2024-10-02gccrs: Fix ICE when typechecking non-trait item when we expect onePhilip Herron5-17/+46
We just had an assertion here for this case where we expect a trait. This changes the assertion into error handling producing the correct error code with fixit suggestion like rustc. Fixes #2499 gcc/rust/ChangeLog: * typecheck/rust-hir-trait-resolve.cc (TraitResolver::resolve_path_to_trait): use error handling instead of assertion * typecheck/rust-hir-type-check-item.cc (TypeCheckItem::visit): reuse trait reference * typecheck/rust-hir-type-check-item.h: update prototype gcc/testsuite/ChangeLog: * rust/compile/nr2/exclude: nr2 cant handle this * rust/compile/issue-2499.rs: New test.

2024-09-27rust: Add support for Clone and Copy derive on generic typesPhilip Herron16-22/+783
When we generate derivations for Copy and Clone we need to make sure the associated impl block sets up the generic parameters and arguments correctly. This patch introduces the framework to copy chunks of the AST because we need to make sure these new AST nodes have their own associated id, calling clone on the nodes will just confuse name-resolution and subsequent mappings.
