2019-12-22Rollup merge of #66877 - skinny121:const-eval-entry-points, r=oli-obkMazdak Farrokhzad-23/+10
Add simpler entry points to const eval for common usages. I found the `tcx.const_eval` API to be complex/awkward to work with, because of the inherent complexity from all of the different situations it is called from. Though it mainly used in one of the following ways: - Evaluates the value of a constant without any substitutions, e.g. evaluating a static, discriminant, etc. - Evaluates the value of a resolved instance of a constant. this happens when evaluating unevaluated constants or normalising trait constants. - Evaluates a promoted constant. This PR adds three new functions `const_eval_mono`, `const_eval_resolve`, and `const_eval_promoted` to `TyCtxt`, which each cater to one of the three ways `tcx.const_eval` is normally used.

2019-12-20Rollup merge of #64588 - matthewjasper:mir-address-of, r=oli-obkMazdak Farrokhzad-21/+41
Add a raw "address of" operator * Parse and feature gate `&raw [const | mut] expr` (feature gate name is `raw_address_of`) * Add `mir::Rvalue::AddressOf` * Use the new `Rvalue` for: * the new syntax * reference to pointer casts * drop shims for slices and arrays * Stop using `mir::Rvalue::Cast` with a reference as the operand * Correctly evaluate `mir::Rvalue::{Ref, AddressOf}` in constant propagation cc @Centril @RalfJung @oli-obk @eddyb cc #64490
2019-12-18Add Rvalue::AddressOf to MIRMatthew Jasper-21/+41
This operator creates a raw pointer to a Place directly, without first creating a reference. See RFC #2582 for motivation. The Rvalue is currently unused.
2019-12-15Remove now-redundant range check on u128 -> f32 castsRobin Kruppe-36/+7
This code was added to avoid UB in LLVM 6 and earlier, but we no longer support those LLVM versions. Since https://reviews.llvm.org/D47807 (released in LLVM 7), uitofp does exactly what we need. Closes #51872
2019-12-11Auto merge of #66650 - matthewjasper:nonuniform-array-move, r=pnkfelixbors-1/+2
Remove uniform array move MIR passes This PR fixes a number of bugs caused by limitations of this pass * Projections from constant indexes weren't being canonicalized * Constant indexes from the start weren't being canonicalized (they could have different min_lengths) * It didn't apply to non-moves This PR makes the following changes to support removing this pass: * ConstantIndex of arrays are now generated in a canonical form (from the start, min_length is the actual length). * Subslices are now split when generating move paths and when checking subslices have been moved. Additionally * The parent move path of a projection from an array element is now calculated correctly closes #66502

Update measureme crate to 0.5.0 This PR updates the `measureme` self-profiling crate to the latest release. Heads up, this version changes the trace file format, so the `summarize` tool on perf.rlo needs to be updated to 0.5 too. r? @Mark-Simulacrum cc @wesleywiser

Cleanup BodyCache After this PR: - `BodyCache` is renamed to `BodyAndCache` - `ReadOnlyBodyCache` is renamed to `ReadOnlyBodyAndCache` - `ReadOnlyBodyAndCache::body` fn is removed and all calls to it are replaced by a deref (possible due to fix of its `Deref` imp in #65947) cc @eddyb @oli-obk

Change unused_labels from allow to warn Fixes #66324, making the unused_labels lint warn instead of allow by default. I'm told @rust-lang/lang will need to review this, and perhaps will want to do a crater run.

2019-12-07Auto merge of #65881 - anp:implicit-caller-location, r=eddyb,oli-obkbors-12/+50
Implement #[track_caller] attribute. (RFC 2091 4/N) Implements the `#[track_caller]` attribute in both const and codegen contexts. The const implementation walks up the stack to find the nearest untracked callsite. The codegen implementation adds an implicit argument to tracked function calls, and populates it with either a call to the previously-landed intrinsic or if the caller has `#[track_caller]` with a copy of the location passed to the current function. Also includes a little cleanup and a few comments in the other caller location areas. [Depends on: 65664](https://github.com/rust-lang/rust/pull/65664) [RFC 2091 text](https://github.com/rust-lang/rfcs/blob/master/text/2091-inline-semantic.md) [Tracking issue](https://github.com/rust-lang/rust/issues/47809) [Tracking doc](https://paper.dropbox.com/doc/track_rfc_2091_impl-notes--Anf1NwnIb0xcRv31YLIadyj0Ag-rwCdRc2fi2yvRZ7syGZ9q#:uid=863513134494965680023183&h2=TODO-actually-pass-location-to)

rustc: split FnAbi's into definitions/direct calls ("of_instance") and indirect calls ("of_fn_ptr"). After this PR: * `InstanceDef::Virtual` is only used for "direct" virtual calls, and shims around those calls use `InstanceDef::ReifyShim` (i.e. for `<dyn Trait as Trait>::f as fn(_)`) * this could easily be done for intrinsics as well, to allow their reification, but I didn't do it * `FnAbi::of_instance` is **always** used for declaring/defining an `fn`, and for direct calls to an `fn` * this is great for e.g. https://github.com/rust-lang/rust/pull/65881 (`#[track_caller]`), which can introduce the "caller location" argument into "codegen signatures" by only changing `FnAbi::of_instance`, after this PR * `FnAbi::of_fn_ptr` is used primarily for indirect calls, i.e. to `fn` pointers * *not* virtual calls (which use `FnAbi::of_instance` with `InstanceDef::Virtual`) * there's also a couple uses where the `rustc_codegen_llvm` needs to declare (i.e. FFI-import) an LLVM function that has no Rust declaration available at all * at least one of them could probably be a "weak lang item" instead As there are many steps, this PR is best reviewed commit by commit - some of which arguably should be in their own PRs, I may have gotten carried away a bit. cc @nagisa @rkruppe @oli-obk @anp
