	The previous commit updated `rustfmt.toml` appropriately. This commit is the outcome of running `x fmt --all` with the new formatting options.

2023-11-27	rustc_span: Use correct edit distance start length for suggestions	Martin Nordholts	-1/+5
	Otherwise the suggestions can be off-base for non-ASCII identifiers. For example suggesting that `Ok` is a name similar to `读文`.
2023-08-04	Rollup merge of #114351 - ttsugriy:sort-by-words, r=fee1-dead	Matthias Krüger	-2/+2
	[rustc_span][perf] Remove unnecessary string joins and allocs. Comparing vectors of string parts yields the same result but avoids unnecessary `join` and potential allocation for resulting `String`. This code is cold so it's unlikely to have any measurable impact, but considering but since it's also simpler, why not? :)
2023-08-02	[rustc_span][perf] Hoist lookup sorted by words out of the loop.	Taras Tsugrii	-1/+2
	@lqd commented on https://github.com/rust-lang/rust/pull/114351 asking if `sort_by_words(lookup)` is computed repeatedly. I was assuming that rustc should have no difficulties to hoist it automatically outside of the loop to avoid repeated pure computation, but according to https://godbolt.org/z/frs8Kj1rq it seems like I was wrong: original version seems to have 2 calls per loop iteration ``` .LBB16_3: mov rbx, qword ptr [r13] mov r14, qword ptr [r13 + 8] lea rdi, [rsp + 40] mov rsi, rbx mov rdx, r14 call example::sort_by_words lea rdi, [rsp + 64] mov rsi, qword ptr [rsp + 8] mov rdx, qword ptr [rsp + 16] call example::sort_by_words mov rdi, qword ptr [rsp + 40] mov rdx, qword ptr [rsp + 56] mov rsi, qword ptr [rsp + 64] cmp rdx, qword ptr [rsp + 80] mov qword ptr [rsp + 32], rdi mov qword ptr [rsp + 24], rsi jne .LBB16_5 call qword ptr [rip + bcmp@GOTPCREL] test eax, eax sete al mov dword ptr [rsp + 4], eax mov rsi, qword ptr [rsp + 72] test rsi, rsi jne .LBB16_8 jmp .LBB16_9 ``` but the manually hoisted version just 1: ``` .LBB16_3: mov r13, qword ptr [r15] mov r14, qword ptr [r15 + 8] lea rdi, [rsp + 64] mov rsi, r13 mov rdx, r14 call example::sort_by_words mov rdi, qword ptr [rsp + 64] mov rdx, qword ptr [rsp + 16] cmp qword ptr [rsp + 80], rdx mov qword ptr [rsp + 32], rdi jne .LBB16_5 mov rsi, qword ptr [rsp + 8] call qword ptr [rip + bcmp@GOTPCREL] test eax, eax sete bpl mov rsi, qword ptr [rsp + 72] test rsi, rsi jne .LBB16_8 jmp .LBB16_9 ``` This code is probably not very hot, but there is no reason to leave such a low hanging fruit.
