rustc: Add a `#[wasm_custom_section]` attribute This commit is an implementation of adding custom sections to wasm artifacts in rustc. The intention here is to expose the ability of the wasm binary format to contain custom sections with arbitrary user-defined data. Currently neither our version of LLVM nor LLD supports this so the implementation is currently custom to rustc itself. The implementation here is to attach a `#[wasm_custom_section = "foo"]` attribute to any `const` which has a type like `[u8; N]`. Other types of constants aren't supported yet but may be added one day! This should hopefully be enough to get off the ground with some custom section support. The current semantics are that any constant tagged with `#[wasm_custom_section]` section will be appended to the corresponding section in the final output wasm artifact (and this affects dependencies linked in as well, not just the final crate). This means that whatever is interpreting the contents must be able to interpret binary-concatenated sections (or each constant needs to be in its own custom section). To test this change the existing `run-make` test suite was moved to a `run-make-fulldeps` folder and a new `run-make` test suite was added which applies to all targets by default. This test suite currently only has one test which only runs for the wasm target (using a node.js script to use `WebAssembly` in JS to parse the wasm output). 2018-03-09 11:26:15 -06:00
Upgrade Emscripten targets to use upstream LLVM backend - Compatible with Emscripten 1.38.46-upstream or later upstream. - Refactors the Emscripten target spec to share code with other wasm targets. - Replaces the old incorrect wasm32 C call ABI with the correct one, preserving the old one as wasm32_bindgen_compat for wasm-bindgen compatibility. - Updates the varargs ABI used by Emscripten and deletes the old one. - Removes the obsolete wasm32-experimental-emscripten target. - Uses EMCC_CFLAGS on CI to avoid the timeout problems with #63649. 2019-08-17 00:08:01 -05:00			`# only-wasm32-bare`
use ignore directives for run-make tests This makes the tests easier to read, and makes it possible to tell which tests aren't being run on the host platform. Fixes #56704. 2019-01-06 15:27:57 -06:00
