#10397: Compiler performance regression 7.6 -> 7.8 in elimCommonBlocks -------------------------------------+------------------------------------- Reporter: TobyGoodwin | Owner: Type: bug | Status: merge Priority: normal | Milestone: 7.10.2 Component: Compiler | Version: 7.8.4 Resolution: fixed | Keywords: Operating System: Unknown/Multiple | performance Type of failure: None/Unknown | Architecture: Blocked By: | Unknown/Multiple Related Tickets: | Test Case: see ticket | Blocking: | Differential Revisions: Phab:D892 | Phab:D896 -------------------------------------+------------------------------------- Comment (by thoughtpolice): Joachim, I also picked this last one over to `ghc-7.10`, so these will all hit 7.10.2. @TobyGoodwin - Unfortunately, we aren't going to be doing any more releases of the 7.8.x series at this point, since the branch is quite out of date. In theory, all of the current performance fixes Joachim has made ''should'' apply to the 7.8 branch still, although there will probably be things like conflicts with whitespace and the tabs->spaces conversion that happened. I'm not sure what the policy is for upstream distributions here is, especially if they still aren't even shipping 7.8 to users - and if they aren't, can they not use 7.10? I have no clue what timeline most distros use for upgrading major versions of things like GHC. Luckily, for Debian, Joachim is the maintainer, so I'm sure he'll know the deal. :) -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10397#comment:33 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
