#8299: Add richer data model address arithmetic: AddrDiff and AddrInt (ie d Int_ptr_diff and Int_ptr_size) ----------------------------+---------------------------------------------- Reporter: carter | Owner: Type: feature | Status: new request | Milestone: 7.10.1 Priority: high | Version: 7.6.3 Component: | Keywords: Compiler | Architecture: Unknown/Multiple Resolution: | Difficulty: Project (more than a week) Operating System: | Blocked By: Unknown/Multiple | Related Tickets: Type of failure: | None/Unknown | Test Case: | Blocking: 8287 | ----------------------------+---------------------------------------------- Comment (by carter): agreed with Reid. its worth remarking though, that internally that CPtrdiff type is just Int64 on x86_64. It really needs to be a distinguished type internally, not just a newtype wrapper around an Int (at least for a satisfactory analogue for GHC and correct code gen) -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8299#comment:2 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
