Hi,
I am profiling a Haskell program using GHC, and after executing the
program with +RTS -p, I get a .prof file that lists the cost centers
of the program. Some of the cost centers listed are for function
symbols that do not exist in the given module. For example, I have in
my .prof file:
COST CENTRE MODULE %time %alloc
==_a2MT Foo 19.8 0.0
==_a2R8 Foo 17.8 0.0
==_a2Bg Bar 13.7 0.0
.... ....
It appears these are generated symbols; how do I find out what those
function symbols correspond to? (In this case, my assumption is that
these symbols refer to instances of the Eq class, but I'm not sure.)
[I couldn't find anything about this in the GHC online documentation
or via Googling, but sorry if I missed it.]
Thanks,
Lee
