Not thrilled with some of this boilerplate, but it does seem like an improvement. gcc/rust/ChangeLog: * ast/rust-expr.h (InlineAsmOperand): Replace multiple mutually-exclusive tl::optional fields with a std::unique_ptr and modify nested classes to allow this. Also, make getters return references where possible. * expand/rust-macro-builtins-asm.cc (parse_reg_operand_out): Pass location when constructing InlineAsmOperand.

2025-03-19rust: Add support for Clone and Copy derive on generic typesPhilip Herron4-16/+168
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. Fixes #3139 gcc/rust/ChangeLog: * Make-lang.in: new objects * ast/rust-ast-builder.cc (Builder::generic_type_path_segment): new helper (Builder::single_generic_type_path): likewise (Builder::new_type): likewise (Builder::new_lifetime_param): likewise (Builder::new_type_param): likewise (Builder::new_lifetime): likewise (Builder::new_generic_args): likewise * ast/rust-ast-builder.h: new helper decls * ast/rust-ast.h: new const getters * ast/rust-path.h: likewise * ast/rust-type.h: likewise * expand/rust-derive-clone.cc (DeriveClone::clone_impl): take the types generics (DeriveClone::visit_tuple): likewise (DeriveClone::visit_struct): likewise (DeriveClone::visit_union): likewise * expand/rust-derive-clone.h: update header * expand/rust-derive-copy.cc (DeriveCopy::copy_impl): similarly take type generics (DeriveCopy::visit_struct): likewise (DeriveCopy::visit_tuple): likewise (DeriveCopy::visit_enum): likewise (DeriveCopy::visit_union): likewise * expand/rust-derive-copy.h: likewse * ast/rust-ast-builder-type.cc: New file. * ast/rust-ast-builder-type.h: New file. gcc/testsuite/ChangeLog: * rust/compile/issue-3139-1.rs: New test. * rust/compile/issue-3139-2.rs: New test. * rust/compile/issue-3139-3.rs: New test. * rust/compile/nr2/exclude: these all break nr2
