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
