subsequent non-comment line. Inline comments are also supported; the regexp will be matched against the code found on the same line: func Sqrt(x float64) float64 { return math.Sqrt(x) // arm:"SQRTD" } It's possible to specify a comma-separated list of regexps to be matched. For example, the following test: func TZ8(n uint8) int { // amd64:"BSFQ","ORQ\t\\$256"
