#5218: Add unpackCStringLen# to create Strings from string literals -------------------------------------+------------------------------------- Reporter: tibbe | Owner: thoughtpolice Type: feature request | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.0.3 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: Runtime | Unknown/Multiple performance bug | Test Case: Blocked By: | Blocking: Related Tickets: #5877 #10064 | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by jscholl): Wouldn't that generate something like {{{unpackCString# (# 3#, "abc"# #)}}} for {{{"abc"}}}? And if I just typed "abc" in ghci, wouldn't it fail as ghci can not handle unboxed tuples? Beside from that, it should work, but then I could also just try to change {{{unpackCString#}}} to have type {{{Addr# -> Int# -> [Char]}}}, avoiding the tuple. This would of course break backwards compatibility, as would an unboxed tuple, and I wanted to see if I could avoid that. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/5218#comment:43 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
