Comment(by igloo): Most of the regression comes from this patch: {{{ commit 980372f357667c1ba63b28acbf5798826890b7a5 Author: Simon Peyton Jones <simo...@microsoft.com> Date: Wed May 9 16:22:49 2012 +0100 Re-do the "function application discount" (fixes Trac #6048) }}} (the SimplCont patches also made things a bit worse, but I haven't looked into that at all). I think that the problem is more/bigger inlinings, rather than a space leak in GHC itself. I'll attach `CopyFile.hs`, and `before.txt` and `after.txt` showing the interface files before and after this patch is applied. -- Ticket URL: <http://hackage.haskell.org/trac/ghc/ticket/6104#comment:5> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler _______________________________________________ Glasgow-haskell-bugs mailing list Glasgow-haskell-bugs@haskell.org http://www.haskell.org/mailman/listinfo/glasgow-haskell-bugs
