2020-08-22Lazy decoding of DefPathTable from crate metadata (non-incremental case)Aaron Hill-3/+6
2020-08-18Auto merge of #75635 - Aaron1011:fix/incr-fn-param-names, r=eddybbors-4/+0
Don't use `dep_graph.with_ignore` when encoding fn param names The call to `with_ignore` was added years ago, and should no longer be necessary with the modern incremental query infrastructure. I also removed a related FIXME comment for issue #38501, which was closed months ago.

2020-08-08Eliminate the `SessionGlobals` from `librustc_ast`.Nicholas Nethercote-2/+1
By moving `{known,used}_attrs` from `SessionGlobals` to `Session`. This means they are accessed via the `Session`, rather than via TLS. A few `Attr` methods and `librustc_ast` functions are now methods of `Session`. All of this required passing a `Session` to lots of functions that didn't already have one. Some of these functions also had arguments removed, because those arguments could be accessed directly via the `Session` argument. `contains_feature_attr()` was dead, and is removed. Some functions were moved from `librustc_ast` elsewhere because they now need to access `Session`, which isn't available in that crate. - `entry_point_type()` --> `librustc_builtin_macros` - `global_allocator_spans()` --> `librustc_metadata` - `is_proc_macro_attr()` --> `Session`

2020-03-24Rollup merge of #70077 - Aaron1011:feature/new-def-path-ident, r=petrochenkovMazdak Farrokhzad-3/+3
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.

2020-03-21Rollup merge of #70092 - eddyb:hir-items-are-just-nodes, r=ZoxcMazdak Farrokhzad-1/+1
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

Use `ast::MacroDef` instead. Also remove `Session::imported_macro_spans`, external macros have spans now.
2020-03-10Auto merge of #66364 - Centril:cleanup-macro-def, r=petrochenkov,eddybbors-27/+14
Cleanup `rmeta::MacroDef` Avoid using rountrip parsing in the encoder and in `fn load_macro_untracked`. The main reason I was interested in this was to remove `rustc_parse` as a dependency of `rustc_metadata` but it seems like this had other benefits as well. Fixes #49511. r? @eddyb cc @matthewjasper @estebank @petrochenkov

rustc_metadata: Load metadata for indirect macro-only dependencies Imagine this dependency chain between crates ``` Executable crate -> Library crate -> Macro crate ``` where "Library crate" uses the macros from "Macro crate" for some code generation, but doesn't reexport them any further. Currently, when compiling "Executable crate" we don't even load metadata for it, because why would we want to load any metadata from "Macro crate" if it already did all its code generation job when compiling "Library crate". Right? Wrong! Hygiene data and spans (https://github.com/rust-lang/rust/issues/68686, https://github.com/rust-lang/rust/pull/68941) from "Macro crate" still may need to be decoded from "Executable crate". So we'll have to load them properly. Questions: - How this will affect compile times for larger crate trees in practice? How to measure it? Hygiene/span encoding/decoding will necessarily slow down compilation because right now we just don't do some work that we should do, but this introduces a whole new way to slow down things. E.g. loading metadata for `syn` (and its dependencies) when compiling your executable if one of its library dependencies uses it. - We are currently detecting whether a crate reexports macros from "Macro crate" or not, could we similarly detect whether a crate "reexports spans" and keep it unloaded if it doesn't? Or at least "reexports important spans" affecting hygiene, we can probably lose spans that only affect diagnostics.

build-std compatible sanitizer support ### Motivation When using `-Z sanitizer=*` feature it is essential that both user code and standard library is instrumented. Otherwise the utility of sanitizer will be limited, or its use will be impractical like in the case of memory sanitizer. The recently introduced cargo feature build-std makes it possible to rebuild standard library with arbitrary rustc flags. Unfortunately, those changes alone do not make it easy to rebuild standard library with sanitizers, since runtimes are dependencies of std that have to be build in specific environment, generally not available outside rustbuild process. Additionally rebuilding them requires presence of llvm-config and compiler-rt sources. The goal of changes proposed here is to make it possible to avoid rebuilding sanitizer runtimes when rebuilding the std, thus making it possible to instrument standard library for use with sanitizer with simple, although verbose command: ``` env CARGO_TARGET_X86_64_UNKNOWN_LINUX_GNU_RUSTFLAGS=-Zsanitizer=thread cargo test -Zbuild-std --target x86_64-unknown-linux-gnu ``` ### Implementation * Sanitizer runtimes are no long packed into crates. Instead, libraries build from compiler-rt are used as is, after renaming them into `librusc_rt.*`. * rustc obtains runtimes from target libdir for default sysroot, so that they are not required in custom build sysroots created with build-std. * The runtimes are only linked-in into executables to address issue #64629. (in previous design it was hard to avoid linking runtimes into static libraries produced by rustc as demonstrated by sanitizer-staticlib-link test, which still passes despite changes made in #64780). cc @kennytm, @japaric, @firstyear, @choller
