Eliminate bunch of copies of error codepath from Utf8LossyChunksIter Using a macro to stamp out 7 identical copies of the nontrivial slicing logic to exit this loop didn't seem like a necessary use of a macro. The early return case can be handled by `break` without practically any changes to the logic inside the loop. All this code is from early 2014 (#12062—nearly 8 years ago; pre-1.0) so it's possible there were compiler limitations that forced the macro way at the time. Confirmed that `x.py bench library/alloc --stage 0 --test-args from_utf8_lossy` is unaffected on my machine. |
