Ben Shi 031a35ec84 cmd/compile: optimize 386's comparison Optimization of "(CMPconst [0] (ANDL x y)) -> (TESTL x y)" only get benefits if there is no further use of the result of x&y. A condition of uses==1 will have slight improvements. 1. The code size of pkg/linux_386 decreases about 300 bytes, excluding cmd/compile/. 2. The go1 benchmark shows no regression, and even a slight improvement in test case FmtFprintfEmpty-4, excluding noise. name old time/op new time/op delta BinaryTree17-4 3.34s ± 3% 3.32s ± 2% ~ (p=0.197 n=30+30) Fannkuch11-4 3.48s ± 2% 3.47s ± 1% -0.33% (p=0.015 n=30+30) FmtFprintfEmpty-4 46.3ns ± 4% 44.8ns ± 4% -3.33% (p=0.000 n=30+30) FmtFprintfString-4 78.8ns ± 7% 77.3ns ± 5% ~ (p=0.098 n=30+26) FmtFprintfInt-4 90.2ns ± 1% 90.0ns ± 7% -0.23% (p=0.027 n=18+30) FmtFprintfIntInt-4 144ns ± 4% 143ns ± 5% ~ (p=0.945 n=30+29) FmtFprintfPrefixedInt-4 180ns ± 4% 180ns ± 5% ~ (p=0.858 n=30+30) FmtFprintfFloat-4 409ns ± 4% 406ns ± 3% -0.87% (p=0.028 n=30+30) FmtManyArgs-4 611ns ± 5% 608ns ± 4% ~ (p=0.812 n=30+30) GobDecode-4 7.30ms ± 5% 7.26ms ± 5% ~ (p=0.522 n=30+29) GobEncode-4 6.90ms ± 7% 6.82ms ± 4% ~ (p=0.086 n=29+28) Gzip-4 396ms ± 4% 400ms ± 4% +0.99% (p=0.026 n=30+30) Gunzip-4 41.1ms ± 3% 41.2ms ± 3% ~ (p=0.495 n=30+30) HTTPClientServer-4 63.7µs ± 3% 63.3µs ± 2% ~ (p=0.113 n=29+29) JSONEncode-4 16.1ms ± 2% 16.1ms ± 2% -0.30% (p=0.041 n=30+30) JSONDecode-4 60.9ms ± 3% 61.2ms ± 6% ~ (p=0.187 n=30+30) Mandelbrot200-4 5.17ms ± 2% 5.19ms ± 3% ~ (p=0.676 n=30+30) GoParse-4 3.28ms ± 3% 3.25ms ± 2% -0.97% (p=0.002 n=30+30) RegexpMatchEasy0_32-4 103ns ± 4% 104ns ± 4% ~ (p=0.352 n=30+30) RegexpMatchEasy0_1K-4 849ns ± 2% 845ns ± 2% ~ (p=0.381 n=30+30) RegexpMatchEasy1_32-4 113ns ± 4% 113ns ± 4% ~ (p=0.795 n=30+30) RegexpMatchEasy1_1K-4 1.03µs ± 3% 1.03µs ± 4% ~ (p=0.275 n=25+30) RegexpMatchMedium_32-4 132ns ± 3% 132ns ± 3% ~ (p=0.970 n=30+30) RegexpMatchMedium_1K-4 41.4µs ± 3% 41.4µs ± 3% ~ (p=0.212 n=30+30) RegexpMatchHard_32-4 2.22µs ± 4% 2.22µs ± 4% ~ (p=0.399 n=30+30) RegexpMatchHard_1K-4 67.2µs ± 3% 67.6µs ± 4% ~ (p=0.359 n=30+30) Revcomp-4 1.84s ± 2% 1.83s ± 2% ~ (p=0.532 n=30+30) Template-4 69.1ms ± 4% 68.8ms ± 3% ~ (p=0.146 n=30+30) TimeParse-4 441ns ± 3% 442ns ± 3% ~ (p=0.154 n=30+30) TimeFormat-4 413ns ± 3% 414ns ± 3% ~ (p=0.275 n=30+30) [Geo mean] 66.2µs 66.0µs -0.28% name old speed new speed delta GobDecode-4 105MB/s ± 5% 106MB/s ± 5% ~ (p=0.514 n=30+29) GobEncode-4 111MB/s ± 5% 113MB/s ± 4% +1.37% (p=0.046 n=28+28) Gzip-4 49.1MB/s ± 4% 48.6MB/s ± 4% -0.98% (p=0.028 n=30+30) Gunzip-4 472MB/s ± 4% 472MB/s ± 3% ~ (p=0.496 n=30+30) JSONEncode-4 120MB/s ± 2% 121MB/s ± 2% +0.29% (p=0.042 n=30+30) JSONDecode-4 31.9MB/s ± 3% 31.7MB/s ± 6% ~ (p=0.186 n=30+30) GoParse-4 17.6MB/s ± 3% 17.8MB/s ± 2% +0.98% (p=0.002 n=30+30) RegexpMatchEasy0_32-4 309MB/s ± 4% 307MB/s ± 4% ~ (p=0.501 n=30+30) RegexpMatchEasy0_1K-4 1.21GB/s ± 2% 1.21GB/s ± 2% ~ (p=0.301 n=30+30) RegexpMatchEasy1_32-4 283MB/s ± 4% 282MB/s ± 3% ~ (p=0.877 n=30+30) RegexpMatchEasy1_1K-4 1.00GB/s ± 3% 0.99GB/s ± 4% ~ (p=0.276 n=25+30) RegexpMatchMedium_32-4 7.54MB/s ± 3% 7.55MB/s ± 3% ~ (p=0.528 n=30+30) RegexpMatchMedium_1K-4 24.7MB/s ± 3% 24.7MB/s ± 3% ~ (p=0.203 n=30+30) RegexpMatchHard_32-4 14.4MB/s ± 4% 14.4MB/s ± 4% ~ (p=0.407 n=30+30) RegexpMatchHard_1K-4 15.3MB/s ± 3% 15.1MB/s ± 4% ~ (p=0.306 n=30+30) Revcomp-4 138MB/s ± 2% 139MB/s ± 2% ~ (p=0.520 n=30+30) Template-4 28.1MB/s ± 4% 28.2MB/s ± 3% ~ (p=0.149 n=30+30) [Geo mean] 81.5MB/s 81.5MB/s +0.06% Change-Id: I7f75425f79eec93cdd8fdd94db13ad4f61b6a2f5 Reviewed-on: https://go-review.googlesource.com/133657 Run-TryBot: Ben Shi <powerman1st@163.com> TryBot-Result: Gobot Gobot <gobot@golang.org> Reviewed-by: Keith Randall <khr@golang.org>		2018-09-07 01:20:45 +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.
