2025-02-11gccrs: add discriminant value intrinsicPhilip Herron11-62/+235
This is pretty nasty piece of rust in my opinion the return type of this intrinsic results into a lang item associated type: <T as DiscriminantKind>::Discriminant This is a special case which needs to support mapping onto the repr type of the associated ADT that is passed in, but defaults to iszie otherwise. This patch assumes we only come accross this case in a HIR::CALL_EXPR, so and makes assumutions that its always of this function signiture. I will do some checking in libcore to verify that assumption. More work is needed to parse the repr type on enums but the code is there to support this when its in to change the types etc. Addresses Rust-GCC#3348 gcc/rust/ChangeLog: * backend/rust-compile-intrinsic.cc (discriminant_value_handler): new handler * typecheck/rust-hir-trait-resolve.cc (TraitItemReference::resolve_item): track the defid * typecheck/rust-hir-type-check-base.cc (TypeCheckBase::parse_repr_options): default isize * typecheck/rust-hir-type-check-expr.cc (TypeCheckExpr::visit): special case CallExpr * typecheck/rust-hir-type-check-item.cc (TypeCheckItem::visit): parse repr options enum * typecheck/rust-hir-type-check-type.cc (TypeCheckType::visit): remove bad diagnostic * typecheck/rust-tyty.cc (PlaceholderType::PlaceholderType): track defid (PlaceholderType::clone): likewise (PlaceholderType::get_def_id): likeiwse * typecheck/rust-tyty.h: placeholder track defid * util/rust-lang-item.cc: add new lang items * util/rust-lang-item.h: likewise gcc/testsuite/ChangeLog: * rust/execute/torture/enum_intrinsics1.rs: New test.

This was a bad diagnostic added when I was working on slices and iterators also the name of the function is also bad. This is all about setting up associated types based on the current context of the bounds assocated with the associated trait bounds on this function.

2025-02-04gccrs: Fix compilation of trait-items which map to impl itemsPhilip Herron9-46/+129
When we have paths such as Try::from_error the Try references the Trait and then from_error references the from_error trait item. So this resolves directly to a trait implementation which has the type: fn <Self> (v: placeholder) -> Self Remember that a path such as: Try::from_error gets handled by doing a clever substitution: <T? as Try>::from_error The main piece here is that we resolve this function type and for monomoprhization we know this is a trait call but we know that all trait's have an implicit Self type param which in this case is Result<i32, i32> so when it comes to knowing which impl block this is we got rid of the old bad insert/lookup receiver hack and use the specified type to know which impl block we are talking about to generate the function. The hard part here is inside rust-compil-item.cc, where we have the 'concete' type which is the trait item fntype of: fn <Result<i32, i32>> (v : i32) -> Result<i32,i32> This does not really match the signiture of the impl item for Result which is: fn <T, E> (v: i32) -> Result<T, E> So what we need to do is actually infer this by inputing inference variables on the impl fntype then unify'ing the trait object to this to compute the types of this to monomorphize this.
