#5925: Add inline version of newArray# -------------------------------------+------------------------------------ Reporter: tibbe | Owner: Type: feature request | Status: new Priority: normal | Milestone: 7.6.2 Component: Compiler | Version: 7.4.1 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Unknown/Multiple Type of failure: None/Unknown | Difficulty: Unknown Test Case: | Blocked By: 4258 Blocking: | Related Tickets: -------------------------------------+------------------------------------ Comment (by tibbe): I have something that works. I will post a patch later tonight. Benchmark: allocating 100,000,000 `MutableArray# ()` of size 16 in a loop. Best out of three runs for old implementation: {{{ $ time ./NewArraySlow real 0m2.741s user 0m2.696s sys 0m0.043s }}} Best out of three runs for new implementation: {{{ $ time ./NewArrayNew real 0m1.490s user 0m1.449s sys 0m0.041s }}} That's almost 2x faster. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/5925#comment:15 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
