#13518: CMM compiles with 8.0.2, fails with git HEAD -------------------------------------+------------------------------------- Reporter: erikd | Owner: (none) Type: bug | Status: closed Priority: normal | Milestone: 8.4.1 Component: Compiler | Version: 8.1 Resolution: invalid | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: Incorrect | Unknown/Multiple error/warning at compile-time | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by erikd):
I don't understand this comment: the Haskell stack is only word-aligned and the argument to reserve is in words, so it cannot unalign the stack.
On 32 but systems, `Double` is two words and on 64 bit systems, `Float` is half a word. I did have some CPP which tried to account for this and that is what was breaking when I first tries @slyfox's `TO_W_` technique.
I believe I32 w in the formal argument list is meaningless
So how does one express a `Word32` in a portable way in CMM? -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13518#comment:12 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
