#10491: Regression, simplifier explosion with Accelerate, cannot compile, increasing tick factor is not a workaround -------------------------------------+------------------------------------- Reporter: robertce | Owner: Type: bug | Status: new Priority: highest | Milestone: 7.10.2 Component: Compiler | Version: 7.10.1 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: Compile-time | Unknown/Multiple performance bug | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Revisions: -------------------------------------+------------------------------------- Comment (by George): I think something needs to be changed. AFAIK, there is no documentation that it is order dependent. A language that is not order dependent should not have command line options that are! As a minimum if -O2 and -fno<something> means -f<something> and -fno<something> and some remaining -f<options> then the user should get an error message if the order is "wrong" and no error message if the order is right, i.e. -fno<something> wins. At least, this is what I think off the top of my head from my naive viewpoint. I believe there is a ticket for an ER or task to improve command line options. I'll try to find it. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10491#comment:31 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
