debuginfo: Fix ICE when generating name for type that produces a layout error.

2022-03-16T14:57:33+00:00

Rollup merge of #94810 - michaelwoerister:fix-trait-pointer-debuginfo-names, r=wesleywiser

2022-03-15T16:15:52+00:00

debuginfo: Fix bug in type name generation for dyn types with associated types but no other generic arguments. For types like `&dyn Future` the compiler currently emits invalid types names in debuginfo. This PR fixes this. Before: ```txt // DWARF &dyn core::future::future::Future, Output=bool> // CodeView ref$ > > > ``` After: ```txt // DWARF &dyn core::future::future::Future // CodeView ref$ > > > ``` These syntactically incorrect type names can cause downstream tools (e.g. debugger extensions) crash when trying to parse them. r? `@wesleywiser`

debuginfo: Refactor debuginfo generation for types

2022-03-14T15:49:06+00:00

This commit - changes names to use di_node instead of metadata - uniformly names all functions that build new debuginfo nodes build_xyz_di_node - renames CrateDebugContext to CodegenUnitDebugContext (which is more accurate) - moves TypeMap and functions that work directly work with it to a new type_map module - moves and reimplements enum related builder functions to a new enums module - splits enum debuginfo building for the native and cpp-like cases, since they are mostly separate - uses SmallVec instead of Vec in many places - removes the old infrastructure for dealing with recursion cycles (create_and_register_recursive_type_forward_declaration(), RecursiveTypeDescription, set_members_of_composite_type(), MemberDescription, MemberDescriptionFactory, prepare_xyz_metadata(), etc) - adds type_map::build_type_with_children() as a replacement for dealing with recursion cycles - adds many (doc-)comments explaining what's going on - changes cpp-like naming for C-Style enums so they don't get a enum$<...> name (because the NatVis visualizer does not apply to them) - fixes detection of what is a C-style enum because some enums where classified as C-style even though they have fields - changes the position of discriminant debuginfo node so it is consistently nested inside the top-level union instead of, sometimes, next to it

Improve `AdtDef` interning.

2022-03-11T02:31:24+00:00

This commit makes `AdtDef` use `Interned`. Much the commit is tedious changes to introduce getter functions. The interesting changes are in `compiler/rustc_middle/src/ty/adt.rs`.
