Tobias Klauser 08e1823a63 bytes: optimize ToLower and ToUpper for ASCII-only case ... Follow what CL 68370 and CL 76470 did for the respective functions in package strings. Also adjust godoc strings to match the respective strings functions and mention the special case for ASCII-only byte slices which don't need conversion. name old time/op new time/op delta ToUpper/#00-8 9.35ns ± 3% 6.08ns ± 2% -35.04% (p=0.000 n=9+9) ToUpper/ONLYUPPER-8 77.7ns ± 1% 16.9ns ± 2% -78.22% (p=0.000 n=10+10) ToUpper/abc-8 36.5ns ± 1% 22.1ns ± 1% -39.43% (p=0.000 n=10+8) ToUpper/AbC123-8 56.9ns ± 2% 28.2ns ± 2% -50.54% (p=0.000 n=8+10) ToUpper/azAZ09_-8 62.3ns ± 1% 26.9ns ± 1% -56.82% (p=0.000 n=9+10) ToUpper/longStrinGwitHmixofsmaLLandcAps-8 219ns ± 2% 63ns ± 2% -71.17% (p=0.000 n=10+10) ToUpper/longɐstringɐwithɐnonasciiⱯchars-8 367ns ± 2% 374ns ± 3% +2.05% (p=0.000 n=9+10) ToUpper/ɐɐɐɐɐ-8 200ns ± 1% 206ns ± 1% +2.49% (p=0.000 n=10+10) ToUpper/a\u0080\U0010ffff-8 90.4ns ± 1% 93.8ns ± 0% +3.82% (p=0.000 n=10+7) ToLower/#00-8 9.59ns ± 1% 6.13ns ± 2% -36.08% (p=0.000 n=10+10) ToLower/abc-8 36.4ns ± 1% 10.4ns ± 1% -71.50% (p=0.000 n=10+10) ToLower/AbC123-8 55.8ns ± 1% 27.5ns ± 1% -50.61% (p=0.000 n=10+10) ToLower/azAZ09_-8 61.7ns ± 1% 30.2ns ± 1% -50.98% (p=0.000 n=8+10) ToLower/longStrinGwitHmixofsmaLLandcAps-8 226ns ± 1% 64ns ± 1% -71.53% (p=0.000 n=10+9) ToLower/LONGⱯSTRINGⱯWITHⱯNONASCIIⱯCHARS-8 354ns ± 0% 361ns ± 0% +2.18% (p=0.000 n=10+10) ToLower/ⱭⱭⱭⱭⱭ-8 180ns ± 1% 186ns ± 0% +3.45% (p=0.000 n=10+9) ToLower/A\u0080\U0010ffff-8 91.7ns ± 0% 94.5ns ± 0% +2.99% (p=0.000 n=10+10) Change-Id: Ifdb8ae328ff9feacd1c170db8eebbf98c399e204 Reviewed-on: https://go-review.googlesource.com/c/go/+/170954 Run-TryBot: Tobias Klauser <tobias.klauser@gmail.com> TryBot-Result: Gobot Gobot <gobot@golang.org> Reviewed-by: Keith Randall <khr@golang.org>		2019-04-09 05:45:34 +00:00
