The SUBL instruction can take a memory operand, and this CL implements this optimization. The go1 benchmark shows a little improvement. name old time/op new time/op delta BinaryTree17-4 3.27s ± 2% 3.29s ± 3% ~ (p=0.322 n=37+40) Fannkuch11-4 3.49s ± 0% 3.53s ± 1% +1.21% (p=0.000 n=31+40) FmtFprintfEmpty-4 46.2ns ± 3% 46.3ns ± 2% ~ (p=0.351 n=40+28) FmtFprintfString-4 82.0ns ± 3% 81.5ns ± 2% -0.69% (p=0.002 n=40+30) FmtFprintfInt-4 94.6ns ± 3% 94.6ns ± 6% ~ (p=0.913 n=39+37) FmtFprintfIntInt-4 147ns ± 3% 150ns ± 2% +1.72% (p=0.000 n=40+25) FmtFprintfPrefixedInt-4 186ns ± 3% 186ns ± 0% -0.33% (p=0.006 n=40+25) FmtFprintfFloat-4 388ns ± 4% 388ns ± 4% ~ (p=0.162 n=40+40) FmtManyArgs-4 612ns ± 3% 616ns ± 4% ~ (p=0.223 n=40+40) GobDecode-4 7.35ms ± 5% 7.42ms ± 5% ~ (p=0.095 n=40+40) GobEncode-4 7.21ms ± 8% 7.23ms ± 4% ~ (p=0.294 n=40+40) Gzip-4 360ms ± 4% 359ms ± 4% ~ (p=0.097 n=40+40) Gunzip-4 46.1ms ± 3% 45.6ms ± 3% -1.20% (p=0.000 n=40+40) HTTPClientServer-4 64.0µs ± 2% 64.1µs ± 2% ~ (p=0.648 n=39+40) JSONEncode-4 21.9ms ± 4% 22.1ms ± 5% ~ (p=0.086 n=40+40) JSONDecode-4 67.9ms ± 4% 66.7ms ± 4% -1.63% (p=0.000 n=40+40) Mandelbrot200-4 5.19ms ± 3% 5.17ms ± 3% ~ (p=0.881 n=40+40) GoParse-4 3.34ms ± 3% 3.28ms ± 2% -1.78% (p=0.000 n=40+40) RegexpMatchEasy0_32-4 101ns ± 5% 99ns ± 3% -2.40% (p=0.000 n=40+40) RegexpMatchEasy0_1K-4 851ns ± 1% 848ns ± 3% -0.36% (p=0.004 n=33+40) RegexpMatchEasy1_32-4 109ns ± 5% 105ns ± 3% -3.53% (p=0.000 n=39+40) RegexpMatchEasy1_1K-4 1.03µs ± 4% 1.03µs ± 3% ~ (p=0.638 n=40+38) RegexpMatchMedium_32-4 131ns ± 5% 127ns ± 4% -3.36% (p=0.000 n=38+40) RegexpMatchMedium_1K-4 43.4µs ± 4% 43.2µs ± 3% -0.46% (p=0.008 n=40+40) RegexpMatchHard_32-4 2.21µs ± 4% 2.23µs ± 1% +0.77% (p=0.014 n=40+28) RegexpMatchHard_1K-4 67.6µs ± 4% 67.7µs ± 3% +0.11% (p=0.016 n=40+40) Revcomp-4 1.86s ± 3% 1.77s ± 2% -4.81% (p=0.000 n=40+40) Template-4 71.7ms ± 3% 71.6ms ± 4% ~ (p=0.200 n=40+40) TimeParse-4 436ns ± 4% 433ns ± 3% ~ (p=0.358 n=40+40) TimeFormat-4 413ns ± 4% 412ns ± 3% ~ (p=0.415 n=40+40) [Geo mean] 63.9µs 63.6µs -0.49% name old speed new speed delta GobDecode-4 105MB/s ± 5% 104MB/s ± 5% ~ (p=0.096 n=40+40) GobEncode-4 106MB/s ± 7% 106MB/s ± 3% ~ (p=0.385 n=39+40) Gzip-4 54.0MB/s ± 4% 54.0MB/s ± 4% ~ (p=0.100 n=40+40) Gunzip-4 421MB/s ± 3% 426MB/s ± 3% +1.21% (p=0.000 n=40+40) JSONEncode-4 88.5MB/s ± 5% 88.0MB/s ± 5% ~ (p=0.083 n=40+40) JSONDecode-4 28.6MB/s ± 4% 29.1MB/s ± 4% +1.65% (p=0.000 n=40+40) GoParse-4 17.3MB/s ± 3% 17.7MB/s ± 2% +1.82% (p=0.000 n=40+40) RegexpMatchEasy0_32-4 316MB/s ± 5% 323MB/s ± 4% +2.44% (p=0.000 n=40+40) RegexpMatchEasy0_1K-4 1.20GB/s ± 1% 1.21GB/s ± 3% +0.40% (p=0.004 n=33+40) RegexpMatchEasy1_32-4 291MB/s ± 7% 302MB/s ± 4% +3.82% (p=0.000 n=40+40) RegexpMatchEasy1_1K-4 993MB/s ± 4% 990MB/s ± 3% ~ (p=0.623 n=40+38) RegexpMatchMedium_32-4 7.61MB/s ± 5% 7.87MB/s ± 4% +3.36% (p=0.000 n=38+40) RegexpMatchMedium_1K-4 23.6MB/s ± 4% 23.7MB/s ± 4% +0.46% (p=0.007 n=40+40) RegexpMatchHard_32-4 14.5MB/s ± 4% 14.3MB/s ± 1% -0.79% (p=0.017 n=40+28) RegexpMatchHard_1K-4 15.1MB/s ± 4% 15.1MB/s ± 3% -0.11% (p=0.015 n=40+40) Revcomp-4 137MB/s ± 3% 144MB/s ± 3% +5.06% (p=0.000 n=40+40) Template-4 27.1MB/s ± 3% 27.1MB/s ± 4% ~ (p=0.211 n=40+40) [Geo mean] 78.9MB/s 79.7MB/s +1.01% Change-Id: I638fa4fef85833e8605919d693f9570cc3cf7334 Reviewed-on: https://go-review.googlesource.com/107275 Run-TryBot: Keith Randall <khr@golang.org> TryBot-Result: Gobot Gobot <gobot@golang.org> Reviewed-by: Keith Randall <khr@golang.org> |

The test directory contains tests of the Go tool chain and runtime. It includes black box tests, regression tests, and error output tests. They are run as part of all.bash.
To run just these tests, execute:
../bin/go run run.go
Standard library tests should be written as regular Go tests in the appropriate package.
The tool chain and runtime also have regular Go tests in their packages. The main reasons to add a new test to this directory are:
- it is most naturally expressed using the test runner; or
- it is also applicable to
gccgo
and other Go tool chains.
