#10401: state hack-related regression -------------------------------------+------------------------------------- Reporter: rwbarton | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.10.1 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: Runtime | Unknown/Multiple performance bug | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Revisions: -------------------------------------+------------------------------------- Comment (by rwbarton): But the ticket is mostly about the behavior of 7.10.1 with `-O2 -fno- state-hack`. Does that change things? (Probably should have been clearer about this.) In 7.8 we have `-fno-state-hack` as an escape hatch for when the state hack heuristic goes wrong. But we can't expect people to rebuild all their dependencies including `base` with `-fno-state-hack`, and disabling optimizations completely is not very satisfactory either. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10401#comment:2 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
