2020-06-01Use the virtual name for libstd files in StableSourceFileId and also in theFelix S. Klock II-1/+1
encoded build artifacts. Fix #70924.
2020-06-01Split payload of FileName::Real to track both real and virutalized paths.Felix S. Klock II-9/+17
Such splits arise from metadata refs into libstd. This way, we can (in a follow on commit) continue to emit the virtual name into things like the like the StableSourceFileId that ends up in incremetnal build artifacts, while still using the devirtualized file path when we want to access the file. Note that this commit is intended to be a refactoring; the actual fix to the bug in question is in a follow-on commit.

2020-04-03Auto merge of #70642 - eddyb:remap-sysroot-src, r=Mark-Simulacrumbors-9/+53
Translate the virtual `/rustc/$hash` prefix back to a real directory. Closes #53486 and fixes #53081, by undoing the remapping to `/rustc/$hash` on the fly, when appropriate (e.g. our testsuites, or user crates that depend on `libstd`), but not during the Rust build itself (as that could leak the absolute build directory into the artifacts, breaking deterministic builds). Tested locally by setting `remap-debuginfo = true` in `config.toml`, which without these changes, was causing 56 tests to fail (see https://github.com/rust-lang/rust/issues/53081#issuecomment-606703215 for more details). cc @Mark-Simulacrum @alexcrichton @ehuss

2020-03-27Rollup merge of #70344 - Centril:hir-pretty, r=eddybDylan DPC-4/+10
Decouple `rustc_hir::print` into `rustc_hir_pretty` High level summary: - The HIR pretty printer, `rustc_hir::print` is moved into a new crate `rustc_hir_pretty`. - `rustc_ast_pretty` and `rustc_errors` are dropped as `rustc_hir` dependencies. - The dependence on HIR pretty is generally reduced, leaving `rustc_save_analysis`, `rustdoc`, `rustc_metadata`, and `rustc_driver` as the remaining clients. The main goal here is to reduce `rustc_hir`'s dependencies and its size such that it can start and finish earlier, thereby working towards https://github.com/rust-lang/rust/issues/65031. r? @Zoxc

Store idents for `DefPathData` into crate metadata Previously, we threw away the `Span` associated with a definition's identifier when we encoded crate metadata, causing us to lose location and hygiene information. We now store the identifier's `Span` in a side table, which gets encoded into the crate metadata. When we decode items from the metadata, we combine the name and span back into an `Ident`. This improves the output of several tests, which previously had messages suppressed due to dummy spans. This is a prerequisite for #68686, since throwing away a `Span` means that we lose hygiene information.

2020-03-23Rollup merge of #69968 - eddyb:tupled-closure-captures, r=nikomatsakisMazdak Farrokhzad-1/+1
rustc: keep upvars tupled in {Closure,Generator}Substs. Previously, each closure/generator capture's (aka "upvar") type was tracked as one "synthetic" type parameter in the closure/generator substs, and figuring out where the parent `fn`'s generics end and the synthetics start involved slicing at `tcx.generics_of(def_id).parent_count`. Needing to query `generics_of` limited @davidtwco (who wants to compute some `TypeFlags` differently for parent generics vs upvars, and `TyCtxt` is not available there), which is how I got started on this, but it's also possible that the `generics_of` queries are slowing down `{Closure,Generator}Substs` methods. To give an example, for a `foo::<T, U>::{closure#0}` with captures `x: X` and `y: Y`, substs are: * before this PR: `[T, U, /*kind*/, /*signature*/, X, Y]` * after this PR: `[T, U, /*kind*/, /*signature*/, (X, Y)]` You can see that, with this PR, no matter how many captures, the last 3 entries in the substs (or 5 for a generator) are always the "synthetic" ones, with the last one being the tuple of capture types. r? @nikomatsakis cc @Zoxc

2020-03-23Auto merge of #70204 - Centril:unshackled-lowering, r=Zoxcbors-5/+5
Liberate `rustc_ast_lowering` from `rustc` The whole point of this PR is the very last commit, in which we remove `rustc` as one of `rustc_ast_lowering`'s dependencies, thereby improving `./x.py` parallelism and working towards https://github.com/rust-lang/rust/issues/65031. Noteworthy: - From `rustc::arena` we move logic into `arena`, in particular `declare_arena!`. This is then used in `rustc_ast_lowering` so that lowering has its own separate arena. - Some linting code is unfortunately moved to `rustc_session::lint` cause its used both in `rustc_lint` and `rustc_ast_lowering`, and this is their common dependency. - `rustc_session::CrateDisambiguator` is moved into `rustc_ast` so that `rustc::hir::map::definitions` can be moved into `rustc_hir`, so that `rustc_ast_lowering` can stop referring to `rustc::hir`. r? @Zoxc

hir: replace "items" terminology with "nodes" where appropriate. The newly added `HirOwnerItems` confused me before I realized that "items" there actually referred to HIR nodes, not `hir:Item` or "item-like" (which we should IMO replace with "owner"). I suspect the naming had something to do with `ItemLocalId`'s use of "item". That is, `ItemLocalId` could be interpreted to mean one of two things: * `IntraItemNodeId` i.e. `IntraOwnerNodeId` * this is IMO correct, and I'd even like to rename it, but I didn't want to throw that into this PR * `IntraOwnerItemId` * this is what `HirOwnerItems` would seem to imply r? @Zoxc cc @michaelwoerister @nikomatsakis

Refactorings to get rid of rustc_codegen_utils r? @eddyb cc #45276 After this, the only modules left in `rustc_codegen_utils` are - `link`: a bunch of linking-related functions (many dealing with file names). These are mostly consumed by save analysis, rustc_driver, rustc_interface, and of course codegen. I assume they live here because we don't want a dependency of save analysis on codegen... Perhaps they can be moved to librustc? - ~`symbol_names` and `symbol_names_test`: honestly it seems odd that `symbol_names_test` is not a submodule of `symbol_names`. It seems like these could honestly live in their own crate or move to librustc. Already name mangling is exported as the `symbol_name` query.~ (move it to its own crate) I don't mind doing either of the above as part of this PR or a followup if you want.
