Timings is a simple data structure that collects times of labeled Start/Stop events describing timed phases, which later can be written to a file. Adjacent phases with common label prefix are automatically collected in a group together with the accumulated phase time. Timing data can be appended to a file in benchmark data format using the new -bench flag: $ go build -gcflags="-bench=/dev/stdout" -o /dev/null go/types commit: devel +8847c6b Mon Aug 15 17:51:53 2016 -0700 goos: darwin goarch: amd64 BenchmarkCompile:go/types:fe:init 1 663292 ns/op 0.07 % BenchmarkCompile:go/types:fe:loadsys 1 1337371 ns/op 0.14 % BenchmarkCompile:go/types:fe:parse 1 47008869 ns/op 4.91 % 10824 lines 230254 lines/s BenchmarkCompile:go/types:fe:typecheck:top1 1 2843343 ns/op 0.30 % BenchmarkCompile:go/types:fe:typecheck:top2 1 447457 ns/op 0.05 % BenchmarkCompile:go/types:fe:typecheck:func 1 15119595 ns/op 1.58 % 427 funcs 28241 funcs/s BenchmarkCompile:go/types:fe:capturevars 1 56314 ns/op 0.01 % BenchmarkCompile:go/types:fe:inlining 1 9805767 ns/op 1.02 % BenchmarkCompile:go/types:fe:escapes 1 53598646 ns/op 5.60 % BenchmarkCompile:go/types:fe:xclosures 1 199302 ns/op 0.02 % BenchmarkCompile:go/types:fe:subtotal 1 131079956 ns/op 13.70 % BenchmarkCompile:go/types:be:compilefuncs 1 692009428 ns/op 72.33 % 427 funcs 617 funcs/s BenchmarkCompile:go/types:be:externaldcls 1 54591 ns/op 0.01 % BenchmarkCompile:go/types:be:dumpobj 1 133478173 ns/op 13.95 % BenchmarkCompile:go/types:be:subtotal 1 825542192 ns/op 86.29 % BenchmarkCompile:go/types:unaccounted 1 106101 ns/op 0.01 % BenchmarkCompile:go/types:total 1 956728249 ns/op 100.00 % For #16169.
