2021-10-08Auto merge of #89619 - michaelwoerister:incr-vtables, r=nagisabors-1/+1
Turn vtable_allocation() into a query This PR removes the untracked vtable-const-allocation cache from the `tcx` and turns the `vtable_allocation()` method into a query. The change is pretty straightforward and should be backportable without too much effort. Fixes https://github.com/rust-lang/rust/issues/89598.

Introduce NullOp::AlignOf This PR introduces `Rvalue::NullaryOp(NullOp::AlignOf, ty)`, which will be lowered from `align_of`, similar to `size_of` lowering to `Rvalue::NullaryOp(NullOp::SizeOf, ty)`. The changes are originally part of #88700 but since it's not dependent on other changes and could have performance impact on its own, it's separated into its own PR.

2021-09-05Auto merge of #88499 - eddyb:layout-off, r=nagisabors-19/+17
Provide `layout_of` automatically (given tcx + param_env + error handling). After #88337, there's no longer any uses of `LayoutOf` within `rustc_target` itself, so I realized I could move the trait to `rustc_middle::ty::layout` and redesign it a bit. This is similar to #88338 (and supersedes it), but at no ergonomic loss, since there's no funky `C: LayoutOf<Ty = Ty>` -> `Ty: TyAbiInterface<C>` generic `impl` chain, and each `LayoutOf` still corresponds to one `impl` (of `LayoutOfHelpers`) for the specific context. After this PR, this is what's needed to get `trait LayoutOf` (with the `layout_of` method) implemented on some context type: * `TyCtxt`, via `HasTyCtxt` * `ParamEnv`, via `HasParamEnv` * a way to transform `LayoutError`s into the desired error type * an error type of `!` can be paired with having `cx.layout_of(...)` return `TyAndLayout` *without* `Result<...>` around it, such as used by codegen * this is done through a new `LayoutOfHelpers` trait (and so is specifying the type of `cx.layout_of(...)`) When going through this path (and not bypassing it with a manual `impl` of `LayoutOf`), the end result is that only the error case can be customized, the query itself and the success paths are guaranteed to be uniform. (**EDIT**: just noticed that because of the supertrait relationship, you cannot actually implement `LayoutOf` yourself, the blanket `impl` fully covers all possible context types that could ever implement it) Part of the motivation for this shape of API is that I've been working on querifying `FnAbi::of_*`, and what I want/need to introduce for that looks a lot like the setup in this PR - in particular, it's harder to express the `FnAbi` methods in `rustc_target`, since they're much more tied to `rustc` concepts. r? `@nagisa` cc `@oli-obk` `@bjorn3`

2021-09-03Auto merge of #88363 - michaelwoerister:remapped-diagnostics, r=estebankbors-2/+2
Path remapping: Make behavior of diagnostics output dependent on presence of --remap-path-prefix. This PR fixes a regression (#87745) with `--remap-path-prefix` where the flag stopped causing diagnostic messages to be remapped as well. The regression was introduced in https://github.com/rust-lang/rust/pull/83813 where we erroneously assumed that remapping of diagnostic messages was not desired anymore (because #70642 partially undid that functionality with nobody objecting). The issue is fixed by making `--remap-path-prefix` remap diagnostic messages again, including for paths that have been remapped in upstream crates (e.g. the standard library). This means that "sysroot-localization" (implemented in #70642) is also disabled if `rustc` is invoked with `--remap-path-prefix`. The assumption is that once someone starts explicitly remapping paths they also don't want paths to their local Rust installation in their build output. In the future we might want to give more fine-grained control over this behavior via compiler flags (see https://github.com/rust-lang/rfcs/pull/3127 for a related RFC). For now this PR is intended as a regression fix. This PR is an alternative to https://github.com/rust-lang/rust/pull/88191, which makes diagnostic messages be remapped unconditionally. That approach, however, would effectively revert #70642. Fixes https://github.com/rust-lang/rust/issues/87745. cc `@cbeuw` r? `@ghost`

The new implementation allows some `memcpy`s to be optimized away, so the uninit value in ui/sanitize/memory.rs is constructed directly onto the return place. Therefore the sanitizer now says that the value is allocated by `main` rather than `random`.
