I'm trying to enable some ticky counters for profiling the RTS code (eg in Storage.c:allocate). Much of the code was already in place, but disabled via CPP. I can enable the counters, but I'm having trouble making them only tick in the debug RTS. Can someone advise regarding the presence/accuracy of, say, the TICKY_TICKY symbol within the $(TOP)/includes/stg/Ticky.h file? Recap: * I use a macro in Storage.c to tick a ticky counter * The macro is #defined in stg/Ticky.h * I'd like the macro definition to be empty unless the Rts build way is DEBUG * There's this TICKY_TICKY symbol already floating around, so that seems like the right symbol to check * Thus: what do #include in stg/Ticky.h to make TICKY_TICKY accurate wrt to the build way? Maybe I'm dense at the moment, but trying some of the straight-forward options suggested by http://hackage.haskell.org/trac/ghc/wiki/Commentary/SourceTree/Includes didn't seem to help. Thanks.
