commit 4f772da8df444fbcb84821d4c4c60cf1cc2f5479 Author: Owen Avery <powerboat9.ga...@gmail.com> Date: Thu May 8 17:32:05 2025 -0400 Small improvements to DefaultASTVisitor and nr2.0 gcc/rust/ChangeLog: * ast/rust-ast-visitor.cc (DefaultASTVisitor::visit): Only visit the path of an instance of Visibility if the instance has a path. * ast/rust-ast.h (SimplePath::SimplePath): Make sure constructors are explicit. * resolve/rust-early-name-resolver-2.0.cc (Early::visit_attributes): Pass entire paths to NameResolutionContext::resolve_path. (Early::visit): Likewise and avoid copying a path. * resolve/rust-forever-stack.hxx (ForeverStack::resolve_path): Assert that at least one path segment has been passed in.
