Method findOrAdd

internal/report/report.go:367–383

findOrAdd takes a node representing a function, adds the function represented by the node to the map if the function is not already present, and returns the function the node represents. This also returns a boolean, which is true if the function was added and false otherwise.

// and returns the function the node represents. This also returns a boolean,
