This change adds a flag to cmd/bench to do a few runs to collect profiles and feed that back into the build before doing measured benchmark runs. This mode is only supported in Sweet to begin with.

This subrepository holds macro-benchmarks used for Go performance development and monitoring. Each benchmark is compiled into a separate binary. To build and install them all in the current directory, execute: $ GOBIN=$PWD go get golang.org/x/benchmarks/... To run a benchmark, simply execute its binary. Each binary has a number of flags to control benchmark duration, etc. Run with '-help' to get the full list of flags. When the benchmarking finishes, the binary prints results in the standard Go benchmark format [1]: $ garbage BenchmarkGarbage/benchmem-MB=64-4 2000 6443223 ns/op 6008832 GC-bytes-from-system 230521 STW-ns/GC 15329 STW-ns/op 2780501 allocated-bytes/op 68636 allocs/op 119041368 bytes-from-system 104202240 heap-bytes-from-system 8109400 other-bytes-from-system 112427008 peak-RSS-bytes 121511936 peak-VM-bytes 720896 stack-bytes-from-system 25194000 user+sys-ns/op This format can be processed by tools like benchstat (https://golang.org/x/perf/cmd/benchstat) and benchplot (https://godoc.org/github.com/aclements/go-misc/benchplot). Required extra tools: For Linux, you need "perf". On Debian/Ubuntu, you can install package "perf-tools-common" to get it. Run "perf" once with no arguments to check if it requires additional packages to be installed. To submit changes to this repository, see http://golang.org/doc/contribute.html.
