Ben Shi 5aeecc4530 cmd/compile: optimize arm64's code with more shifted operations This CL optimizes arm64's NEG/MVN/TST/CMN with a shifted operand. 1. The total size of pkg/android_arm64 decreases about 0.2KB, excluding cmd/compile/ . 2. The go1 benchmark shows no regression, excluding noise. name old time/op new time/op delta BinaryTree17-4 16.4s ± 1% 16.4s ± 1% ~ (p=0.914 n=29+29) Fannkuch11-4 8.72s ± 0% 8.72s ± 0% ~ (p=0.274 n=30+29) FmtFprintfEmpty-4 174ns ± 0% 174ns ± 0% ~ (all equal) FmtFprintfString-4 370ns ± 0% 370ns ± 0% ~ (all equal) FmtFprintfInt-4 419ns ± 0% 419ns ± 0% ~ (all equal) FmtFprintfIntInt-4 672ns ± 1% 675ns ± 2% ~ (p=0.217 n=28+30) FmtFprintfPrefixedInt-4 806ns ± 0% 806ns ± 0% ~ (p=0.402 n=30+28) FmtFprintfFloat-4 1.09µs ± 0% 1.09µs ± 0% +0.02% (p=0.011 n=22+27) FmtManyArgs-4 2.67µs ± 0% 2.68µs ± 0% ~ (p=0.279 n=29+30) GobDecode-4 33.1ms ± 1% 33.1ms ± 0% ~ (p=0.052 n=28+29) GobEncode-4 29.6ms ± 0% 29.6ms ± 0% +0.08% (p=0.013 n=28+29) Gzip-4 1.38s ± 2% 1.39s ± 2% ~ (p=0.071 n=29+29) Gunzip-4 139ms ± 0% 139ms ± 0% ~ (p=0.265 n=29+29) HTTPClientServer-4 789µs ± 4% 785µs ± 4% ~ (p=0.206 n=29+28) JSONEncode-4 49.7ms ± 0% 49.6ms ± 0% -0.24% (p=0.000 n=30+30) JSONDecode-4 266ms ± 1% 267ms ± 1% +0.34% (p=0.000 n=30+30) Mandelbrot200-4 16.6ms ± 0% 16.6ms ± 0% ~ (p=0.835 n=28+30) GoParse-4 15.9ms ± 0% 15.8ms ± 0% -0.29% (p=0.000 n=27+30) RegexpMatchEasy0_32-4 380ns ± 0% 381ns ± 0% +0.18% (p=0.000 n=30+30) RegexpMatchEasy0_1K-4 1.18µs ± 0% 1.19µs ± 0% +0.23% (p=0.000 n=30+30) RegexpMatchEasy1_32-4 357ns ± 0% 358ns ± 0% +0.28% (p=0.000 n=29+29) RegexpMatchEasy1_1K-4 2.04µs ± 0% 2.04µs ± 0% +0.06% (p=0.006 n=30+30) RegexpMatchMedium_32-4 589ns ± 0% 590ns ± 0% +0.24% (p=0.000 n=28+30) RegexpMatchMedium_1K-4 162µs ± 0% 162µs ± 0% -0.01% (p=0.027 n=26+29) RegexpMatchHard_32-4 9.58µs ± 0% 9.58µs ± 0% ~ (p=0.935 n=30+30) RegexpMatchHard_1K-4 287µs ± 0% 287µs ± 0% ~ (p=0.387 n=29+30) Revcomp-4 2.50s ± 0% 2.50s ± 0% -0.10% (p=0.020 n=28+28) Template-4 310ms ± 0% 310ms ± 1% ~ (p=0.406 n=30+30) TimeParse-4 1.68µs ± 0% 1.68µs ± 0% +0.03% (p=0.014 n=30+17) TimeFormat-4 1.65µs ± 0% 1.66µs ± 0% +0.32% (p=0.000 n=27+29) [Geo mean] 247µs 247µs +0.05% name old speed new speed delta GobDecode-4 23.2MB/s ± 0% 23.2MB/s ± 0% -0.08% (p=0.032 n=27+29) GobEncode-4 26.0MB/s ± 0% 25.9MB/s ± 0% -0.10% (p=0.011 n=29+29) Gzip-4 14.1MB/s ± 2% 14.0MB/s ± 2% ~ (p=0.081 n=29+29) Gunzip-4 139MB/s ± 0% 139MB/s ± 0% ~ (p=0.290 n=29+29) JSONEncode-4 39.0MB/s ± 0% 39.1MB/s ± 0% +0.25% (p=0.000 n=29+30) JSONDecode-4 7.30MB/s ± 1% 7.28MB/s ± 1% -0.33% (p=0.000 n=30+30) GoParse-4 3.65MB/s ± 0% 3.66MB/s ± 0% +0.29% (p=0.000 n=27+30) RegexpMatchEasy0_32-4 84.1MB/s ± 0% 84.0MB/s ± 0% -0.17% (p=0.000 n=30+28) RegexpMatchEasy0_1K-4 864MB/s ± 0% 862MB/s ± 0% -0.24% (p=0.000 n=30+30) RegexpMatchEasy1_32-4 89.5MB/s ± 0% 89.3MB/s ± 0% -0.18% (p=0.000 n=28+24) RegexpMatchEasy1_1K-4 502MB/s ± 0% 502MB/s ± 0% -0.05% (p=0.008 n=30+29) RegexpMatchMedium_32-4 1.70MB/s ± 0% 1.69MB/s ± 0% -0.59% (p=0.000 n=29+30) RegexpMatchMedium_1K-4 6.31MB/s ± 0% 6.31MB/s ± 0% +0.05% (p=0.005 n=30+26) RegexpMatchHard_32-4 3.34MB/s ± 0% 3.34MB/s ± 0% ~ (all equal) RegexpMatchHard_1K-4 3.57MB/s ± 0% 3.57MB/s ± 0% ~ (all equal) Revcomp-4 102MB/s ± 0% 102MB/s ± 0% +0.10% (p=0.022 n=28+28) Template-4 6.26MB/s ± 0% 6.26MB/s ± 1% ~ (p=0.768 n=30+30) [Geo mean] 24.2MB/s 24.1MB/s -0.08% Change-Id: I494f9db7f8a568a00e9c74ae25086a58b2221683 Reviewed-on: https://go-review.googlesource.com/137976 Run-TryBot: Ben Shi <powerman1st@163.com> TryBot-Result: Gobot Gobot <gobot@golang.org> Reviewed-by: Cherry Zhang <cherryyz@google.com>		2018-09-28 15:05:17 +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.
