#701: Better CSE optimisation -------------------------------------+-------------------------------------- Reporter: simonmar | Owner: michalt Type: task | Status: new Priority: normal | Milestone: _|_ Component: Compiler | Version: 6.4.1 Keywords: | Os: Unknown/Multiple Architecture: Unknown/Multiple | Failure: None/Unknown Difficulty: Difficult (2-5 days) | Testcase: N/A Blockedby: | Blocking: Related: | -------------------------------------+-------------------------------------- Comment(by simonmar): Looking at the tickets, they don't completely overlap. This one is about spotting common subexpressions when they don't occur in the form `let x = e in E[e]`. #2940 would fix some of those cases, but not all. -- Ticket URL: http://hackage.haskell.org/trac/ghc/ticket/701#comment:14 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
