#11542: Profiling call count frequently 0 when it shouldn't be -------------------------------------+------------------------------------- Reporter: augustss | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Profiling | Version: 7.8.3 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by nad): I don't know if this is related, but I've encountered an example where the entries count is 0, but the ''individual'' %time and %alloc numbers are substantial. This is using GHC 7.10.3. I found a report of a similar problem: Profiling trouble by Ferenc Wagner (https://mail.haskell.org/pipermail/glasgow-haskell- users/2003-January/004727.html). The code attached to the report compiles if you modify some haskell98 imports: {{{ sed -ri -e 's/import Complex/import Data.Complex/' -e 's/import qualified List/import qualified Data.List as List/' *hs ghc --make Show2.hs -O -auto-all -prof ./Show2 +RTS -p }}} When I ran this sequence of commands now I obtained a profiling report with the following line: {{{ main Main 109 0 10.5 0.8 10.5 0.8 }}} -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/11542#comment:3 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
