#9476: Implement late lambda-lifting -------------------------------------+------------------------------------- Reporter: simonpj | Owner: sgraf Type: feature request | Status: closed Priority: normal | Milestone: 8.8.1 Component: Compiler | Version: 7.8.2 Resolution: fixed | Keywords: LateLamLift Operating System: Unknown/Multiple | Architecture: Type of failure: Runtime | Unknown/Multiple performance bug | Test Case: Blocked By: | Blocking: Related Tickets: #8763 #13286 | Differential Rev(s): Phab:D5224 Wiki Page: LateLamLift | -------------------------------------+------------------------------------- Comment (by sgraf): Ah, just remembered that counted instructions were the original reason to look into this and with the NCG, cachegrind reports less instructions for `./allow-cg 17 +RTS -s -A128M -H1G` than for `./default 17 +RTS -s -A128M -H1G`. Compiling with `-fllvm -optlo -Os` works around this, so I'll try a benchmark run with that. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9476#comment:66 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
