Function cleanGoRoot

benchext/utils_for_test.go:11–24

cleanGoRoot is similar to tracetest, but deals with GOROOT paths. It replaces paths+line numbers for fixed values so we can use the output in an example test.

(s string)

// It replaces paths+line numbers for fixed values so we can use the
// output in an example test.

	gorootPath := regexp.MustCompile("/.*/src/")
	s = gorootPath.ReplaceAllString(s, "/goroot/src/")

	fileLine := regexp.MustCompile(`/goroot/.*:[0-9]+`)

		file, _, ok := strings.Cut(path, ":")
		if !ok {
			return path
