#1257: Bytecode generator can't handle unboxed tuples -------------------------------------+------------------------------------- Reporter: igloo | Owner: Type: bug | Status: closed Priority: high | Milestone: 7.4.1 Component: GHCi | Version: 6.6 Resolution: wontfix | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: dsrun014 Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by dobenour): I can think of a few options - Auto-generate a bunch of return frames for different length tuples. Doesn't work because unboxed tuples can store unboxed data, so we get an exponential code size blowup. - Write a little interpreter (directly in Cmm) that looks at metadata in stack frame and does the appropriate operations. This one should work. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/1257#comment:12 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
