2025-06-30	Introduce `ByteSymbol`.	Nicholas Nethercote	-6/+6
	It's like `Symbol` but for byte strings. The interner is now used for both `Symbol` and `ByteSymbol`. E.g. if you intern `"dog"` and `b"dog"` you'll get a `Symbol` and a `ByteSymbol` with the same index and the characters will only be stored once. The motivation for this is to eliminate the `Arc`s in `ast::LitKind`, to make `ast::LitKind` impl `Copy`, and to avoid the need to arena-allocate `ast::LitKind` in HIR. The latter change reduces peak memory by a non-trivial amount on literal-heavy benchmarks such as `deep-vector` and `tuple-stress`. `Encoder`, `Decoder`, `SpanEncoder`, and `SpanDecoder` all get some changes so that they can handle normal strings and byte strings. This change does slow down compilation of programs that use `include_bytes!` on large files, because the contents of those files are now interned (hashed). This makes `include_bytes!` more similar to `include_str!`, though `include_bytes!` contents still aren't escaped, and hashing is still much cheaper than escaping.
2025-04-10	Allow drivers to supply a list of extra symbols to intern	Alex Macleod	-1/+1

2024-07-29	Reformat `use` declarations.	Nicholas Nethercote	-1/+0
	The previous commit updated `rustfmt.toml` appropriately. This commit is the outcome of running `x fmt --all` with the new formatting options.
2023-11-03	Use `FxIndexSet` in the symbol interner.	Nicholas Nethercote	-1/+1
	It makes the code a little nicer. As part of this, the interner's `Default` impl is removed and `prefill` is used in a test instead.
2021-09-15	Move the Lock into symbol::Interner	bjorn3	-1/+1
	This makes it easier to make the symbol interner (near) lock free in case of concurrent accesses in the future.
2021-07-08	Rework SESSION_GLOBALS API to prevent overwriting it	Guillaume Gomez	-2/+2

2020-08-30	mv compiler to compiler/	mark	-0/+25
