#7952: Can cost-centre annotations be included in -ddump-simpl? ---------------------------------+------------------------------------------ Reporter: nr | Owner: Type: feature request | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.6.3 Keywords: Core | Os: Unknown/Multiple Architecture: Unknown/Multiple | Failure: None/Unknown Difficulty: Unknown | Testcase: Blockedby: | Blocking: Related: | ---------------------------------+------------------------------------------ Comment(by simonmar): Sadly the situation with Cost Centre Stacks is that it's still work in progress and I didn't manage to document it (beyond comments in the code) before I left MSR. Simon is right that you can't statically determine which CCS a particular allocation will be attributed to. However, if the `let` is within the scope of a particular SCC, then the allocation should be attributed to Cost Centre Stacks that have that SCC label on the top. There might be many such stacks in the profile, if the current function was called from multiple different places. -- Ticket URL: http://hackage.haskell.org/trac/ghc/ticket/7952#comment:2 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
