I didn't know about glasgow-haskell-users, thanks! The files and their modifications are below, I was hoping this was going to be just a quick experiment (copying someone else's primop) … the web references identify only the two files to add an inline primop ...

...

./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)

Hi Paul,

The ghc-users list might get you a quicker response to this sort of question.

Maybe a good start would be to give us a listing of which files you've modified so far.

Alright, I wandered through some primtype issues, but I'm having another odd problem as I try to define my own primop. 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.

./compiler/prelude/primops.txt.pp primop FloatVAddOp "plusFloatVec#" Dyadic Float# -> Float# -> Float# with commutable = True

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?????

Perhaps! I wasn't sure if it was too noisy to be noticed. On Oct 14, 2011 5:54 PM, "Erik de Castro Lopo" wrote:

Actually the ghc-cvs list may be even better.
