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.

2020-01-23Add `-Z no-link` flagVictor Ding-2/+3
Adds a compiler option to allow rustc compile a crate without linking. With this flag, rustc serializes codegen_results into a .rlink file.

2019-11-11Move allocator_kind to CrateStoreMark Rousskov-0/+2
Similarly to the previous commit, there's no need for this to be in Session and have a Once around it.
2019-11-11Move injected_panic_runtime to CrateStoreMark Rousskov-0/+1
This was essentially a "query" previously (with no key, just always run once when resolving the crate dependencies), and remains so, just now in a way that isn't on Session. This removes the need for the `Once` as well.
2019-10-31Implement dual proc macro hashingmsizanoen-0/+1
This changes the mechanism of `-Z dual-proc-macro` to record the host proc macro hash in the transistive dependency information and use it during dependency resolution instead of resolving only by name.
2019-10-24rustc_metadata: Minimize use of `Lrc` in crate storeVadim Petrochenkov-3/+3
Crate metadatas are still stored as `Lrc<CrateMetadata>` in `CStore` because crate store has to be cloneable due to `Resolver::clone_outputs`.

2019-09-27getting more context for duplicate lang items (fixes #60561)Tomas Tauber-1/+8
Where possible, the error message includes the name of the crate that brought in the crate with duplicate lang items (which helps with debugging). This information is passed on from cstore using the `extern_crate` query.

2018-09-29don't elide lifetimes in paths in librustc/Zack M. Davis-1/+1
This seemed like a good way to kick the tires on the elided-lifetimes-in-paths lint (#52069)—seems to work! This was also pretty tedious—it sure would be nice if `cargo fix` worked on this codebase (#53896)!
