- Extract core StringPrototypeRepeat code into a TFS builtin (StringRepeat) - Assumes arguments are a string and smi (no range checks) - Add StringPrototypePadStart and StringPrototypePadEnd TFJ builtins - Added StringPadAssembler to ensure common behavior - Removed functionality from string.js A quick benchmark shows significant performance gains for unoptimized code (2.1x to 2.46x) and optimized code (1.03x - 1.56x). https: //github.com/peterwmwong/v8-perf/blob/master/string-pad/README.md Bug: v8:5049 Change-Id: I6e4fe99fb62a3edb3d6906fd4f78b3576b5b0d13 Reviewed-on: https://chromium-review.googlesource.com/720067 Commit-Queue: Jakob Gruber <jgruber@chromium.org> Reviewed-by: Jakob Gruber <jgruber@chromium.org> Cr-Commit-Position: refs/heads/master@{#48595} |
