#9279: Local wrapper function remains in final program; result = extra closure allocation -------------------------------------+------------------------------------- Reporter: simonmar | Owner: simonpj Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.8.2 Resolution: | Keywords: Operating System: | Architecture: Unknown/Multiple Unknown/Multiple | Difficulty: Unknown Type of failure: Runtime | Blocked By: performance bug | Related Tickets: Test Case: | Blocking: | Differential Revisions: | -------------------------------------+------------------------------------- Comment (by nfrisby): 9c2904c, the tip of `wip/llf`, using my recommended settings (cf LateLamLift) does lift our `$wa4` (or whatever lead to it). The new attachment is the output of `/home/nifr/tmp/llf-for-9279/bin/ghc -fforce-recomp -O2 $(echo $(cat ~/ghc-llf/llf-nr10-r6)) -c Haxl/Core/Monad.hs -ddump-llf -ddump-simpl -dsuppress-all`. The subcommand spews out the "recommended settings" that I refer to as llf-nr10-r6.
