bors 86bd45979a Auto merge of #130223 - LaihoE:faster_str_replace, r=thomcc ... optimize str.replace Adds a fast path for str.replace for the ascii to ascii case. This allows for autovectorizing the code. Also should this instead be done with specialization? This way we could remove one branch. I think it is the kind of branch that is easy to predict though. Benchmark for the fast path (replace all "a" with "b" in the rust wikipedia article, using criterion) : | N | Speedup | Time New (ns) | Time Old (ns) | |----------|---------|---------------|---------------| | 2 | 2.03 | 13.567 | 27.576 | | 8 | 1.73 | 17.478 | 30.259 | | 11 | 2.46 | 18.296 | 45.055 | | 16 | 2.71 | 17.181 | 46.526 | | 37 | 4.43 | 18.526 | 81.997 | | 64 | 8.54 | 18.670 | 159.470 | | 200 | 9.82 | 29.634 | 291.010 | | 2000 | 24.34 | 81.114 | 1974.300 | | 20000 | 30.61 | 598.520 | 18318.000 | | 1000000 | 29.31 | 33458.000 | 980540.000 |		2024-10-17 16:20:02 +00:00
