2023-12-25Auto merge of #119226 - Mark-Simulacrum:format-efficiency, r=TaKO8Kibors-23/+36
Improve coding efficiency for RawDefId This copies the scheme already used for LazyArray, cutting a couple hundred kilobytes from libcore's metadata.
2023-12-23Specialize DefPathHash table to skip crate IDsMark Rousskov-23/+0
Instead, we store just the local crate hash as a bare u64. On decoding, we recombine it with the crate's stable crate ID stored separately in metadata. The end result is that we save ~8 bytes/DefIndex in metadata size. One key detail here is that we no longer distinguish in encoded metadata between present and non-present DefPathHashes. It used to be highly likely we could distinguish as we used DefPathHash::default(), an all-zero representation. However in theory even that is fallible as nothing strictly prevents the StableCrateId from being zero.

Adapt table sizes to the contents This is an implementation of https://github.com/rust-lang/compiler-team/issues/666 The objective of this PR is to permit the rmeta format to accommodate larger crates that need offsets larger than a `u32` can store without compromising performance for crates that do not need such range. The second commit is a number of tiny optimization opportunities I noticed while looking at perf recordings of the first commit. The rmeta tables need to have fixed-size elements to permit lazy random access. But the size only needs to be fixed _per table_, not per element type. This PR adds another `usize` to the table header which indicates the table element size. As each element of a table is set, we keep track of the widest encoded table value, then don't bother encoding all the unused trailing bytes on each value. When decoding table elements, we copy them to a full-width array if they are not already full-width. `LazyArray` needs some special treatment. Most other values that are encoded in tables are indexes or offsets, and those tend to be small so we get to drop a lot of zero bytes off the end. But `LazyArray` encodes _two_ small values in a fixed-width table element: A position of the table and the length of the table. The treatment described above could trim zero bytes off the table length, but any nonzero length shields the position bytes from the optimization. To improve this, we interleave the bytes of position and length. This change is responsible for about half of the crate metadata win on many crates.

2023-02-05rustc_metadata: Refactor lazy table reading/writingVadim Petrochenkov-33/+80
Change wording from "nullable" to "default". Introduce a trait `IsDefault` for detecting values that are encoded as zeros or not encoded at all. Add panics to impossible cases. Some other minor cleanups.
2023-01-23rustc_metadata: Support non-`Option` nullable values in metadata tablesVadim Petrochenkov-42/+30
This is a convenience feature for cases in which "no value in the table" and "default value in the table" are equivalent. Tables using `Table<DefIndex, ()>` are migrated in this PR, some other cases can be migrated later. This helps `DocFlags` in https://github.com/rust-lang/rust/pull/107136 in particular.
2023-01-21rustc_metadata: Encode `doc(hidden)` flag to metadataVadim Petrochenkov-0/+14
To retrieve these flags rustdoc currently has to mass decode full attributes for items in the whole crate tree, so it's better to pre-compute it in advance. This is especially for short-term performance of https://github.com/rust-lang/rust/pull/107054 because resolver cannot use memoization of query results yet.

Remove EntryKind from metadata. This PR continues the refactor of metadata emission to be more systematic, iterating on definitions and filtering based on each definition's `DefKind`. This allows to remove the large `EntryKind` enum, replaced by linear tables in metadata.
