* Merge #8364bors[bot]2021-04-062-4/+10
|\ | | | | | | | | | | | | | | | | | | 8364: Memory usage improvements r=jonas-schievink a=alexmaco These are mostly focused on splitting up enum variants with large size differences between variants by `Box`-ing things up. In my testing this reduces the memory usage somewhere in the low percentages, even though the measurements are quite noisy. Co-authored-by: Alexandru Macovei <[email protected]>
| * Use Box'es to reduce the size of hir_def::expr::Pat from 112 to 64 bytes on ↵Alexandru Macovei2021-04-061-2/+2
| | | | | | | | 64bit
| * Use Box'es to reduce size of hir_def::expr::Expr from 128 to 72 bytes (on ↵Alexandru Macovei2021-04-061-2/+8
| | | | | | | | | | | | | | | | | | | | 64bit systems) Rationale: only a minority of variants used almost half the size. By keeping large members (especially in Option) behind a box the memory cost is only payed when the large variants are needed. This reduces the size Vec<Expr> needs to allocate.

* Fix shifting of binders in FnPointerFlorian Diebold2021-04-054-10/+23
| | | | | | | | | - don't shift in/out for Chalk mapping (we want to have the same binders now) - do shift in when creating the signature for a closure (though it shouldn't matter much) - do shift in when lowering a `fn()` type - correctly deal with the implied binder in TypeWalk
* Align FnPointer with ChalkFlorian Diebold2021-04-059-40/+86

|\ | | | | | | | | | | | | | | 8353: Replace hir_ty::Lifetime with chalk equivalent r=flodiebold a=Veykril Our `Lifetime` isn't really used yet so this is a rather simple change Co-authored-by: Lukas Wirth <[email protected]>

| | | | Saves ~3 MB
* Move things from `traits` module to `types` as wellFlorian Diebold2021-04-0411-107/+103
|
* Move things in hir_ty into submodulesFlorian Diebold2021-04-0410-706/+750
| | | | | - all the types that will be replaced by Chalk go to `types` - `TypeWalk` impls go to `walk`
