[GHC] #13864: RTS Stats are recorded without -T
#13864: RTS Stats are recorded without -T -------------------------------------+------------------------------------- Reporter: glguy | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: Component: Runtime | Version: 8.2.1-rc2 System | Keywords: | Operating System: Unknown/Multiple Architecture: | Type of failure: None/Unknown Unknown/Multiple | Test Case: | Blocked By: Blocking: | Related Tickets: Differential Rev(s): | Wiki Page: -------------------------------------+------------------------------------- The GHC.Stats module documents that I need to run my program with -T to generate stats, but I don't seem to need to. Perhaps the documentation is wrong or the stats are being collected when they shouldn't be. This is a regression(?) from GHC 8.0.2 where -T was required. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13864 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler

Indeed 12ad4d417b89462ba8e19a3c7772a931b3a93f0e (Throw an exception on heap overflow) changed `initRtsFlagsDefaults` to enable stats collection by default. It's not entirely clear why, but I suspect it was a mistake. DemiMarie, do you have any recollection of this? -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13864#comment:1 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler

However, I'm not sure I agree with how we went about this. If stat collection is now really mandatory then either we should remove the ability to disable it or just make sure that we always collect the bits that we need. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13864#comment:2 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
