Dear GHC experts,
I have another question about the profiling usage in ghc-6.2.2.
I thank "Simon Marlow"
There was set a single point of {-# SCC "isReducibleAtTop" #-}. Why the report prints the two different lines for it?
You removed the indentation, which was there to indicate the call nesting. A cost centre that appears more than once indicates that it was called in two places in your program (or called with two different lexical call stacks, to be precise).
The indentation in the profiling report or in the source program? The report prints some function names not from the beginning of the line ... Maybe, you can give a simple example of a program with SCC when the center is printed twice? For I do not understand this point. Now I replaced SCC with -auto-all, and it gives a report which looks satisfactory. The first part lpo TermComp 29.9 47.0 relates Prelude1 13.1 1.5 ... is helpful all right. But I also need to know how many times there was called a certain function f, no matter from where it is called and whether it occurs in the first part of the report. I search for `f' in the large second part of the report. And find the two (often many) lines (with different indentation): f Module1 10 20 ... ... f Module1 121 30 ... So, `f' was entered 20 times from one point and 30 times from another, and 50 times in total. Right? Thank you in advance for the explanation. ----------------- Serge Mechveliani mechvel@botik.ru
