2024-08-31Rollup merge of #129725 - compiler-errors:predicates-of, r=fmeaseMatthias Krüger-0/+18
Stop using `ty::GenericPredicates` for non-predicates_of queries `GenericPredicates` is a struct of several parts: A list of of an item's own predicates, and a parent def id (and some effects related stuff, but ignore that since it's kinda irrelevant). When instantiating these generic predicates, it calls `predicates_of` on the parent and instantiates its predicates, and appends the item's own instantiated predicates too: https://github.com/rust-lang/rust/blob/acb4e8b6251f1d8da36f08e7a70fa23fc581839e/compiler/rustc_middle/src/ty/generics.rs#L407-L413 Notice how this should result in a recursive set of calls to `predicates_of`... However, `GenericPredicates` is *also* misused by a bunch of *other* queries as a convenient way of passing around a list of predicates. For these queries, we don't ever set the parent def id of the `GenericPredicates`, but if we did, then this would be very easy to mistakenly call `predicates_of` instead of some other intended parent query. Given that footgun, and the fact that we don't ever even *use* the parent def id in the `GenericPredicates` returned from queries like `explicit_super_predicates_of`, It really has no benefit over just returning `&'tcx [(Clause<'tcx>, Span)]`. This PR additionally opts to wrap the results of `EarlyBinder`, as we've tended to use that in the return type of these kinds of queries to properly convey that the user has params to deal with, and it also gives a convenient way of iterating over a slice of things after instantiating.

2024-03-22Always encode implied_predicates query for traitsMichael Goulet-12/+1
With associated type bounds enabled, the implied_predicates and super_predicates queries may differ for traits, since associated type bounds are also implied but are not counted as super predicates.

2024-02-16Auto merge of #120500 - oli-obk:intrinsics2.0, r=WaffleLapkinbors-1/+1
Implement intrinsics with fallback bodies fixes #93145 (though we can port many more intrinsics) cc #63585 The way this works is that the backend logic for generating custom code for intrinsics has been made fallible. The only failure path is "this intrinsic is unknown". The `Instance` (that was `InstanceDef::Intrinsic`) then gets converted to `InstanceDef::Item`, which represents the fallback body. A regular function call to that body is then codegenned. This is currently implemented for * codegen_ssa (so llvm and gcc) * codegen_cranelift other backends will need to adjust, but they can just keep doing what they were doing if they prefer (though adding new intrinsics to the compiler will then require them to implement them, instead of getting the fallback body). cc `@scottmcm` `@WaffleLapkin` ### todo * [ ] miri support * [x] default intrinsic name to name of function instead of requiring it to be specified in attribute * [x] make sure that the bodies are always available (must be collected for metadata)
