bors 386025117a Auto merge of #110410 - saethlin:hash-u128-as-u64s, r=oli-obk ... Implement StableHasher::write_u128 via write_u64 In https://github.com/rust-lang/rust/pull/110367#issuecomment-1510114777 the cachegrind diffs indicate that nearly all the regression is from this: ``` 22,892,558 ???:<rustc_data_structures::sip128::SipHasher128>::slice_write_process_buffer -9,502,262 ???:<rustc_data_structures::sip128::SipHasher128>::short_write_process_buffer::<8> ``` Which happens because the diff for that perf run swaps a `Hash::hash` of a `u64` to a `u128`. But `slice_write_process_buffer` is a `#[cold]` function, and is for handling hashes of arbitrary-length byte arrays. Using the much more optimizer-friendly `u64` path twice to hash a `u128` provides a nice perf boost in some benchmarks.		2023-04-18 03:11:18 +00:00
