rustc_middle: Remove trait `DefIdTree` This trait was a way to generalize over both `TyCtxt` and `Resolver`, but now `Resolver` has access to `TyCtxt`, so this trait is no longer necessary.

Remove legacy PM leftovers This drops two leftovers of legacy PM usage: * We don't need to initialize passes anymore. * The pass listing was still using legacy PM passes. Replace it with the corresponding new PM listing.

Name LLVM anonymous constants by a hash of their contents This makes the names stable between different versions of a crate unlike the `AllocId` naming, making LLVM IR comparisons with `llvm-diff` more practical.

2023-02-24Rename many interner functions.Nicholas Nethercote-8/+3
(This is a large commit. The changes to `compiler/rustc_middle/src/ty/context.rs` are the most important ones.) The current naming scheme is a mess, with a mix of `_intern_`, `intern_` and `mk_` prefixes, with little consistency. In particular, in many cases it's easy to use an iterator interner when a (preferable) slice interner is available. The guiding principles of the new naming system: - No `_intern_` prefixes. - The `intern_` prefix is for internal operations. - The `mk_` prefix is for external operations. - For cases where there is a slice interner and an iterator interner, the former is `mk_foo` and the latter is `mk_foo_from_iter`. Also, `slice_interners!` and `direct_interners!` can now be `pub` or non-`pub`, which helps enforce the internal/external operations division. It's not perfect, but I think it's a clear improvement. The following lists show everything that was renamed. slice_interners - const_list - mk_const_list -> mk_const_list_from_iter - intern_const_list -> mk_const_list - substs - mk_substs -> mk_substs_from_iter - intern_substs -> mk_substs - check_substs -> check_and_mk_substs (this is a weird one) - canonical_var_infos - intern_canonical_var_infos -> mk_canonical_var_infos - poly_existential_predicates - mk_poly_existential_predicates -> mk_poly_existential_predicates_from_iter - intern_poly_existential_predicates -> mk_poly_existential_predicates - _intern_poly_existential_predicates -> intern_poly_existential_predicates - predicates - mk_predicates -> mk_predicates_from_iter - intern_predicates -> mk_predicates - _intern_predicates -> intern_predicates - projs - intern_projs -> mk_projs - place_elems - mk_place_elems -> mk_place_elems_from_iter - intern_place_elems -> mk_place_elems - bound_variable_kinds - mk_bound_variable_kinds -> mk_bound_variable_kinds_from_iter - intern_bound_variable_kinds -> mk_bound_variable_kinds direct_interners - region - intern_region (unchanged) - const - mk_const_internal -> intern_const - const_allocation - intern_const_alloc -> mk_const_alloc - layout - intern_layout -> mk_layout - adt_def - intern_adt_def -> mk_adt_def_from_data (unusual case, hard to avoid) - alloc_adt_def(!) -> mk_adt_def - external_constraints - intern_external_constraints -> mk_external_constraints Other - type_list - mk_type_list -> mk_type_list_from_iter - intern_type_list -> mk_type_list - tup - mk_tup -> mk_tup_from_iter - intern_tup -> mk_tup
2023-02-22Auto merge of #108340 - eggyal:remove_traversal_trait_aliases, r=oli-obkbors-4/+4
Remove type-traversal trait aliases #107924 moved the type traversal (folding and visiting) traits into the type library, but created trait aliases in `rustc_middle` to minimise both the API churn for trait consumers and the arising boilerplate. As mentioned in that PR, an alternative approach of defining subtraits with blanket implementations of the respective supertraits was also considered at that time but was ruled out as not adding much value. Unfortunately, it has since emerged that rust-analyzer has difficulty with these trait aliases at present, resulting in a degraded contributor experience (see the recent [r-a has become useless](https://rust-lang.zulipchat.com/#narrow/stream/182449-t-compiler.2Fhelp/topic/r-a.20has.20become.20useless) topic on the #t-compiler/help Zulip stream). This PR removes the trait aliases, and accordingly the underlying type library traits are now used directly; they are parameterised by `TyCtxt<'tcx>` rather than just the `'tcx` lifetime, and imports have been updated to reflect the fact that the trait aliases' explicitly named traits are no longer automatically brought into scope. These changes also roll-back the (no-longer required) workarounds to #107747 that were made in b409329c624b9e3bbd7d8e07697e2e9f861a45b6. Since this PR is just a find+replace together with the changes necessary for compilation & tidy to pass, it's currently just one mega-commit. Let me know if you'd like it broken up. r? `@oli-obk`

Add `kernel-address` sanitizer support for freestanding targets This PR adds support for KASan (kernel address sanitizer) instrumentation in freestanding targets. I included the minimal set of `x86_64-unknown-none`, `riscv64{imac, gc}-unknown-none-elf`, and `aarch64-unknown-none` but there's likely other targets it can be added to. (`linux_kernel_base.rs`?) KASan uses the address sanitizer attributes but has the `CompileKernel` parameter set to `true` in the pass creation.

michaelwoerister:dont-merge-vtables-when-debuginfo, r=WaffleLapkin Don't merge vtables when full debuginfo is enabled. This PR makes the compiler not emit the `unnamed_addr` attribute for vtables when full debuginfo is enabled, so that they don't get merged even if they have the same contents. This allows debuggers to more reliably map from a dyn pointer to the self-type of a trait object by looking at the vtable's debuginfo. The PR only changes the behavior of the LLVM backend as other backends don't emit vtable debuginfo (as far as I can tell). The performance impact of this change should be small as [measured](https://github.com/rust-lang/rust/pull/103514#issuecomment-1290833854) in a previous PR.
