#12849: hsc2hs trouble with floating-point constants in cross-compilation mode -------------------------------------+------------------------------------- Reporter: rwbarton | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: hsc2hs | Version: 7.8.4 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by rwbarton): A separate issue about hsc2hs and floating-point types: the argument to `#const` gets cast to `long` in direct mode. The hsc2hs manual alludes to this, but does not state it explicitly. So for example, `#const (-1.9)` produces the output `-1`. We should state this explicitly in the manual, and also insert a cast to `long` in the cross-compilation code path to ensure that it matches the direct code path output. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/12849#comment:2 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
