2019-10-08Update LLVM for Emscripten exception handling supportThomas Lively-0/+0
Updates LLVM to pick up the cherry-picked support for correctly handling exception handling with aggregates passed by value. This will be necessary to continue to support Emscripten's exception handling once we switch using Emscripten's LLVM backend. See #63649.

2019-07-25std: Use native `#[thread_local]` TLS on wasmAlex Crichton-0/+0
This commit moves `thread_local!` on WebAssembly targets to using the `#[thread_local]` attribute in LLVM. This was recently implemented upstream and is [in the process of being documented][dox]. This change only takes affect if modules are compiled with `+atomics` which is currently unstable and a pretty esoteric method of compiling wasm artifacts. This "new power" of the wasm toolchain means that the old `wasm-bindgen-threads` feature of the standard library can be removed since it should now be possible to create a fully functioning threaded wasm module without intrusively dealing with libstd symbols or intrinsics. Yay! [dox]: https://github.com/WebAssembly/tool-conventions/pull/116

2019-05-22Bump compiler-builtins to 0.1.15Alex Crichton-0/+0
This commit bumps the `compiler-builtins` dependency to 0.1.15 which expects to have the source for `compiler-rt` provided externally if the `c` feature is enabled. This then plumbs through the necessary support in the build system to ensure that if the `llvm-project` directory is checked out and present that we enable the `c` feature of `compiler-builtins` and compile in all the C intrinsics.

2019-05-14Update LLVM to fix assertion when compiling to wasmAlex Crichton-0/+0

2019-04-03Support using LLVM's libunwind as the unwinder implementationPetr Hosek-0/+0
This avoids the dependency on host libraries such as libgcc_s which may be undesirable in some deployment environments where these aren't available.

2019-02-26rustc: Update LLVM, remove dead wasm codeAlex Crichton-0/+0
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.

2019-01-25Rebase to the llvm-project monorepoJosh Stone-0/+0
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.
