With Simon's help I figured it out. I'm now refactoring StgCmmPrimOp so it's easier to have primops that have both inline and out-of-line implementations in the future. On Fri, Mar 7, 2014 at 3:19 PM, Carter Schonwald <carter.schonwald@gmail.com

Have you looked at some of the lowering code for other primops? What info are you missing?

Hi,
I'm trying to make allocation of arrays of small, statically-known size inline. For large or unknown size I just want to call the existing stg_newArrayzh function. In code:
doNewArrayOp :: DynFlags -> CmmFormal -> CmmExpr -> FCode () doNewArrayOp dflags res_r (CmmLit (CmmInt n _)) | n <= inlineAllocLimit = do -- Do everything inline. doNewArrayOp dflags res_r n = do emitCallTo "stg_newArrayzh" res_r n -- HERE
The question is: how do I emit a call to stg_newArrayzh, which is defined in PrimOps.cmm?
