2022-12-01	rustc_ast_lowering: Stop lowering imports into multiple items	Vadim Petrochenkov	-22/+22
	Lower them into a single item with multiple resolutions instead. This also allows to remove additional `NodId`s and `DefId`s related to those additional items.
2022-11-23	Separate lifetime ident from resolution in HIR.	Camille GILLOT	-4/+4

2022-11-13	Store a LocalDefId in hir::Variant & hir::Field.	Camille GILLOT	-5/+5

2022-11-13	Store a LocalDefId in hir::AnonConst.	Camille GILLOT	-16/+16

2022-10-10	Rename AssocItemKind::TyAlias to AssocItemKind::Type	Michael Goulet	-2/+2

2022-09-30	Rollup merge of #102495 - nnethercote:reinstate-hir-stats, r=lqd	Matthias Krüger	-1/+0
	Reinstate `hir-stats.rs` test for stage 1. It was disabled in #94075 for stage 1 because that PR changed type layouts such that the results for this test were different for stage 1 and stage 2. But now that #94075 is in beta, the results for this test are now the same for stage 1 and stage 2. r? ```@lqd```

2022-09-29	Shrink `hir::def::Res`.	Nicholas Nethercote	-46/+46
	`Res::SelfTy` currently has two `Option`s. When the second one is `Some` the first one is never consulted. So we can split it into two variants, `Res::SelfTyParam` and `Res::SelfTyAlias`, reducing the size of `Res` from 24 bytes to 12. This then shrinks `hir::Path` and `hir::PathSegment`, which are the HIR types that take up the most space.
2022-09-27	Bless stats.	Camille GILLOT	-6/+6

2022-09-08	Introduce `DotDotPos`.	Nicholas Nethercote	-12/+12
	This shrinks `hir::Pat` from 88 to 72 bytes.
2022-09-08	Arena-allocate `hir::Lifetime`.	Nicholas Nethercote	-34/+35
	This shrinks `hir::Ty` from 72 to 48 bytes. `visit_lifetime` is added to the HIR stats collector because these types are now stored in memory on their own, instead of being within other types.
2022-09-07	Use niche-filling optimization even when multiple variants have data.	Michael Benfield	-22/+23
	Fixes #46213
2022-09-05	use `propagate_through_exprs` instead of `propagate_through_expr`	Takayuki Maeda	-22/+22
	fix `ExprKind` static_assert_size fix hir-stats
2022-08-29	Improve HIR stats collector.	Nicholas Nethercote	-20/+52
	Adds and removes some `visit_*` methods accordingly, improving coverage, and avoiding some double counting. Brings it in line with the AST stats collector.
2022-08-29	Add prefix to every line of `-Zhir-stats` output.	Nicholas Nethercote	-151/+145
	This is based on `-Zprint-type-sizes` which does the same thing. It makes the output provenance clearer, and helps with post-processing. E.g. if you have `-Zhir-stats` output from numerous compiler invocations you can now easily extract the pre-expansion stats separately from the post-expansion stats.
2022-08-22	Use `AttrVec` in more places.	Nicholas Nethercote	-67/+67
	In some places we use `Vec<Attribute>` and some places we use `ThinVec<Attribute>` (a.k.a. `AttrVec`). This results in various points where we have to convert between `Vec` and `ThinVec`. This commit changes the places that use `Vec<Attribute>` to use `AttrVec`. A lot of this is mechanical and boring, but there are some interesting parts: - It adds a few new methods to `ThinVec`. - It implements `MapInPlace` for `ThinVec`, and introduces a macro to avoid the repetition of this trait for `Vec`, `SmallVec`, and `ThinVec`. Overall, it makes the code a little nicer, and has little effect on performance. But it is a precursor to removing `rustc_data_structures::thin_vec::ThinVec` and replacing it with `thin_vec::ThinVec`, which is implemented more efficiently.
2022-08-17	Box the `MacCall` in various types.	Nicholas Nethercote	-55/+55

2022-08-16	Shrink `ast::Attribute`.	Nicholas Nethercote	-100/+100

2022-08-11	Add a second level to the AST size reporting.	Nicholas Nethercote	-2/+62
	This tells you which variants of the enums are most common, which is very useful. I've only done it for the AST for now, HIR can be done later.
2022-08-11	Add percentages to `-Zhir-stats` output.	Nicholas Nethercote	-70/+70

2022-08-11	Change how `AssocItem` is reported.	Nicholas Nethercote	-4/+2
	Currently it's reported as either `TraitItem` or `ImplItem`. This commit changes it to `AssocItem`, because having the report match the type name is (a) consistent with other types, and (b) the trait/impl split isn't that important here.
2022-08-11	Improve AST stat collector.	Nicholas Nethercote	-5/+15
	This commit: - Adds a comment explaining which `visit_` methods should be implemented. - Adds and removes some `visit_` methods accordingly, improving coverage, and avoiding some double counting.
2022-08-11	Add a test for `-Zhir-stats` output.	Nicholas Nethercote	-0/+124
	This will be very useful in subsequent commits where I will improve the output.
