Re-enable Emscripten's exception handling support Passes LLVM codegen and Emscripten link-time flags for exception handling if and only if the panic strategy is `unwind`. Sets the default panic strategy for Emscripten targets to `unwind`. Re-enables tests that depend on unwinding support for Emscripten, including `should_panic` tests. 2019-10-18 14:47:54 -07:00			`// ignore-wasm32-bare compiled with panic=abort by default`
ci: Start running wasm32 tests on Travis This commit allocates a builder to running wasm32 tests on Travis. Not all test suites pass right now so this is starting out with just the run-pass and the libcore test suites. This'll hopefully give us a pretty broad set of coverage for integration in rustc itself as well as a somewhat broad coverage of the llvm backend itself through integration/unit tests. 2017-11-26 10:39:16 -08:00
