This fixes issues with RustAnalyzer not finding stable_mir crate.
It is also part of the long term architecture plan for these crates,
since we are moving towards having stable_mir depend on rustc_smir and
not the other way around.
I believe this is an utility function that will come handy eventually
for stable_mir users, but I'm keeping it as part of rustc_internal since
it initializes the StableMir context and requires `TyCtxt`.
Finally, I added the rustc_internal crate under a feature since the APIs
from this module shall not be stabilized.

Continuing the work from #137350.
Removes the unused methods: `expect_variant`, `expect_field`,
`expect_foreign_item`.
Every method gains a `hir_` prefix.
|
|
Continuing the work started in #136466.
Every method gains a `hir_` prefix, though for the ones that already
have a `par_` or `try_par_` prefix I added the `hir_` after that.
|
|
It's a trivial wrapper around the `hir_crate` query with a small number
of uses.
|
|
The end goal is to eliminate `Map` altogether.
I added a `hir_` prefix to all of them, that seemed simplest. The
exceptions are `module_items` which became `hir_module_free_items` because
there was already a `hir_module_items`, and `items` which became
`hir_free_items` for consistency with `hir_module_free_items`.

They were downgraded from queries in #123995 but they can just be
vanilla functions because they are not called in `rustc_middle`.
|
|
Instead use dcx.abort_if_error() or guar.raise_fatal() instead. These
guarantee that an error actually happened previously and thus we don't
silently abort.

`rustc_span::symbol` defines some things that are re-exported from
`rustc_span`, such as `Symbol` and `sym`. But it doesn't re-export some
closely related things such as `Ident` and `kw`. So you can do `use
rustc_span::{Symbol, sym}` but you have to do `use
rustc_span::symbol::{Ident, kw}`, which is inconsistent for no good
reason.
This commit re-exports `Ident`, `kw`, and `MacroRulesNormalizedIdent`,
and changes many `rustc_span::symbol::` qualifiers in `compiler/` to
`rustc_span::`. This is a 200+ net line of code reduction, mostly
because many files with two `use rustc_span` items can be reduced to
one.

It was inconsistently done (sometimes even within a single function) and
most of the rest of the compiler uses fatal errors instead, which need
to be caught using catch_with_exit_code anyway. Using fatal errors
instead of ErrorGuaranteed everywhere in the driver simplifies things a
bit.

The previous commit updated `rustfmt.toml` appropriately. This commit is
the outcome of running `x fmt --all` with the new formatting options.

`TyCtxt` impls `PpAnn` in `compiler/rustc_middle/src/hir/map/mod.rs`. We
can call that impl, which then calls the one on `intravisit::Map`,
instead of calling the one on `intravisit::Map` directly, avoiding a
cast and extra references.
|
|
Almost all callers want this anyway, and now we can use it to also return fed bodies

Remove `feed_local_def_id`

Basically I returned `TyCtxtFeed` from `create_def` and then preserved that in the local caches

Existing names for values of this type are `sess`, `parse_sess`,
`parse_session`, and `ps`. `sess` is particularly annoying because
that's also used for `Session` values, which are often co-located, and
it can be difficult to know which type a value named `sess` refers to.
(That annoyance is the main motivation for this change.) `psess` is nice
and short, which is good for a name used this much.
The commit also renames some `parse_sess_created` values as
`psess_created`.
|
|
It's clumsy and doesn't improve readability.

This is the only place aside from the global_ctxt query where it is
stolen.

`NoAnn` and `IdentifiedAnnotation` impl both `pprust_ast::PpAnn` and
`pprust_hir::PpAnn`, which is a bit confusing, because the optional
`tcx` is only needed for the HIR cases. (Currently the `tcx` is
unnecessarily provided in the `expanded` AST cases.)
This commit splits each one into `Ast` and `Hir` versions, which makes
things clear about where the `tcx` is needed. The commit also renames
all the traits so they consistently end with `Ann`.
|
|
This avoids the need for a bespoke `tcx.analysis()` call.
|
|
Because they all end up within a `TyCtxt`.
|
|
`call_with_pp_support_ast` and `call_with_pp_support_hir` how each have
a single call site. This commit inlines and removes them, which also
removes the need for all the supporting traits: `Sess`,
`AstPrinterSupport`, and `HirPrinterSupport`. The `sess` member is also
removed from several structs.
|
|
The handling of the `PpMode` variants is currently spread across three
functions: `print_after_parsing`, `print_after_hir_lowering`, and
`print_with_analysis`. Each one handles some of the variants. This split
is primarily because `print_after_parsing` has slightly different
arguments to the other two.
This commit changes the structure. It merges the three functions into a
single `print` function, and encapsulates the different arguments in a
new enum `PrintExtra`.
Benefits:
- The code is a little shorter.
- All the `PpMode` variants are handled in a single `match`, with no
need for `unreachable!` arms.
- It enables the trait removal in the subsequent commit by reducing
the number of `call_with_pp_support_ast` call sites from two to one.
|
|
First, both `AstPrinterSupport` and `HirPrinterSupport` have a `sess`
method. This commit introduces a `Sess` trait and makes the support
traits be subtraits of `Sess`, to avoid some duplication.
Second, both support traits have a `pp_ann` method that isn't needed if
we enable `trait_upcasting`. This commit removes those methods.
(Both of these traits will be removed in a subsequent commit, as will
the `trait_upcasting` use.)
|
|
|
|
It's simpler to distinguish the two AST modes directly in `PpMode`.
|
|
`phase_3_run_analysis_passes` no longer exists, and AFAICT this code has
been refactored so much since this comment was written that it no longer
has any useful meaning.
|
|
The callback is trivial and no pp support is actually needed. This makes
the `HirTree` case more like the `AstTree` case above.
|
|
- Rename `pprust` as `pprust_ast`, to align with `pprust_hir`.
- Rename `PrinterSupport` as `AstPrinterSupport`, to align with
`HirPrinterSupport`.

If `-o -` or `--emit KIND=-` is provided, output will be written
to stdout instead. Binary output (`obj`, `llvm-bc`, `link` and
`metadata`) being written this way will result in an error unless
stdout is not a tty. Multiple output types going to stdout will
trigger an error too, as they will all be mixded together.
