* gccrs: Improve operator overload check for recursive overloadPhilip Herron2023-04-281-31/+59
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a case in #2019 where you have the default Add impl for i32 for example which has: impl Add for i32 { fn add(self, other:i32) { self + other } } This function will do a check for operator overload which then is able to find multiple candidates such as: impl<'a> Add<i32> for &'a i32 { type Output = <i32 as Add<i32>>::Output; fn add(self, other: i32) -> <i32 as Add<i32>>::Output { Add::add(*self, other) } } This initial operator overload will resolve to this as it looks like a valid candidate. This patch adds another level of checks to ensure the candidate does not equal the current context DefId.

* gccrs: qualified path syntax is used to disambiguate predicatesPhilip Herron2023-04-282-35/+66
| | | | | | | | | | | | | | | | | | | | | When resolving a qualified path we need to use the predicate to lookup the relevant assoicated impl block where possible. The issue here is that it might not have one due to a valid error in the impl block or it might be used within a trait this is a valid case. Generally we will be able to resolve to an impl block then it can grab that type and move on. Fixes #2135 gcc/rust/ChangeLog: * typecheck/rust-hir-type-check-path.cc (TypeCheckExpr::visit): use the predicate (TypeCheckExpr::resolve_segments): cleanup gcc/testsuite/ChangeLog: * rust/compile/issue-2135.rs: New test.

* gccrs: Add mechanism use pattern information to improve type infoPhilip Herron2023-04-265-13/+159
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When we have an untyped closure we assumed all parameters were inference variables but we can use the pattern type to try and improve the type info so if we have a reference pattern it must be a reference to an inference variables '&_'. This patch adds a new visitor to figure this out for untyped closure parameters. Note this test case does fully type resolve into the gimple: bool test::main::{{closure}} (struct test::main::{{closure}} $closure, struct (& u8) args) { ... } Though the Rustc version does fail type-resolution but we make some assumptions during comparison expressions here that they resolve to a bool this will change when we implement the comparison lang items.

* gccrs: Track Self properly with TypePredicateBoundsPhilip Herron2023-04-2612-49/+148
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When we handle generic trait bounds we never tracked its associated Self type. Its important to remember a Trait Predicate is associated with a type this means we end up missing a lot of helpful type information down the line relating to higher ranked trait bounds and associated types compuations. Remember traits have an implict Generic Type Parameter of Self we use this in computing trait defintions so in that case no associated type is specified which is to be expected but in all other cases we do even if it is generic its still useful type information to keep track of. There is one regression here with compile/issue-1893.rs this testcase mostly worked out as a fluke rather than a proper fix so its no suprise here it has regressed the other two test cases one where the number generic arguments has changed, Rustc gets around this and has a seperate error message for this case.
