2019-01-16Auto merge of #57321 - petrochenkov:atokens, r=nikomatsakisbors-1625/+1398
Implement basic input validation for built-in attributes Correct top-level shape (`#[attr]` vs `#[attr(...)]` vs `#[attr = ...]`) is enforced for built-in attributes, built-in attributes must also fit into the "meta-item" syntax (aka the "classic attribute syntax"). For some subset of attributes (found by crater run), errors are lowered to deprecation warnings. NOTE: This PR previously included https://github.com/rust-lang/rust/pull/57367 as well.
2019-01-16Auto merge of #57416 - alexcrichton:remove-platform-intrinsics, r=nagisabors-15986/+4
rustc: Remove platform intrinsics crate This was originally attempted in #57048 but it was realized that we could fully remove the crate via the `"unadjusted"` ABI on intrinsics. This means that all intrinsics in stdsimd are implemented directly against LLVM rather than using the abstraction layer provided here. That ends up meaning that this crate is no longer used at all. This crate developed long ago to implement the SIMD intrinsics, but we didn't end up using it in the long run. In that case let's remove it!

Simplify 'product' factorial example This simplifies the [`factorial(n: 32)`](https://doc.rust-lang.org/std/iter/trait.Iterator.html#examples-46) implementation as example for the `Iterator::product()` function. It currently uses unnecessary additional complexity. Although very minimal, I do not want to include it in some other irrelevant PR.

2019-01-15Rollup merge of #57579 - stjepang:once-with, r=SimonSapinMazdak Farrokhzad-0/+135
Add core::iter::once_with() Functions `iter::once()` and `iter::repeat()` construct iterators from values. The latter has the lazy variant `iter::repeat_with()`, but the former doesn't. This PR therefore adds `iter::once_with()`. Another way to think of `iter::once_with()` is that it's a function that converts `FnOnce() -> T` into `Iterator<Item = T>`. If this seems like a reasonable addition, I'll open a tracking issue and update the `#[feature(...)]` attributes.

forbid manually impl'ing one of an object type's marker traits This shouldn't break compatibility for crates that do not use `feature(optin_builtin_traits)`, because as the test shows, it is only possible to impl a marker trait for a trait object in the crate the marker trait is defined in, which must define `feature(optin_builtin_traits)`. Fixes #56934. r? @nikomatsakis
2019-01-15Rollup merge of #56044 - matthewjasper:function-param-drop-order, r=cramertjMazdak Farrokhzad-7/+75
Drop partially bound function parameters in the expected order Given the function ```rust fn foo((_x, _): (LogDrop, LogDrop), (_, _y): (LogDrop, LogDrop)) {} ``` Prior to 1.12.0 we dropped both `_x` and `_y` before the rest of their respective parameters, since then we dropped `_x` and `_y` after. The original order appears to be the correct order, as the value created later is dropped first, so we revert to that order and add a test for it. While this is technically a breaking change, I can't work out how anyone could be relying on this without making their code very brittle. If this is considered to be too likely to break real world code then I can revert the change and change the test to check for the current order.

VardhanThigle:Vardhan/x86_64-fortanix-unknown-sgx-tier2_support, r=alexcrichton Upgrade x86_64-fortanix-unknown-sgx platform support to tier 2 ## Overview 1. This PR upgrades x86_64-fortanix-unknown-sgx platform support to tier 2 (std only) by setting up build automation for this target. 1. For supporting unwinding, this target needs to link to a port of LLVM's libunwind (more details could be found in #56979), which will be distributed along with the Rust binaries (similar to the extra musl objects) ### Building and copying libunwind: We have added a new build script (`build-x86_64-fortanix-unknown-sgx-toolchain.sh`) that will run while the container is built. This will build `libunwind.a` from git source. While the container is built, the persistent volumes where obj/ gets created aren't yet mapped. As a workaround, we copy the built `libunwind.a` to `obj/build/x86_64-unknown-linux-gnu/stage2/lib/rustlib/x86_64-fortanix-unknown-sgx/lib/` after x.py runs. If any reviewer knows of a better solution, please do tell. r? @Mark-Simulacrum

Querify local `plugin_registrar_fn` and `proc_macro_decls_static` Instead of calculating them as part of the `Session`, we do that in the query system. It's also nice that these queries are already defined for external crates - here, we provide the queries for the local crate. r? @nikomatsakis
2019-01-14Rollup merge of #57540 - estebank:eval-more, r=petrochenkovMazdak Farrokhzad-141/+344
Modify some parser diagnostics to continue evaluating beyond the parser Continue evaluating further errors after parser errors on: - trailing type argument attribute - lifetime in incorrect location - incorrect binary literal - missing `for` in `impl Trait for Foo` - type argument in `where` clause - incorrect float literal - incorrect `..` in pattern - associated types - incorrect discriminator value variant error and others. All of these were found by making `continue-parse-after-error` `true` by default to identify errors that would need few changes. There are now only a handful of errors that have any change with `continue-parse-after-error` enabled. These changes make it so `rust` _won't_ stop evaluation after finishing parsing, enabling type checking errors to be displayed on the existing code without having to fix the parse errors. Each commit has an individual diagnostic change with their corresponding tests. CC #48724.

Fix poor worst case performance of set intersection Specifically, intersection of asymmetrically sized sets when the large set is on the left. See also the [latest answer on stackoverflow](https://stackoverflow.com/questions/35439376/python-set-intersection-is-faster-then-rust-hashset-intersection). Also applied to the union member, where the effect is much less but still measurable. Formatted the changed code only, does not increase the error count reported by tidy check, and tried to adhere to the spirit of the unit tests.

r=joshtriplett,Centril Stabilize cfg_target_vendor This stabilizes the use of `cfg(target_vendor = "...")` and removes the corresponding `cfg_target_vendor` feature. Other unstable cfgs remain behind their existing feature gates. This functionality was added back in 2015 in #28612 to complete the coverage of target tuples (`<arch><sub>-<vendor>-<os>-<env>`). [RFC 131](https://github.com/rust-lang/rfcs/blob/master/text/0131-target-specification.md) governs the target specification, not including `target_vendor` seems to have just been an oversight. `target_os`, `target_family`, and `target_arch` are stable as of 1.0.0. `target_env` was also not mentioned in RFC 131, was added in #24777, never behind a feature_gate, and insta-stable at 1.1.0. The functionality is tested in [test/run-pass/cfg/cfg-target-vendor.rs](https://github.com/rust-lang/rust/blob/master/src/test/run-pass/cfg/cfg-target-vendor.rs). Closes #29718
