I'd like to be able to determine the percentage of allocated objects of a particular type at specific points in a program's execution. I know that I can use heap profiling to create a graph of memory usage broken down by type, but is there any way to record this information at particular points in the program (i.e., between two statements in a do-expression)?
If you were using nhc98, then you could use the following: import NonStdProfile f ... = do ... profile "point A" actionA profile "point B" actionB The non-standard operation profile :: String -> a -> a places a labelled marker line on the profile graph at the time instant when the value is demanded. I don't know whether ghc has anything similar? Regards, Malcolm
