#13360: Add a flag to enable inferring HasCallStack constraints -------------------------------------+------------------------------------- Reporter: gridaphobe | Owner: (none) Type: feature request | Status: new Priority: normal | Milestone: 8.4.1 Component: Compiler | Version: 8.0.1 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 saurabhnanda):
My suspicion is that this will show that performance regresses by approximately the same amount as -fprof-auto -prof since operationally the two approaches are somewhat similar.
Where can I read more about what `-fprof-auto -prof` does?
However, this does raise a question: What prevents you from just using cost center stacks?
By cost-center stacks, do you mean whatever `-prof` does? Upon an exception, does it give a proper callstack? -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13360#comment:33 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
