2022-02-15Overhaul `Const`.Nicholas Nethercote-1/+1
Specifically, rename the `Const` struct as `ConstS` and re-introduce `Const` as this: ``` pub struct Const<'tcx>(&'tcx Interned<ConstS>); ``` This now matches `Ty` and `Predicate` more closely, including using pointer-based `eq` and `hash`. Notable changes: - `mk_const` now takes a `ConstS`. - `Const` was copy, despite being 48 bytes. Now `ConstS` is not, so need a we need separate arena for it, because we can't use the `Dropless` one any more. - Many `&'tcx Const<'tcx>`/`&Const<'tcx>` to `Const<'tcx>` changes - Many `ct.ty` to `ct.ty()` and `ct.val` to `ct.val()` changes. - Lots of tedious sigil fiddling.
2022-02-15Overhaul `TyS` and `Ty`.Nicholas Nethercote-4/+4
Specifically, change `Ty` from this: ``` pub type Ty<'tcx> = &'tcx TyS<'tcx>; ``` to this ``` pub struct Ty<'tcx>(Interned<'tcx, TyS<'tcx>>); ``` There are two benefits to this. - It's now a first class type, so we can define methods on it. This means we can move a lot of methods away from `TyS`, leaving `TyS` as a barely-used type, which is appropriate given that it's not meant to be used directly. - The uniqueness requirement is now explicit, via the `Interned` type. E.g. the pointer-based `Eq` and `Hash` comes from `Interned`, rather than via `TyS`, which wasn't obvious at all. Much of this commit is boring churn. The interesting changes are in these files: - compiler/rustc_middle/src/arena.rs - compiler/rustc_middle/src/mir/visit.rs - compiler/rustc_middle/src/ty/context.rs - compiler/rustc_middle/src/ty/mod.rs Specifically: - Most mentions of `TyS` are removed. It's very much a dumb struct now; `Ty` has all the smarts. - `TyS` now has `crate` visibility instead of `pub`. - `TyS::make_for_test` is removed in favour of the static `BOOL_TY`, which just works better with the new structure. - The `Eq`/`Ord`/`Hash` impls are removed from `TyS`. `Interned`s impls of `Eq`/`Hash` now suffice. `Ord` is now partly on `Interned` (pointer-based, for the `Equal` case) and partly on `TyS` (contents-based, for the other cases). - There are many tedious sigil adjustments, i.e. adding or removing `*` or `&`. They seem to be unavoidable.

Remove `NullOp::Box` Follow up of #89030 and MCP rust-lang/compiler-team#460. ~1 month later nothing seems to be broken, apart from a small regression that #89332 (1aac85bb716c09304b313d69d30d74fe7e8e1a8e) shows could be regained by remvoing the diverging path, so it shall be safe to continue and remove `NullOp::Box` completely. r? `@jonas-schievink` `@rustbot` label T-compiler
