#12847: ghci -fobject-code -O2 doesn't do the same optimisations as ghc --make -O2 -------------------------------------+------------------------------------- Reporter: nh2 | Owner: (none) Type: bug | Status: closed Priority: normal | Milestone: Component: Compiler | Version: 8.0.1 Resolution: duplicate | Keywords: Operating System: Other | Architecture: Type of failure: Compile-time | Unknown/Multiple performance bug | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Changes (by RolandSenn): * status: new => closed * resolution: => duplicate Comment: This is the same bug as in #13002. During startup without a -O flag on the command line, GHCi misses to store optimization data (like inline pragmas and rewrite rules). After a :set -O2 this optimization data is missing. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/12847#comment:3 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
