2025-08-05gccrs: Add rest pattern support for AST::SlicePatternYap Zhi Heng1-11/+61
The main change can be found in ast/rust-pattern.h, which introduces 2 item types for AST::SlicePattern - one without rest pattern (SlicePatternItemsNoRest) & the other with it (SlicePatternItemsHasRest). This led to a number of cascading changes as seen in the changelog. gcc/rust/ChangeLog: * ast/rust-ast-collector.cc: Add support for the 2 new classes. * ast/rust-ast-collector.h: Header file update for above. * ast/rust-ast-full-decls.h: Add forward decls for the 2 new classes. * ast/rust-ast-visitor.cc: Add visit support for the 2 new classes. * ast/rust-ast-visitor.h: Header file update for above. * ast/rust-pattern.cc: Implementation of certain methods for the 2 new classes. * ast/rust-pattern.h: Define the 2 new classes. Update SlicePattern to be able to hold 2 kinds of items - SlicePatternItemsNoRest or SlicePatternItemsRest. * expand/rust-cfg-strip.cc: Add support for the 2 new classes. * expand/rust-cfg-strip.h: Header file update for above. * expand/rust-derive.h: Add visits for the 2 new classes. * hir/rust-ast-lower-base.cc: Add visits for the 2 new classes. * hir/rust-ast-lower-base.h: Header file update for above. * hir/rust-ast-lower-pattern.cc: Update lowering of SlicePattern to support SlicePatternItemsNoRest. * parse/rust-parse-impl.h (parse_slice_pattern()): Add support for parsing DOT_DOT into respective SlicePatternItems. * resolve/rust-ast-resolve-base.cc: Add visits for the 2 new classes. * resolve/rust-ast-resolve-base.h: Header file update for above. * resolve/rust-ast-resolve-pattern.cc: Update SlicePattern resolution to support new classes.

2025-08-05gccrs: Parse try expressionsOwen Avery2-0/+34

2025-08-05gccrs: desugar APIT impl traitsPhilip Herron1-11/+2
Argument position impl traits are simply syntatic sugar for generics. This adds a new desugar pass to do this. So for example: fn foo(a: impl Value, b: impl Value) -> i32 Is desugared into: fn foo<T: Value, U: Value> (a: T, b: U) -> i32 So it just works like any normal generic function. There are more complex cases such as: fn foo(_value: impl Bar<Baz = impl Foo>) -> i32 Which has a generic argument binding which needs to be turned into a where constraint: fn foo<T, U>(_value: T) -> i32 where T: Bar<Baz = U>, U: Foo, Fixes Rust-GCC#2015 Fixes Rust-GCC#1487 Fixes Rust-GCC#3454 Fixes Rust-GCC#1482 gcc/rust/ChangeLog: * Make-lang.in: new desugar file * ast/rust-ast.cc (ImplTraitTypeOneBound::as_string): its a unique_ptr now (FormatArgs::set_outer_attrs): reformat * ast/rust-path.h: remove has_generic_args assertion (can be empty because of desugar) * ast/rust-type.h (class ImplTraitTypeOneBound): add copy ctor and use unique_ptr * hir/rust-ast-lower-type.cc (ASTLoweringType::visit): update to use unique_ptr * parse/rust-parse-impl.h (Parser::parse_type): reuse the existing unique_ptr instead (Parser::parse_type_no_bounds): likewise (Parser::parse_pattern): likewise * resolve/rust-ast-resolve-type.cc (ResolveType::visit): its a unique_ptr now * rust-session-manager.cc (Session::compile_crate): call desugar * ast/rust-desugar-apit.cc: New file. * ast/rust-desugar-apit.h: New file. gcc/testsuite/ChangeLog: * rust/compile/issue-2015.rs: fully supported now * rust/compile/nr2/exclude: nr2 cant handle some of these * rust/compile/issue-1487.rs: New test. * rust/compile/issue-3454.rs: New test. * rust/execute/torture/impl_desugar-2.rs: New test. * rust/execute/torture/impl_desugar.rs: New test. * rust/execute/torture/impl_trait1.rs: New test. * rust/execute/torture/impl_trait2.rs: New test. * rust/execute/torture/impl_trait3.rs: New test. * rust/execute/torture/impl_trait4.rs: New test. * rust/execute/torture/issue-1482.rs: New test.
