2019-11-06Rollup merge of #66054 - petrochenkov:delspan, r=estebankMazdak Farrokhzad-17/+7
syntax: Avoid span arithmetic for delimiter tokens The +/-1 logic is from the time where the whole group had a single span and the delimiter spans had to be calculated from it. Now the delimiters have their own spans which are constructed by lexer or proc macro API and can be used directly. If those spans are not perfect, then it should be fixed by tweaking the corresponding lexer logic rather than by trying to add or substract `1` from the span boundaries. Fixes https://github.com/rust-lang/rust/issues/62524 r? @estebank

2019-11-04Auto merge of #65838 - estebank:resilient-recovery, r=Centrilbors-48/+96
Reduce amount of errors given unclosed delimiter When in a file with a non-terminated item, catch the error and consume the block instead of trying to recover it on a more granular way in order to reduce the amount of unrelated errors that would be fixed after adding the missing closing brace. Also point out the possible location of the missing closing brace. Fix #63690.

2019-11-02Auto merge of #66004 - eddyb:revert-early-gate, r=petrochenkovbors-2/+110
Partially revert the early feature-gatings added in #65742. The intent here is to address #65860 ASAP (in time for beta, ideally), while leaving as much of #65742 around as possible, to make it easier to re-enable later. Therefore, I've only kept the parts of the revert that re-add the old (i.e. non-early) feature-gating checks that were removed in #65742, and the test reverts. I've disabled the new early feature-gating checks from #65742 entirely for now, but it would be easy to put them behind a `-Z` flag, or turn them into warnings, which would allow us to keep tests for both the early and late versions of the checks - assuming that's desirable. cc @nikomatsakis @Mark-Simulacrum @Centril

2019-10-29Rollup merge of #65809 - roblabla:eficall-abi, r=nagisaMazdak Farrokhzad-0/+7
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?
2019-10-29Rollup merge of #65294 - varkor:lint-inline-prototype, r=matthewjasperMazdak Farrokhzad-1/+1
Lint ignored `#[inline]` on function prototypes Fixes https://github.com/rust-lang/rust/issues/51280. - Adds a `unused_attribute` lint for `#[inline]` on function prototypes. - As a consequence, foreign items, impl items and trait items now have their attributes checked, which could cause some code to no longer compile (it was previously erroneously ignored).

2019-10-28Auto merge of #65188 - matthewjasper:stabilize-const-constructor, r=Centrilbors-3/+2
Stabilize `const_constructor` # Stabilization proposal I propose that we stabilize `#![feature(const_constructor)]`. Tracking issue: https://github.com/rust-lang/rust/issues/61456 Version target: 1.40 (2019-11-05 => beta, 2019-12-19 => stable). ## What is stabilized ### User guide Tuple struct and tuple variant constructors are now considered to be constant functions. As such a call expression where the callee has a tuple struct or variant constructor "function item" type can be called: ```rust const fn make_options() { // These already work because they are special cased: Some(0); (Option::Some)(1); // These also work now: let f = Option::Some; f(2); {Option::Some}(3); <Option<_>>::Some(5); } ``` ### Motivation Consistency with other `const fn`. Consistency between syntactic path forms. This should also ensure that constructors implement `const Fn` traits and can be coerced to `const fn` function pointers, if they are introduced. ## Tests * [ui/consts/const_constructor/const-construct-call.rs](https://github.com/rust-lang/rust/blob/0d75ab2293a106eb674ac01860910cfc1580837e/src/test/ui/consts/const_constructor/const-construct-call.rs) - Tests various syntactic forms, use in both `const fn` and `const` items, and constructors in both the current and extern crates. * [ui/consts/const_constructor/const_constructor_qpath.rs](https://github.com/rust-lang/rust/blob/1850dfcdabf8258a1f023f26c2c59e96b869dd95/src/test/ui/consts/const_constructor/const_constructor_qpath.rs) - Tests that type qualified paths to enum variants are also considered to be `const fn`.(#64247) r? @oli-obk Closes #61456 Closes #64247

libsyntax: Enhance documentation of the AST module This PR enhances documentation state to the `libsyntax/ast.rs` (as initiative caused by [rustc-guide#474](https://github.com/rust-lang/rustc-guide/issues/474)), by adding: - Module documentation. - Doc-comments (and a bit of usual comments) in non-obvious (as for me) places. - Minor style fixes to improve module readability.

2019-10-25Add new EFIAPI ABIroblabla-0/+7
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
