Martin Möhrmann b7a2d413a3 testing: print cpu type as label for benchmarks ... Supports 386 and amd64 architectures on all operating systems. Example output: $ go test -bench=.* goos: darwin goarch: amd64 pkg: strconv cpu: Intel(R) Core(TM) i7-3520M CPU @ 2.90GHz BenchmarkAtof64Decimal-4 24431032 46.8 ns/op ... As the displayed CPU information is only used for information purposes it is lazily initialized when needed using the new internal/sysinfo package. This allows internal/cpu to stay without dependencies and avoid initialization costs when the CPU information is not needed as the new code to query the CPU name in internal/cpu can be dead code eliminated if not used.
