#8199: Get rid of HEAP_ALLOCED ----------------------------+---------------------------------------------- Reporter: ezyang | Owner: ezyang Type: feature | Status: new request | Milestone: 7.10.1 Priority: normal | Version: 7.7 Component: | Keywords: Compiler | Architecture: Unknown/Multiple Resolution: | Difficulty: Project (more than a week) Operating System: | Blocked By: 5435 Unknown/Multiple | Related Tickets: Type of failure: | None/Unknown | Test Case: | Blocking: | ----------------------------+---------------------------------------------- Comment (by simonmar): FYI, I think you uploaded the wrong patch for the latest patch (version 4). Points 1 and 2 are unavoidable. Point 3 is interesting - I think we could probably do better there, but we should look at the context a bit more. In many cases where we have a tagged pointer, we take the tag into account when operating on it (e.g. field index), but here it looks like we're just unconditionally zeroing the tag bits. Point 4 might be improved by overlapping the indirection word with the closure itself. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8199#comment:19 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
