2019-10-29Rollup merge of #65832 - tlively:emscripten-exception-handling, r=alexcrichtonTyler Mandry-1/+1
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. r? @alexcrichton
2019-10-29Rollup merge of #65809 - roblabla:eficall-abi, r=nagisaMazdak Farrokhzad-70/+141
Add new EFIAPI ABI Fixes #54527 Adds a new ABI, "efiapi", which reflects the calling convention as specified by [the current spec UEFI spec](https://uefi.org/sites/default/files/resources/UEFI%20Spec%202_7_A%20Sept%206.pdf#G6.999903). When compiling for x86_64, we should select the `win64` ABI, while on all other architectures (Itanium, x86, ARM and ARM64 and RISC-V), we should select the `C` ABI. Currently, this is done by just turning it into the C ABI everywhere except on x86_64, where it's turned into the win64 ABI. Should we prevent this ABI from being used on unsupported architectures, and if so, how would this be done?

2019-10-25Add proper tracking issue for EFIAPIroblabla-7/+7
2019-10-25Add new EFIAPI ABIroblabla-70/+141
Adds a new ABI for the EFIAPI calls. This ABI should reflect the latest version of the UEFI specification at the time of commit (UEFI spec 2.8, URL below). The specification says that for x86_64, we should follow the win64 ABI, while on all other supported platforms (ia32, itanium, arm, arm64 and risc-v), we should follow the C ABI. To simplify the implementation, we will simply follow the C ABI on all platforms except x86_64, even those technically unsupported by the UEFI specification. https://uefi.org/sites/default/files/resources/UEFI_Spec_2_8_final.pdf

2019-10-21Rollup merge of #62330 - SimonSapin:no-drop-in-union-fields, r=RalfJungMazdak Farrokhzad-7/+32
Change untagged_unions to not allow union fields with drop This is a rebase of #56440, massaged to solve merge conflicts and make the test suite pass. Change untagged_unions to not allow union fields with drop Union fields may now never have a type with attached destructor. This for example allows unions to use arbitrary field types only by wrapping them in `ManuallyDrop` (or similar). The stable rule remains, that union fields must be `Copy`. We use the new rule for the `untagged_union` feature. Tracking issue: https://github.com/rust-lang/rust/issues/55149

2019-10-17Plugins deprecation: don’t suggest simply removing the attributeSimon Sapin-4/+4
Building Servo with a recent Nightly produces: ```rust warning: use of deprecated attribute `plugin`: compiler plugins are deprecated. See https://github.com/rust-lang/rust/issues/29597 --> components/script/lib.rs:14:1 | 14 | #![plugin(script_plugins)] | ^^^^^^^^^^^^^^^^^^^^^^^^^^ help: remove this attribute | = note: `#[warn(deprecated)]` on by default ``` First, linking to https://github.com/rust-lang/rust/issues/29597 is not ideal since there is pretty much no discussion there of the deprecation and what can be used instead. This PR changes the link to the deprecation PR which does have more discussion. Second, the “remove this attribute” suggestion is rather unhelpful. Just because a feature is deprecated doesn’t mean that simply removing its use without a replacement is acceptable. In the case of custom lint, there is no replacement available. Prefixing a message with “help:” when telling users that they’re screwed honestly feels disrespectful. This PR also changes the message to be more factual.

2019-10-16Upgrade Emscripten targets to use upstream LLVM backendThomas Lively-0/+1
- 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.

The stable rule remains, that union fields must be Copy. We use the new rule for the `untagged_union` feature. See RFC 2514. Note for ui tests: We can't test move out through Box's deref-move since we can't have a Box in a union anymore.
