compiler/rustc_middle/src/hir/map/mod.rs

What about this?

Suggested change

if self.tcx.hir().is_body_owner(item.def_id) {

if associated_body(Node::Item(item)).is_some() {

cjgillot · 2022-06-18T08:23:31Z

compiler/rustc_middle/src/hir/map/mod.rs

We want to record the LocalDefId of the closure. hir_id.owner is the one of the closure's surrounding item-like (that we have already recorded in visit_*item).

Suggested change

self.body_owners.push(ex.hir_id.owner);

self.body_owners.push(self.tcx.hir().local_def_id(ex.hir_id));

Likewise for anon consts.

cjgillot · 2022-06-18T08:24:11Z

compiler/rustc_middle/src/hir/map/mod.rs

This probably pushes the same LocalDefId twice.

Thanks, that was the problem.

cjgillot

Sorry for the delay @kckeiks, I had not realized you were waiting for me.

cjgillot · 2022-07-05T15:46:50Z

compiler/rustc_middle/src/hir/map/mod.rs

This is always true.

cjgillot · 2022-07-05T15:46:57Z

compiler/rustc_middle/src/hir/map/mod.rs

associated_body(...).is_some() is always true on closures.

cjgillot · 2022-07-05T15:47:39Z

compiler/rustc_middle/src/hir/map/mod.rs

This is always false.

Could you inline the definition of associated_body here?

cjgillot · 2022-07-05T15:48:46Z

compiler/rustc_middle/src/hir/map/mod.rs

I wonder if we can merge this visitor and the one for hir_module_items using some flag to switch behaviour.

cjgillot · 2022-07-05T15:50:28Z

compiler/rustc_middle/src/hir/map/mod.rs

Is this used anywhere?

Sorry, I forgot to remove this.

cjgillot · 2022-07-05T15:50:42Z

compiler/rustc_middle/src/hir/map/mod.rs

This case is possibly wrong.

cjgillot · 2022-07-05T15:50:50Z

compiler/rustc_middle/src/hir/map/mod.rs

This one too.

par_iter(self.tcx.hir_crate_items(()).body_owners.to_vec()).for_each(|def_id| f(def_id));

par_iter(&self.tcx.hir_crate_items(()).body_owners[..]).for_each(|&def_id| f(def_id));

?

cjgillot · 2022-07-13T15:36:08Z

compiler/rustc_middle/src/hir/map/mod.rs

This will insert a module as its own submodule. We should probably handle all ItemKind::Mod in visit_item.

I think the if-else in visit_item would prevent that from happening? visit_mod gets called only by walk_item.

if !self.crate_collector && let ItemKind::Mod(..) = item.kind { // If this declares another module, do not recurse inside it. self.submodules.push(item.def_id); } else { intravisit::walk_item(self, item) }

visit_mod is the entry point called by hir_module_items.
