#5364: Access RTS flag values from inside Haskell programs -------------------------------------+------------------------------------- Reporter: ezyang | Owner: ekmett Type: feature | Status: new request | Milestone: 7.10.1 Priority: normal | Version: 7.3 Component: Core | Keywords: Libraries | Architecture: Unknown/Multiple Resolution: | Difficulty: Unknown Operating System: | Blocked By: Unknown/Multiple | Related Tickets: Type of failure: | None/Unknown | Test Case: | Blocking: | Differential Revisions: Phab:D306 | -------------------------------------+------------------------------------- Changes (by hvr): * milestone: 7.12.1 => 7.10.1 Comment: btw, I noticed that the API exposed by GHC.RTS.Flags varies depending on `unsigned int`: {{{#!hs -- | @'nat'@ defined in @rts/Types.h@ type Nat = #{type unsigned int} data GCFlags = GCFlags { statsFile :: Maybe FilePath , giveStats :: GiveGCStats , maxStkSize :: Nat , initialStkSize :: Nat , stkChunkSize :: Nat ... }}} Is this really a good idea rather simply using `Word` which I assume should always be large enough to contain the range of `CULong`? Moreover, shouldn't most of those small-fields be `!`-ed to avoid thunks and unecessary pointer chasing? -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/5364#comment:11 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
