If you want to count how many times a function is entered, why not just
#10613: Mechanism for checking that we only enter single-entry thunks once -------------------------------------+------------------------------------- Reporter: bgamari | Owner: Type: feature request | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.10.1 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: Other | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by nomeata): put a ticky counter at the start of the function's code? The problem is that I need to count each dynamic instance separately. So I need a separate counter for each allocated closure, so the only place it can go is inside the closer as another non-pointer argument. (For static functions, things are easier of course.) -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10613#comment:17 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
