new trait solver: rebase impl substs for gats correctly
you might've caught this while working on projection code, if so then you can close this pr
r? `@lcnr`
Update instrument-coverage.md
explicitly set environment variable LLVM_PROFILE_FILE="default_%m.profraw" when starting cargo test, otherwise, only one `default.profraw ` is generated and will be overwritten if run unnittests and integration tests at the same time.
Heuristically undo path prefix mappings.
Because the compiler produces better diagnostics if it can find the source of (potentially remapped) dependencies.
The new test fails without the other changes in this PR. Let me know if you have better suggestions for the test directory. I moved the existing remapping test to be in the same location as the new one.
Some more context: I'm exploring running UI tests with remapped paths by default in https://github.com/rust-lang/rust/pull/105924 and this was one of the issues discovered.
This may also be useful in the context of https://github.com/rust-lang/rfcs/pull/3127 ("New rustc and Cargo options to allow path sanitisation by default").
Emit only one nbsp error per file
Fixes#106101.
See https://github.com/rust-lang/rust/issues/106098 for an explanation of how someone would end up with a large number of these nbsp characters in their source code, which is why I think rustc needs to handle this specific case in a friendlier way.
Rework some `predicates_of`/`{Generic,Instantiated}Predicates` code
1. Make `instantiate_own` return an iterator, since it's a bit more efficient and easier to work with
2. Remove `bound_{explicit,}_predicates_of` -- these `bound_` methods in particular were a bit awkward to work with since `ty::GenericPredicates` *already* acts kinda like an `EarlyBinder` with its own `instantiate_*` methods, and had only a few call sites anyways.
3. Implement `IntoIterator` for `InstantiatedPredicates`, since it's *very* commonly being `zip`'d together.
