The default install used to include rustc, rust-std, and rust-docs, but
the refactoring in commit 6b3413d825fa6 make rustc only default in
extended builds. This commit makes rustc installed by default again.
At the moment it is always missing for Cargo and RLS.
Their respective build systems need to be modified to include
`git-commit-hash` files in their "dist" tarballs.
Previously a `Symbol` was stored there, but this ended up causing hash
collisions in situations that otherwise shouldn't have a hash collision. Only
the symbol's string value was hashed, but it was possible for distinct symbols
to have the same string value, fooling various calcuations into thinking that
these paths *didn't* need disambiguating data when in fact they did!
By storing `InternedString` instead we're hopefully triggering all the exising
logic to disambiguate paths with same-name `Symbol` but actually distinct
locations.
This commit primarily removes the `stability` field from `TyCtxt` as well as its
internal mutable state, instead using a query to build the stability index as
well as primarily using queries for other related lookups.
Like previous commits the calculation of the stability index is wrapped in a
`with_ignore` node to avoid regressing the current tests, and otherwise this
commit also introduces #44232 but somewhat intentionally so.
Should hopefully more accurately reflect what's happening! This commit also
removes the cache in the cstore implementation as it's already cached through
the query infrastructure.
This commit makes the `maybe_unused_extern_crates` and
`maybe_unused_trait_imports` fields of `TyCtxt` private and ensures that they're
accessed with queries so the values and results can be tracked.
This removes a public mutable (but not actually used mutably) field from the
`TyCtxt`, moving it over to a query to ensure that it's tracked over time.
These are only called pre-TyCtxt (e.g. lowering/resolve), so make it explicit in
the name that they're untracked and therefore unsuitable to called elsewhere.
This commit moves the calculation of the `LanguageItems` structure into a
query rather than being calculated before the `TyCtxt` exists, with the eventual
end goal of removing some `CrateStore` methods.
The main use of `CrateStore` *before* the `TyCtxt` is created is during
resolution, but we want to be sure that any methods used before resolution are
not used after the `TyCtxt` is created. This commit starts moving the methods
used by resolve to all be named `{name}_untracked` where the rest of the
compiler uses just `{name}` as a query.
During this transition a number of new queries were added to account for
post-resolve usage of these methods.
This commit makes the `named_region_map` field of `GlobalCtxt` private by
encapsulating the fields behind new queries, and the new queries are also
targeted at particular `HirId` nodes instead of accessing the entire map.
This commit started by moving methods from `CrateStore` to queries, but it ended
up necessitating some deeper refactorings to move more items in general to
queries.
Before this commit the *resolver* would walk over the AST and process foreign
modules (`extern { .. }` blocks) and collect `#[link]` annotations. It would
then also process the command line `-l` directives and such. This information
was then stored as precalculated lists in the `CrateStore` object for iterating
over later.
After this, commit, however, this pass no longer happens during resolution but
now instead happens through queries. A query for the linked libraries of a crate
will crawl the crate for `extern` blocks and then process the linkage
annotations at that time.
This comit applies the following changes:
* Deletes the `is_allocator` query as it's no longer used
* Moves the `is_sanitizer_runtime` method to a query
* Moves the `is_profiler_runtime` method to a query
* Moves the `panic_strategy` method to a query
* Moves the `is_no_builtins` method to a query
* Deletes the cstore method of `is_compiler_builtins`. The query was added in
#42588 but the `CrateStore` method was not deleted
A good bit of these methods were used late in linking during trans so a new
dedicated structure was created to ship a calculated form of this information
over to the linker rather than having to ship the whole of `TyCtxt` over to
linking.
