#9291: Don't reconstruct sum types if the type subtly changes -------------------------------------+------------------------------------- Reporter: schyler | Owner: nomeata Type: feature request | Status: closed Priority: normal | Milestone: Component: Compiler | Version: 7.8.2 Resolution: fixed | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: Runtime | Unknown/Multiple performance bug | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Phab:D2871 Wiki Page: | -------------------------------------+------------------------------------- Comment (by nomeata):
Will you revisit the -O2 inclusion sometime later? /me was always under the impression that all performance-increasing optimisations from -O would be included in -O2.
Oh, of course it is in `-O2`! The question is whether it should only be in `-O`. -- Ticket URL: <http://ghc.haskell.org/trac/ghc/ticket/9291#comment:45> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler
