Agniva De Sarker 4a7cd9d9df internal/bytealg: simplify memchr for wasm ... Get rid of an extra register R5 which just recalculated the value of R4. Reuse R4 instead. We also remove the casting of c to an unsigned char because the initial load of R0 is done with I32Load8U anyways. Also indent the code to make it more readable. name old time/op new time/op delta IndexRune 597ns ± 3% 580ns ± 3% -2.93% (p=0.002 n=10+10) IndexRuneLongString 634ns ± 4% 654ns ± 3% +3.07% (p=0.004 n=10+10) IndexRuneFastPath 57.6ns ± 3% 56.9ns ± 4% ~ (p=0.210 n=10+10) Index 104ns ± 3% 104ns ± 4% ~ (p=0.639 n=10+10) LastIndex 87.1ns ± 5% 85.7ns ± 3% ~ (p=0.171 n=10+10) IndexByte 34.4ns ± 4% 32.9ns ± 5% -4.28% (p=0.002 n=10+10) IndexHard1 21.6ms ± 1% 21.8ms ± 3% ~ (p=0.460 n=8+10) IndexHard2 21.6ms ± 2% 21.9ms ± 5% ~ (p=0.133 n=9+10) IndexHard3 21.8ms ± 3% 21.7ms ± 1% ~ (p=0.579 n=10+10) IndexHard4 21.6ms ± 1% 21.9ms ± 4% ~ (p=0.360 n=8+10) LastIndexHard1 25.1ms ± 2% 25.4ms ± 5% ~ (p=0.853 n=10+10) LastIndexHard2 25.3ms ± 6% 25.2ms ± 5% ~ (p=0.796 n=10+10) LastIndexHard3 25.3ms ± 4% 25.2ms ± 3% ~ (p=0.739 n=10+10) IndexTorture 130µs ± 3% 133µs ± 5% ~ (p=0.218 n=10+10) IndexAnyASCII/1:1 98.4ns ± 5% 96.6ns ± 5% ~ (p=0.054 n=10+10) IndexAnyASCII/1:2 109ns ± 4% 110ns ± 3% ~ (p=0.232 n=10+10) IndexAnyASCII/1:4 135ns ± 4% 134ns ± 3% ~ (p=0.671 n=10+10) IndexAnyASCII/1:8 184ns ± 4% 184ns ± 3% ~ (p=0.749 n=10+10) IndexAnyASCII/1:16 289ns ± 3% 281ns ± 3% -2.73% (p=0.001 n=9+10) IndexAnyASCII/16:1 322ns ± 3% 307ns ± 3% -4.71% (p=0.000 n=10+10) IndexAnyASCII/16:2 329ns ± 3% 320ns ± 3% -2.89% (p=0.008 n=10+10) IndexAnyASCII/16:4 353ns ± 3% 339ns ± 3% -3.91% (p=0.001 n=10+10) IndexAnyASCII/16:8 390ns ± 3% 374ns ± 3% -4.06% (p=0.000 n=10+10) IndexAnyASCII/16:16 471ns ± 4% 452ns ± 2% -4.22% (p=0.000 n=10+10) IndexAnyASCII/256:1 2.94µs ± 4% 2.91µs ± 2% ~ (p=0.424 n=10+10) IndexAnyASCII/256:2 2.92µs ± 3% 2.90µs ± 2% ~ (p=0.388 n=9+10) IndexAnyASCII/256:4 2.93µs ± 1% 2.90µs ± 1% -0.98% (p=0.036 n=8+9) IndexAnyASCII/256:8 3.03µs ± 5% 2.97µs ± 3% ~ (p=0.085 n=10+10) IndexAnyASCII/256:16 3.07µs ± 4% 3.01µs ± 1% -2.03% (p=0.003 n=10+9) IndexAnyASCII/4096:1 45.8µs ± 3% 45.9µs ± 2% ~ (p=0.905 n=10+9) IndexAnyASCII/4096:2 46.7µs ± 3% 46.2µs ± 3% ~ (p=0.190 n=10+10) IndexAnyASCII/4096:4 45.7µs ± 2% 46.4µs ± 3% +1.37% (p=0.022 n=9+10) IndexAnyASCII/4096:8 46.4µs ± 3% 46.0µs ± 2% ~ (p=0.436 n=10+10) IndexAnyASCII/4096:16 46.6µs ± 3% 46.7µs ± 2% ~ (p=0.971 n=10+10) IndexPeriodic/IndexPeriodic2 1.40ms ± 3% 1.40ms ± 2% ~ (p=0.853 n=10+10) IndexPeriodic/IndexPeriodic4 1.40ms ± 3% 1.40ms ± 3% ~ (p=0.579 n=10+10) IndexPeriodic/IndexPeriodic8 1.42ms ± 3% 1.39ms ± 2% -1.60% (p=0.029 n=10+10) IndexPeriodic/IndexPeriodic16 616µs ± 5% 583µs ± 5% -5.32% (p=0.001 n=10+10) IndexPeriodic/IndexPeriodic32 313µs ± 5% 301µs ± 2% -3.67% (p=0.002 n=10+10) IndexPeriodic/IndexPeriodic64 169µs ± 5% 164µs ± 5% -3.17% (p=0.023 n=10+10) NodeJS version - 10.2.1 Change-Id: I9a8268314b5652c4aeffc4c5c72d2fd1a384aa9e Reviewed-on: https://go-review.googlesource.com/c/go/+/169777 Run-TryBot: Agniva De Sarker <agniva.quicksilver@gmail.com> TryBot-Result: Gobot Gobot <gobot@golang.org> Reviewed-by: Cherry Zhang <cherryyz@google.com>		2019-03-29 03:59:19 +00:00
