Proving `T::Assoc<_>: Sized` while a where-clause bound `T::Assoc<u8>: Sized` was in scope used to over-eagerly infer the unconstrained argument to `u8`, causing a spurious "mismatched types" error. It should compile; lock that in.
Add tests for generic function pointers Change FnPtr tests to use assert_eq!() rather than println!()
It had to be in rustc_resolve because there was no general attribute parsing infra back then, but now there is, so it should be there
LLVM 21 preserves the bounds assumption but does not eliminate the aggregate phi that LLVM 22 removes. Check each version's supported optimization and restore the shared postcondition so direct callers can eliminate bounds checks.
These extra layers of indirection are more confusing than helpful.
This has the pleasant side-effect of making `./x fix compiler` actually work, without breaking `./x clippy` (which relied on the hardcoded `Kind::Check`).
Also change the pkgsrc-wip link to indicate a more current rust version. To be re-visited again once 9.x reaches end of maintnance and EoL by the end of the current month.
…from` * Add support for wrapping of the return value of delegation * Cleanups * Review: use `make_lang_item_qpath`
…n-item statements
Fixes the builds of rustc and library/std for the L4Re target OS. A major change was done in linking binaries: The need for the L4Bender tool was removed and linking parameters are now fully configured in the rustc target config.
The field of `BodyOwnerKind` is computed via the exact same way as this check.
…r=petrochenkov delegation: fix determining wrong `FnKind` when delegation is inside const arg Fixes rust-lang#159127. Part of rust-lang#118212. r? @petrochenkov
derive(Diagnostic): link to proper docs I confirmed that this makes the doc comment show up in RA when hovering a `derive(Diagnostic)`. Also it's not correct that `note` etc can only be used on the struct, those attributes also work on (some) fields. So also fix the comment.
Clean up some manual debug impls
Some of these can just be derives. Others omitted fields, deliberately or not.
For example, the annotate emitter debug now looks like:

rustc_codegen_llvm: handle sm_101* features being an alias
LLVM 24 [moved sm_101{,a,f} features](llvm/llvm-project#214335) to just be an alias for the matching sm_110 feature. Since the sm_110 feature already exists, we can do the remapping unconditionally rather than gating it on LLVM 24.
