2025-08-05gccrs: Add initial support for const genericsPhilip Herron2-2/+6
In order to support const generics we map the declarations to a ConstType this means we reuse all our existing type coercion, unification code and generic substitutions code to support this with minimal impact. This patch adds support for: 1. Default const generics 2. Infer const generics 3. ADTType suport 4. unconstrained checks 5. ensure types of the const generic and default 6. validation if passing a const argument to a type argument Lots of test cases now work and new ones added.

2025-08-05gccrs: Add initial support for deffered operator overload resolutionPhilip Herron3-9/+45
In the test case: fn test (len: usize) -> u64 { let mut i = 0; let mut out = 0; if i + 3 < len { out = 123; } out } The issue is to determine the correct type of 'i', out is simple because it hits a coercion site in the resturn position for u64. But 'i + 3', 'i' is an integer infer variable and the same for the literal '3'. So when it comes to resolving the type for the Add expression we hit the resolve the operator overload code and because of this: macro_rules! add_impl { ($($t:ty)*) => ($( impl Add for $t { type Output = $t; #[inline] #[rustc_inherit_overflow_checks] fn add(self, other: $t) -> $t { self + other } } )*) } add_impl! { usize u8 u16 u32 u64 u128 isize i8 i16 i32 i64 i128 f32 f64 } This means the resolution for 'i + 3' is ambigious because it could be any of these Add implementations. But because we unify against the '< len' where len is defined as usize later in the resolution we determine 'i' is actually a usize. Which means if we defer the resolution of this operator overload in the ambigious case we can simply resolve it at the end.

2025-08-05gccrs: Adjust external crate lowering and type checkingOwen Avery2-0/+20
The 2.0 name resolver is provided through ImmutableNameResolutionContext after it is done being mutated. The typechecker attempts to use ImmutableNameResolutionContext, so it needs to be run after ImmutableNameResolutionContext has been initialized (after all name resolution has been completed). Additionally, although I haven't seen any issues with lowering AST to HIR before name resolution 2.0 is complete, it makes sense to perform all lowering in lockstep as well. gcc/rust/ChangeLog: * hir/rust-ast-lower-item.cc (ASTLoweringItem::visit): Add visitor for ExternCrate. * hir/rust-ast-lower-item.h (ASTLoweringItem::visit): Likewise. * rust-session-manager.cc (Session::load_extern_crate): Avoid lowering or type resolving external crates here. * typecheck/rust-hir-type-check-item.cc (TypeCheckItem::visit): Add visitor for ExternCrate. * typecheck/rust-hir-type-check-item.h (TypeCheckItem::visit): Replace empty definition with a declaration.

2025-08-05gccrs: Prevent passing generic arguments to impl traits in argument positionPhilip Herron3-14/+14
When using impl traits in argument position (APIT), they are desugared into generics, and supplying explicit generic arguments is not allowed. This commit adds the error diagnostic E0632 for attempting to pass generic arguments to impl traits, completing the implementation of the APIT feature. gcc/rust/ChangeLog: * ast/rust-desugar-apit.cc: track if this is a impl-trait generic * ast/rust-item.h (class TypeParam): add field to track if from impl trait * hir/rust-ast-lower-type.cc (ASTLowerGenericParam::visit): likewise * hir/tree/rust-hir-item.cc (TypeParam::TypeParam): upate hir as well (TypeParam::operator=): likewise * hir/tree/rust-hir-item.h (class TypeParam): likewise * typecheck/rust-tyty-subst.cc (SubstitutionParamMapping::get_generic_param): add error * typecheck/rust-tyty-subst.h: add const getter for the associated TypeParm gcc/testsuite/ChangeLog: * rust/compile/nr2/exclude: nr2 cant handle this * rust/compile/impl_trait_generic_arg.rs: New test.

2025-08-05gccrs: desugar APIT impl traitsPhilip Herron1-1/+1
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.
