Re: Profiling question

Ah, I'd definatly like to request it for GHC. as well as a version in the IO monad, I have wanted both on various occasions. John On Mon, Jan 06, 2003 at 12:55:35PM +0000, Malcolm Wallace wrote:

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?
