Ilya Tocar 9eb219480e compress/bzip2: remove bit-tricks ... Since compiler is now able to generate conditional moves, we can replace bit-tricks with simple if/else. This even results in slightly better performance: name old time/op new time/op delta DecodeDigits-6 13.4ms ± 4% 13.0ms ± 2% -2.63% (p=0.003 n=10+10) DecodeTwain-6 37.5ms ± 1% 36.3ms ± 1% -3.03% (p=0.000 n=10+9) DecodeRand-6 4.23ms ± 1% 4.07ms ± 1% -3.67% (p=0.000 n=10+9) name old speed new speed delta DecodeDigits-6 7.47MB/s ± 4% 7.67MB/s ± 2% +2.69% (p=0.002 n=10+10) DecodeTwain-6 10.4MB/s ± 1% 10.7MB/s ± 1% +3.25% (p=0.000 n=10+8) DecodeRand-6 3.87MB/s ± 1% 4.03MB/s ± 2% +4.08% (p=0.000 n=10+10) diff --git a/src/compress/bzip2/huffman.go b/src/compress/bzip2/huffman.go Change-Id: Ie96ef1a9e07013b07e78f22cdccd531f3341caca Reviewed-on: https://go-review.googlesource.com/102015 Run-TryBot: Ilya Tocar <ilya.tocar@intel.com> Reviewed-by: Joe Tsai <joetsai@google.com> TryBot-Result: Gobot Gobot <gobot@golang.org>		2018-03-21 21:57:15 +00:00
