gcc/rust/ChangeLog: * resolve/rust-early-name-resolver-2.0.cc (Early::resolve_glob_import): Use NameResolutionContext::resolve_path instead of ForeverStack::resolve_path. (Early::visit): Likewise. (Early::visit_attributes): Likewise. * resolve/rust-early-name-resolver-2.0.h (Early::resolve_path_in_all_ns): Likewise. * resolve/rust-late-name-resolver-2.0.cc (Late::visit): Likewise and insert segment resolutions not handled by NameResolutionContext::resolve_path. * resolve/rust-name-resolution-context.h (NameResolutionContext::resolve_path): Add. * typecheck/rust-hir-type-check-path.cc (TypeCheckExpr::resolve_root_path): Use segment node ids instead of the path node id to look up segment resolutions when using the 2.0 resolver, as is done with the 1.0 resolver. * typecheck/rust-hir-type-check-type.cc (TypeCheckType::resolve_root_path): Likewise. * resolve/rust-forever-stack.h (ForeverStack::resolve_path): Add callback parameter for inserting segment resolutions. (ForeverStack::find_starting_point): Likewise. (ForeverStack::resolve_segments): Likewise. * resolve/rust-forever-stack.hxx (ForeverStack::find_starting_point): Likewise. (ForeverStack::resolve_segments): Likewise. (ForeverStack::resolve_path): Likewise. Signed-off-by: Owen Avery <powerboat9.gamer@gmail.com>

It looks like this might need something like #3220 to prevent test regressions |

When name resolution 2.0 is enabled these sections of the typechecker should be performing resolution lookups using segment node ids, rather than path node ids, as is done when name resolution 1.0 is enabled. Since name resolution 2.0 doesn't currently insert resolutions for individual segments, lookups based on path node id are left as a fallback.
