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>

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>
