Paul Always switch on -dcore-lint; it's a self-checker for types, and usually nails an error much closer to the source.
Simon From: glasgow-haskell-users-boun...@haskell.org [mailto:glasgow-haskell-users-boun...@haskell.org] On Behalf Of Paul Monday Sent: 16 October 2011 16:54 To: glasgow-haskell-users@haskell.org Subject: Implementing a new Primop, stage1 panic (Reposting since this got cross-posted sort of oddly and I wasn't subscribed yet) I'm having an odd problem as I try to define my own primop, it seems that some docs may be out of date with respect to all of the touch points for a simple primop addition. I've followed what the various wiki pages have to offer (primarily http://hackage.haskell.org/trac/ghc/wiki/AddingNewPrimitiveOperations and http://hackage.haskell.org/trac/ghc/wiki/Commentary/PrimOps) without success. I even unraveled my PrimOp to be, basically, an exact copy of another PrimOp without luck. The primop I'm attempting to add is now very, very simple and copies FloatAddOp exactly so there must be an additional file I have to modify before the primop is "completely" added. Here are my simple modifications: ./compiler/prelude/primops.txt.pp primop FloatVAddOp "plusFloatVec#" Dyadic Float# -> Float# -> Float# with commutable = True ./compiler/codeGen/CgPrimOp.hs translateOp FloatVAddOp = Just (MO_F_Add W32) The compiler error is below. I have the feeling that an interface is not being built somewhere ... this must be a simple one but I can't find any references to this error anywhere ... has anyone seen this one before?????
