IMULL/DIVSS/DIVSD all can take the source operand from memory directly. And this CL implement that optimization. 1. The total size of pkg/linux_386 decreases about 84KB (excluding cmd/compile). 2. The go1 benchmark shows little regression in total (excluding noise). name old time/op new time/op delta BinaryTree17-4 3.29s ± 2% 3.27s ± 4% ~ (p=0.192 n=30+30) Fannkuch11-4 3.49s ± 2% 3.54s ± 1% +1.48% (p=0.000 n=30+30) FmtFprintfEmpty-4 45.9ns ± 3% 46.3ns ± 4% +0.89% (p=0.037 n=30+30) FmtFprintfString-4 78.8ns ± 3% 78.7ns ± 4% ~ (p=0.209 n=30+27) FmtFprintfInt-4 91.0ns ± 2% 90.3ns ± 2% -0.82% (p=0.031 n=30+27) FmtFprintfIntInt-4 142ns ± 4% 143ns ± 4% ~ (p=0.136 n=30+30) FmtFprintfPrefixedInt-4 181ns ± 3% 183ns ± 4% +1.40% (p=0.005 n=30+30) FmtFprintfFloat-4 404ns ± 4% 408ns ± 3% ~ (p=0.397 n=30+30) FmtManyArgs-4 601ns ± 3% 609ns ± 5% ~ (p=0.059 n=30+30) GobDecode-4 7.21ms ± 5% 7.24ms ± 5% ~ (p=0.612 n=30+30) GobEncode-4 6.91ms ± 6% 6.91ms ± 6% ~ (p=0.797 n=30+30) Gzip-4 398ms ± 6% 399ms ± 4% ~ (p=0.173 n=30+30) Gunzip-4 41.7ms ± 3% 41.8ms ± 3% ~ (p=0.423 n=30+30) HTTPClientServer-4 62.3µs ± 2% 62.7µs ± 3% ~ (p=0.085 n=29+30) JSONEncode-4 21.0ms ± 4% 20.7ms ± 5% -1.39% (p=0.014 n=30+30) JSONDecode-4 66.3ms ± 3% 67.4ms ± 1% +1.71% (p=0.003 n=30+24) Mandelbrot200-4 5.15ms ± 3% 5.16ms ± 3% ~ (p=0.697 n=30+30) GoParse-4 3.24ms ± 3% 3.27ms ± 4% +0.91% (p=0.032 n=30+30) RegexpMatchEasy0_32-4 101ns ± 5% 99ns ± 4% -1.82% (p=0.008 n=29+30) RegexpMatchEasy0_1K-4 848ns ± 4% 841ns ± 2% -0.77% (p=0.043 n=30+30) RegexpMatchEasy1_32-4 106ns ± 6% 106ns ± 3% ~ (p=0.939 n=29+30) RegexpMatchEasy1_1K-4 1.02µs ± 3% 1.03µs ± 4% ~ (p=0.297 n=28+30) RegexpMatchMedium_32-4 129ns ± 4% 127ns ± 4% ~ (p=0.073 n=30+30) RegexpMatchMedium_1K-4 43.9µs ± 3% 43.8µs ± 3% ~ (p=0.186 n=30+30) RegexpMatchHard_32-4 2.24µs ± 4% 2.22µs ± 4% ~ (p=0.332 n=30+29) RegexpMatchHard_1K-4 68.0µs ± 4% 67.5µs ± 3% ~ (p=0.290 n=30+30) Revcomp-4 1.85s ± 3% 1.85s ± 3% ~ (p=0.358 n=30+30) Template-4 69.6ms ± 3% 70.0ms ± 4% ~ (p=0.273 n=30+30) TimeParse-4 445ns ± 3% 441ns ± 3% ~ (p=0.494 n=30+30) TimeFormat-4 412ns ± 3% 412ns ± 6% ~ (p=0.841 n=30+30) [Geo mean] 66.7µs 66.8µs +0.13% name old speed new speed delta GobDecode-4 107MB/s ± 5% 106MB/s ± 5% ~ (p=0.615 n=30+30) GobEncode-4 111MB/s ± 6% 111MB/s ± 6% ~ (p=0.790 n=30+30) Gzip-4 48.8MB/s ± 6% 48.7MB/s ± 4% ~ (p=0.167 n=30+30) Gunzip-4 465MB/s ± 3% 465MB/s ± 3% ~ (p=0.420 n=30+30) JSONEncode-4 92.4MB/s ± 4% 93.7MB/s ± 5% +1.42% (p=0.015 n=30+30) JSONDecode-4 29.3MB/s ± 3% 28.8MB/s ± 1% -1.72% (p=0.003 n=30+24) GoParse-4 17.9MB/s ± 3% 17.7MB/s ± 4% -0.89% (p=0.037 n=30+30) RegexpMatchEasy0_32-4 317MB/s ± 8% 324MB/s ± 4% +2.14% (p=0.006 n=30+30) RegexpMatchEasy0_1K-4 1.21GB/s ± 4% 1.22GB/s ± 2% +0.77% (p=0.036 n=30+30) RegexpMatchEasy1_32-4 298MB/s ± 7% 299MB/s ± 4% ~ (p=0.511 n=30+30) RegexpMatchEasy1_1K-4 1.00GB/s ± 3% 1.00GB/s ± 4% ~ (p=0.304 n=28+30) RegexpMatchMedium_32-4 7.75MB/s ± 4% 7.82MB/s ± 4% ~ (p=0.089 n=30+30) RegexpMatchMedium_1K-4 23.3MB/s ± 3% 23.4MB/s ± 3% ~ (p=0.181 n=30+30) RegexpMatchHard_32-4 14.3MB/s ± 4% 14.4MB/s ± 4% ~ (p=0.320 n=30+29) RegexpMatchHard_1K-4 15.1MB/s ± 4% 15.2MB/s ± 3% ~ (p=0.273 n=30+30) Revcomp-4 137MB/s ± 3% 137MB/s ± 3% ~ (p=0.352 n=30+30) Template-4 27.9MB/s ± 3% 27.7MB/s ± 4% ~ (p=0.277 n=30+30) [Geo mean] 79.9MB/s 80.1MB/s +0.15% Change-Id: I97333cd8ddabb3c7c88ca5aa9e14a005b74d306d Reviewed-on: https://go-review.googlesource.com/120695 Run-TryBot: Ben Shi <powerman1st@163.com> 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.
