As promised in CL 188238, removing the obsolete symbol. Here are the latest stats. This is baselined at "e53edafb" with only these changes applied, run on magna.cam. The linker looks straight better (in memory and speed). There is still a change I'm working on walking the progs to generate the debug_lines data in the compiler. That will likely result in a compiler speedup. name old time/op new time/op delta Template 324ms ± 3% 317ms ± 3% -2.07% (p=0.043 n=10+10) Unicode 142ms ± 4% 144ms ± 3% ~ (p=0.393 n=10+10) GoTypes 1.05s ± 2% 1.07s ± 2% +1.59% (p=0.019 n=9+9) Compiler 4.09s ± 2% 4.11s ± 1% ~ (p=0.218 n=10+10) SSA 12.5s ± 1% 12.7s ± 1% +1.00% (p=0.035 n=10+10) Flate 199ms ± 7% 203ms ± 5% ~ (p=0.481 n=10+10) GoParser 245ms ± 3% 246ms ± 5% ~ (p=0.780 n=9+10) Reflect 672ms ± 4% 688ms ± 3% +2.42% (p=0.015 n=10+10) Tar 280ms ± 4% 284ms ± 4% ~ (p=0.123 n=10+10) XML 379ms ± 4% 381ms ± 2% ~ (p=0.529 n=10+10) LinkCompiler 1.16s ± 4% 1.12s ± 2% -3.03% (p=0.001 n=10+9) ExternalLinkCompiler 2.28s ± 3% 2.23s ± 3% -2.51% (p=0.011 n=8+9) LinkWithoutDebugCompiler 686ms ± 9% 667ms ± 2% ~ (p=0.277 n=9+8) StdCmd 14.1s ± 1% 14.0s ± 1% ~ (p=0.739 n=10+10) name old user-time/op new user-time/op delta Template 604ms ±23% 564ms ± 7% ~ (p=0.661 n=10+9) Unicode 429ms ±40% 418ms ±37% ~ (p=0.579 n=10+10) GoTypes 2.43s ±12% 2.51s ± 7% ~ (p=0.393 n=10+10) Compiler 9.22s ± 3% 9.27s ± 3% ~ (p=0.720 n=9+10) SSA 26.3s ± 3% 26.6s ± 2% ~ (p=0.579 n=10+10) Flate 328ms ±19% 333ms ±12% ~ (p=0.842 n=10+9) GoParser 387ms ± 5% 378ms ± 9% ~ (p=0.356 n=9+10) Reflect 1.36s ±20% 1.43s ±21% ~ (p=0.631 n=10+10) Tar 469ms ±12% 471ms ±21% ~ (p=0.497 n=9+10) XML 685ms ±18% 698ms ±19% ~ (p=0.739 n=10+10) LinkCompiler 1.86s ±10% 1.87s ±11% ~ (p=0.968 n=10+9) ExternalLinkCompiler 3.20s ±13% 3.01s ± 8% -5.70% (p=0.046 n=8+9) LinkWithoutDebugCompiler 1.08s ±15% 1.09s ±20% ~ (p=0.579 n=10+10) name old alloc/op new alloc/op delta Template 36.3MB ± 0% 36.4MB ± 0% +0.26% (p=0.000 n=10+10) Unicode 28.5MB ± 0% 28.5MB ± 0% ~ (p=0.165 n=10+10) GoTypes 120MB ± 0% 121MB ± 0% +0.29% (p=0.000 n=9+10) Compiler 546MB ± 0% 548MB ± 0% +0.32% (p=0.000 n=10+10) SSA 1.84GB ± 0% 1.85GB ± 0% +0.49% (p=0.000 n=10+10) Flate 22.9MB ± 0% 23.0MB ± 0% +0.25% (p=0.000 n=10+10) GoParser 27.8MB ± 0% 27.9MB ± 0% +0.25% (p=0.000 n=10+8) Reflect 77.5MB ± 0% 77.7MB ± 0% +0.27% (p=0.000 n=9+9) Tar 34.5MB ± 0% 34.6MB ± 0% +0.23% (p=0.000 n=10+10) XML 44.2MB ± 0% 44.4MB ± 0% +0.32% (p=0.000 n=10+10) LinkCompiler 239MB ± 0% 230MB ± 0% -3.86% (p=0.000 n=10+10) ExternalLinkCompiler 243MB ± 0% 243MB ± 0% +0.22% (p=0.000 n=10+10) LinkWithoutDebugCompiler 164MB ± 0% 155MB ± 0% -5.45% (p=0.000 n=10+10) name old allocs/op new allocs/op delta Template 371k ± 0% 372k ± 0% +0.44% (p=0.000 n=10+10) Unicode 340k ± 0% 340k ± 0% +0.05% (p=0.000 n=10+10) GoTypes 1.32M ± 0% 1.32M ± 0% +0.46% (p=0.000 n=10+10) Compiler 5.34M ± 0% 5.37M ± 0% +0.59% (p=0.000 n=10+10) SSA 17.6M ± 0% 17.7M ± 0% +0.63% (p=0.000 n=10+10) Flate 233k ± 0% 234k ± 0% +0.48% (p=0.000 n=10+10) GoParser 309k ± 0% 310k ± 0% +0.40% (p=0.000 n=10+10) Reflect 964k ± 0% 969k ± 0% +0.54% (p=0.000 n=10+10) Tar 346k ± 0% 348k ± 0% +0.48% (p=0.000 n=10+9) XML 424k ± 0% 426k ± 0% +0.51% (p=0.000 n=10+10) LinkCompiler 751k ± 0% 645k ± 0% -14.13% (p=0.000 n=10+10) ExternalLinkCompiler 1.79M ± 0% 1.69M ± 0% -5.30% (p=0.000 n=10+10) LinkWithoutDebugCompiler 217k ± 0% 222k ± 0% +2.02% (p=0.000 n=10+10) name old object-bytes new object-bytes delta Template 547kB ± 0% 559kB ± 0% +2.17% (p=0.000 n=10+10) Unicode 215kB ± 0% 216kB ± 0% +0.60% (p=0.000 n=10+10) GoTypes 1.99MB ± 0% 2.03MB ± 0% +2.02% (p=0.000 n=10+10) Compiler 7.86MB ± 0% 8.07MB ± 0% +2.73% (p=0.000 n=10+10) SSA 26.4MB ± 0% 27.2MB ± 0% +3.27% (p=0.000 n=10+10) Flate 337kB ± 0% 343kB ± 0% +2.02% (p=0.000 n=10+10) GoParser 432kB ± 0% 441kB ± 0% +2.11% (p=0.000 n=10+10) Reflect 1.33MB ± 0% 1.36MB ± 0% +1.87% (p=0.000 n=10+10) Tar 477kB ± 0% 487kB ± 0% +2.24% (p=0.000 n=10+10) XML 617kB ± 0% 632kB ± 0% +2.33% (p=0.000 n=10+10) name old export-bytes new export-bytes delta Template 18.5kB ± 0% 18.5kB ± 0% ~ (all equal) Unicode 7.92kB ± 0% 7.92kB ± 0% ~ (all equal) GoTypes 35.0kB ± 0% 35.0kB ± 0% ~ (all equal) Compiler 109kB ± 0% 109kB ± 0% +0.09% (p=0.000 n=10+10) SSA 137kB ± 0% 137kB ± 0% +0.03% (p=0.000 n=10+10) Flate 4.89kB ± 0% 4.89kB ± 0% ~ (all equal) GoParser 8.49kB ± 0% 8.49kB ± 0% ~ (all equal) Reflect 11.4kB ± 0% 11.4kB ± 0% ~ (all equal) Tar 10.5kB ± 0% 10.5kB ± 0% ~ (all equal) XML 16.7kB ± 0% 16.7kB ± 0% ~ (all equal) name old text-bytes new text-bytes delta HelloSize 760kB ± 0% 760kB ± 0% ~ (all equal) CmdGoSize 10.8MB ± 0% 10.8MB ± 0% ~ (all equal) name old data-bytes new data-bytes delta HelloSize 10.7kB ± 0% 10.7kB ± 0% ~ (all equal) CmdGoSize 312kB ± 0% 312kB ± 0% ~ (all equal) name old bss-bytes new bss-bytes delta HelloSize 122kB ± 0% 122kB ± 0% ~ (all equal) CmdGoSize 146kB ± 0% 146kB ± 0% ~ (all equal) name old exe-bytes new exe-bytes delta HelloSize 1.11MB ± 0% 1.13MB ± 0% +1.10% (p=0.000 n=10+10) CmdGoSize 14.9MB ± 0% 15.0MB ± 0% +0.77% (p=0.000 n=10+10) Change-Id: I42e6087cd6231dbdcfff5464e46d373474e455e1 Reviewed-on: https://go-review.googlesource.com/c/go/+/192417Reviewed-by:
