#12545: Compilation time/space regression in GHC 8.0/8.1 (search in type-level lists and -O) -------------------------------------+------------------------------------- Reporter: | Owner: (none) mikhail.vorozhtsov | Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 8.0.1 Resolution: | Keywords: Inlining Operating System: Unknown/Multiple | Architecture: Type of failure: Compile-time | Unknown/Multiple performance bug | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by simonpj): Incidentally, HEAD is much much better: {{{ 7.10 19.2G allocated by GHC 50 seconds HEAD 7.1G allocated by GHC 30 seconds }}} I gave up waiting for 8.0. So apparently the original problem has gone away, although I'd quite like to know how! -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/12545#comment:13 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
