Ben Shi 34f5f8a580 cmd/compile: optimize ARM64 with register indexed load/store ARM64 supports load/store instructions with a memory operand that the address is calculated by base register + index register. In this CL, 1. Some rules are added to the compile's ARM64 backend to emit such efficient instructions. 2. A wrong rule of load combination is fixed. The go1 benchmark does show improvement. name old time/op new time/op delta BinaryTree17-4 44.5s ± 2% 44.1s ± 1% -0.81% (p=0.000 n=28+29) Fannkuch11-4 32.7s ± 3% 30.5s ± 0% -6.79% (p=0.000 n=30+26) FmtFprintfEmpty-4 499ns ± 0% 506ns ± 5% +1.39% (p=0.003 n=25+30) FmtFprintfString-4 1.07µs ± 0% 1.04µs ± 4% -3.17% (p=0.000 n=23+30) FmtFprintfInt-4 1.15µs ± 4% 1.13µs ± 0% -1.55% (p=0.000 n=30+23) FmtFprintfIntInt-4 1.77µs ± 4% 1.74µs ± 0% -1.71% (p=0.000 n=30+24) FmtFprintfPrefixedInt-4 2.37µs ± 5% 2.12µs ± 0% -10.56% (p=0.000 n=30+23) FmtFprintfFloat-4 3.03µs ± 1% 3.03µs ± 4% -0.13% (p=0.003 n=25+30) FmtManyArgs-4 7.38µs ± 1% 7.43µs ± 4% +0.59% (p=0.003 n=25+30) GobDecode-4 101ms ± 6% 95ms ± 5% -5.55% (p=0.000 n=30+30) GobEncode-4 78.0ms ± 4% 78.8ms ± 6% +1.05% (p=0.000 n=30+30) Gzip-4 4.25s ± 0% 4.27s ± 4% +0.45% (p=0.003 n=24+30) Gunzip-4 428ms ± 1% 420ms ± 0% -1.88% (p=0.000 n=23+23) HTTPClientServer-4 549µs ± 1% 541µs ± 1% -1.56% (p=0.000 n=29+29) JSONEncode-4 194ms ± 0% 188ms ± 4% ~ (p=0.417 n=23+30) JSONDecode-4 890ms ± 5% 831ms ± 0% -6.55% (p=0.000 n=30+23) Mandelbrot200-4 47.3ms ± 2% 46.5ms ± 0% ~ (p=0.980 n=30+26) GoParse-4 43.1ms ± 6% 43.8ms ± 6% +1.65% (p=0.000 n=30+30) RegexpMatchEasy0_32-4 1.06µs ± 0% 1.07µs ± 3% ~ (p=0.092 n=23+30) RegexpMatchEasy0_1K-4 5.53µs ± 0% 5.51µs ± 0% -0.24% (p=0.000 n=25+25) RegexpMatchEasy1_32-4 1.02µs ± 3% 1.01µs ± 0% -1.27% (p=0.000 n=30+24) RegexpMatchEasy1_1K-4 7.26µs ± 0% 7.33µs ± 0% +0.95% (p=0.000 n=23+26) RegexpMatchMedium_32-4 1.84µs ± 7% 1.79µs ± 1% ~ (p=0.333 n=30+23) RegexpMatchMedium_1K-4 553µs ± 0% 547µs ± 0% -1.14% (p=0.000 n=24+22) RegexpMatchHard_32-4 30.8µs ± 1% 30.3µs ± 0% -1.40% (p=0.000 n=24+24) RegexpMatchHard_1K-4 928µs ± 0% 929µs ± 5% +0.12% (p=0.013 n=23+30) Revcomp-4 8.13s ± 4% 6.32s ± 1% -22.23% (p=0.000 n=30+23) Template-4 899ms ± 6% 854ms ± 1% -5.01% (p=0.000 n=30+24) TimeParse-4 4.66µs ± 4% 4.59µs ± 1% -1.57% (p=0.000 n=30+23) TimeFormat-4 4.58µs ± 0% 4.61µs ± 0% +0.57% (p=0.000 n=26+24) [Geo mean] 717µs 698µs -2.55% name old speed new speed delta GobDecode-4 7.63MB/s ± 6% 8.08MB/s ± 5% +5.88% (p=0.000 n=30+30) GobEncode-4 9.85MB/s ± 4% 9.75MB/s ± 6% -1.04% (p=0.000 n=30+30) Gzip-4 4.56MB/s ± 0% 4.55MB/s ± 4% -0.36% (p=0.003 n=24+30) Gunzip-4 45.3MB/s ± 1% 46.2MB/s ± 0% +1.92% (p=0.000 n=23+23) JSONEncode-4 10.0MB/s ± 0% 10.4MB/s ± 4% ~ (p=0.403 n=23+30) JSONDecode-4 2.18MB/s ± 5% 2.33MB/s ± 0% +6.91% (p=0.000 n=30+23) GoParse-4 1.34MB/s ± 5% 1.32MB/s ± 5% -1.66% (p=0.000 n=30+30) RegexpMatchEasy0_32-4 30.2MB/s ± 0% 29.8MB/s ± 3% ~ (p=0.099 n=23+30) RegexpMatchEasy0_1K-4 185MB/s ± 0% 186MB/s ± 0% +0.24% (p=0.000 n=25+25) RegexpMatchEasy1_32-4 31.4MB/s ± 3% 31.8MB/s ± 0% +1.24% (p=0.000 n=30+24) RegexpMatchEasy1_1K-4 141MB/s ± 0% 140MB/s ± 0% -0.94% (p=0.000 n=23+26) RegexpMatchMedium_32-4 541kB/s ± 6% 560kB/s ± 0% +3.45% (p=0.000 n=30+23) RegexpMatchMedium_1K-4 1.85MB/s ± 0% 1.87MB/s ± 0% +1.08% (p=0.000 n=24+23) RegexpMatchHard_32-4 1.04MB/s ± 1% 1.06MB/s ± 1% +1.48% (p=0.000 n=24+24) RegexpMatchHard_1K-4 1.10MB/s ± 0% 1.10MB/s ± 5% +0.15% (p=0.004 n=23+30) Revcomp-4 31.3MB/s ± 4% 40.2MB/s ± 1% +28.52% (p=0.000 n=30+23) Template-4 2.16MB/s ± 6% 2.27MB/s ± 1% +5.18% (p=0.000 n=30+24) [Geo mean] 7.57MB/s 7.79MB/s +2.98% fixes #24907 Change-Id: I94afd0e3f53d62a1cf5e452f3dd6daf61be21785 Reviewed-on: https://go-review.googlesource.com/107376 Run-TryBot: Cherry Zhang <cherryyz@google.com> TryBot-Result: Gobot Gobot <gobot@golang.org> Reviewed-by: Cherry Zhang <cherryyz@google.com>		2018-04-19 15:08:10 +00:00

README.md

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.
