. Have I misunderstood the purpose of the parameters of `TyCtxt`? I've read [here](https://rust-lang.github.io/rustc-guide/ty.html) that the last two parameters only need to be distinct if the function needs to be used during type inference, but I don't think that is the case here.

rustc: Update LLVM, remove dead wasm code This commit updates the LLVM branch to the rebased version of the upstream release/8.x branch. This includes a wasm patch which means that the `rewrite_imports` pass in rustc is no longer needed (yay!) and we can instead rely on `wasm-import-module`, an attribute we're already emitting, to take care of all the work.
2019-02-27Rename variadic to c_variadicDan Robertson-4/+4
Function signatures with the `variadic` member set are actually C-variadic functions. Make this a little more explicit by renaming the `variadic` boolean value, `c_variadic`.
