2023-07-04Auto merge of #113303 - compiler-errors:yeet-chalk, r=lcnrbors-3864/+35
Remove chalk support from the compiler Removes chalk (`-Ztrait-solver=chalk`) from the compiler and prunes any dead code resulting from this, mainly: * Remove the chalk compatibility layer in `compiler/rustc_traits/src/chalk` * Remove the chalk flag `-Ztrait-solver=chalk` and its `TraitEngine` implementation * Remove `TypeWellFormedFromEnv` (and its many `bug!()` match arms) * Remove the chalk migration mode from compiletest * Remove the `chalkify` UI tests (do we want to keep any of these, but migrate them to `-Ztrait-solver=next`??) Fulfills rust-lang/types-team#93. r? `@jackh726`

davidtwco:issue-94223-external-abi-fn-ptr-in-internal-abi-fn, r=jackh726 lint/ctypes: ext. abi fn-ptr in internal abi fn Fixes #94223. - In the improper ctypes lint, instead of skipping functions with internal ABIs, check that the signature doesn't contain any fn-ptr types with external ABIs that aren't FFI-safe. - When computing the ABI for fn-ptr types, remove an `unwrap` that assumed FFI-safe types in foreign fn-ptr types. - I'm not certain that this is the correct approach.

2023-07-03Rollup merge of #112869 - compiler-errors:sketchy-new-select, r=lcnrGuillaume Gomez-77/+429
Implement selection via new trait solver Implements selection via the new solver by calling into `assemble_and_evaluate_candidates`, doing a very light-weight "winnow" to choose one candidate over the others, and then re-confirming that candidate outside of the `EvalCtxt` in order to compute the information necessary for the `ImplSource`. This selection routine is best effort -- if it receives an ambiguous response from the `EvalCtxt`, then it may return ambiguity if the work to re-confirm the goal is not "easy" -- right now, that means everything except for object and impl goals. Since we don't want to reimplement all of the work of the `compute_builtin_*` methods in the solver internals, we bail out if we encounter ambiguity more often than the old solver. This should only barely affect [method selection](https://github.com/rust-lang/rust/blob/f798ada7babac06d4611b0b3a6079d8399ab58ab/compiler/rustc_hir_typeck/src/method/probe.rs#L1447) and not codegen. It can be made more precise later if needed. r? `@lcnr`

2023-07-03Auto merge of #113288 - Nilstrieb:revert-dev, r=oli-obkbors-13/+4
Revert "Suggest `x build library` for a custom toolchain that fails to load `core`" This reverts commit b913f5593d2e2698d18034b56dd538ee745f1adc. CI builds with profile=nightly, causing different test output. Making the output depend on the release channel was not a great idea and we have to be more careful with this. I did not realize that the change could have such effects on test output but it's kinda obvious with hindsight >.<.

implement deep normalization via the new solver together with #112869 this should remove all uses of the old solver with `-Ztrait-solver=next`. see https://hackmd.io/V0qsUB_fTxexfQO_pcOcrg for a description of this PR.

2023-07-03Auto merge of #112882 - DrMeepster:new_un_derefer, r=oli-obkbors-136/+137
Rewrite `UnDerefer` Currently, `UnDerefer` is used by drop elaboration to undo the effects of the `Derefer` pass. However, it just recreates the original places with derefs in the middle of the projection. Because `ProjectionElem::Deref` is intended to be removed completely in the future, this will not work forever. This PR introduces a `deref_chain` method that returns the places behind `DerefTemp` locals in a place and rewrites the move path code to use this. In the process, `UnDerefer` was merged into `MovePathLookup`. Now that move paths use the same places as in the MIR, the other uses of `UnDerefer` no longer require it.
