2019-01-17Add signed num::NonZeroI* typesSimon Sapin-18/+32
Multiple people have asked for them, in https://github.com/rust-lang/rust/issues/49137. Given that the unsigned ones already exist, they are very easy to add and not an additional maintenance burden.

2019-01-17compiletest: Support opt-in Clang-based run-make tests.Michael Woerister-1/+101
Some cross-language run-make tests need a Clang compiler that matches the LLVM version of rustc. Since such a compiler usually isn't available these tests (marked with the "needs-matching-clang" directive) are ignored by default. For some CI jobs we do need these tests to run unconditionally though. In order to support this a --force-clang-based-tests flag is added to compiletest. If this flag is specified, compiletest will fail if it can't detect an appropriate version of Clang.

2019-01-17Use a faster early exit during region expansionBjörn Steinbrink-6/+8
Turns out that the equality check for regions is rather expensive, and the current early exit check works in such a way, that the comparison is even done twice. As we only really care about the case of equal scopes, we can perform a faster, more specialized check and move it up one level, so we can eventually skip the additional full comparison as well.

Prepare beta 1.33.0 This PR includes the usual changes for a new beta, and suppresses a few lints on libcore: those lints are false positives caused by an internal attribute (`rustc_layout_scalar_valid_range_start`) and only happen on stage0. r? @Mark-Simulacrum

2019-01-17Remove `hir::StmtKind::Decl`.Nicholas Nethercote-272/+150
It's a level of indirection that hurts far more than it helps. The code is simpler without it. (This commit cuts more than 120 lines of code.) In particular, this commit removes some unnecessary `Span`s within `DeclKind` that were always identical to those in the enclosing `Stmt`, and some unnecessary allocations via `P`.

It's overall faster to perform this extra check than to perform the query, even if the result is already in the query cache.
2019-01-16Auto merge of #57392 - Xanewok:always-calc-glob-map, r=petrochenkovbors-43/+13
Always calculate glob map but only for glob uses Previously calculating glob map was *opt-in*, however it did record node id -> ident use for every use directive. This aims to see if we can unconditionally calculate the glob map and not regress performance. Main motivation is to get rid of some of the moving pieces and simplify the compilation interface - this would allow us to entirely remove `CrateAnalysis`. Later, we could easily expose a relevant query, similar to the likes of `maybe_unused_trait_import` (so using precomputed data from the resolver, but which could be rewritten to be on-demand). r? @nikomatsakis Local perf run showed mostly noise (except `ctfe-stress-*`) but I'd appreciate if we could do a perf run run here and double-check that this won't regress performance.

2019-01-17Make `hir::Stmt` a separate struct.Nicholas Nethercote-87/+92
Benefits: - It lets us move the `NodeId` field out of every `hir::StmtKind` variant `NodeId` to a more sensible spot. - It eliminates sadness in `Stmt::fmt`. - It makes `hir::Stmt` match `ast::Stmt`.
2019-01-16[rustbuild] Rebuild std after changes to codegen backendsJosh Stone-0/+12
Use `clear_if_dirty` on std for backend changes, just as we do for changes to rustc itself, so new codegen is correctly applied to all later compiler stages. Fixes #48298.

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.
2019-01-16Fix memory leak in P::filter_mapTatsuyuki Ishi-0/+1
2019-01-16With this change, I am able to build and test cross-platform `rustc`Felix S. Klock II-5/+3
In particular, I can use the following in my `config.toml`: ``` [build] host = ["i686-unknown-linux-gnu", "x86_64-unknown-linux-gnu"] target = ["i686-unknown-linux-gnu", "x86_64-unknown-linux-gnu"] ``` Before this change, my attempt to run the test suite would fail because the error output differs depending on what your host and targets are. ---- To be concrete, here are the actual messages one can observe: ``` % ./build/x86_64-unknown-linux-gnu/stage1/bin/rustc ../src/test/ui/huge-enum.rs -Aunused --target=x86_64-unknown-linux-gnu error: the type `std::option::Option<[u32; 35184372088831]>` is too big for the current architecture error: aborting due to previous error % ./build/x86_64-unknown-linux-gnu/stage1/bin/rustc ../src/test/ui/huge-enum.rs -Aunused --target=i686-unknown-linux-gnu error: the type `std::option::Option<[u32; 536870911]>` is too big for the current architecture error: aborting due to previous error % ./build/i686-unknown-linux-gnu/stage1/bin/rustc ../src/test/ui/huge-enum.rs -Aunused --target=i686-unknown-linux-gnu error: the type `std::option::Option<[u32; 536870911]>` is too big for the current architecture error: aborting due to previous error % ./build/i686-unknown-linux-gnu/stage1/bin/rustc ../src/test/ui/huge-enum.rs -Aunused --target=x86_64-unknown-linux-gnu error: the type `[u32; 35184372088831]` is too big for the current architecture error: aborting due to previous error ``` To address these variations, I changed the test to be more aggressive in its normalization strategy. We cannot (and IMO should not) guarantee that `Option` will appear in the error output here. So I normalized both types `Option<[u32; N]>` and `[u32; N]` to just `TYPE`
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!

2019-01-16Use `Lit` rather than `P<Lit>` in `hir::ExprKind`.Nicholas Nethercote-2/+2
It's simpler and makes some benchmark run up to 1% faster. It also makes `hir::ExprKind` more like `ast::ExprKind` (which underwent the equivalent change in #55777).
