#8903: Add dead store elimination -------------------------------------+------------------------------------- Reporter: tibbe | Owner: (none) Type: feature request | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.9 Resolution: | Keywords: CodeGen Operating System: Unknown/Multiple | Architecture: Type of failure: Runtime | Unknown/Multiple performance bug | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by srb): Im willing to take this on, although I still haven't fully wrapped my head around Hoopl. If it's OK for me to have a go, I would appreciate it if I could have some advice on a few issues: 1) This proposed analysis seems quite similar to what's being done in CmmLive/CmmSink. Would it be a good idea to attempt to incorporate it into those passes? 2) The liveness analysis is also used for inlining assignments which are used once, propagating constants, and pushing down assigments. Is it a good idea to do the same thing with stores? Thanks, Sean -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8903#comment:4 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
