#14998: Sort out the strictness mess for exceptions -------------------------------------+------------------------------------- Reporter: simonpj | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: 8.4.3 Component: Compiler | Version: 8.2.2 Resolution: | Keywords: Exceptions 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 sgraf): Re: item 4. Isn't [https://hackage.haskell.org/package/ghc-8.4.1/docs/CoreUtils.html#v:exprOkFo... exprOkForSpeculation or exprOkForSideEffects] exactly what we want, rather than just `isPrimOpId`? I don't think the limited convergence checking that nested CPR would bring (it should not allow arbitrary costly converging expression anyway) has any benefit over those functions. I could give those a try, if you want. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14998#comment:21 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
