There was a problem hiding this comment.
The changes in this PR seems to be causing some noticeable regressions across multiple benchmark runs for fill() as seen in these benchmark results for example:
buffers/buffer-fill.js n=20000 size=8192 type='fill(0)' *** -31.61 % ±5.72% ±7.65% ±10.04%
buffers/buffer-fill.js n=20000 size=8192 type='fill(100)' *** -31.92 % ±3.21% ±4.28% ±5.59%
buffers/buffer-fill.js n=20000 size=8192 type='fill(400)' *** -32.13 % ±4.27% ±5.69% ±7.43%
buffers/buffer-fill.js n=20000 size=8192 type='fill("t", 0, "utf8")' *** -9.67 % ±5.14% ±6.84% ±8.90%
buffers/buffer-fill.js n=20000 size=8192 type='fill("t", "utf8")' *** -11.96 % ±5.80% ±7.71% ±10.05%
