Constructors

FusedKer

Fields

• fsoac :: SOAC

  the SOAC expression, e.g., mapT( f(a,b), x, y )

• inplace :: Names

  Variables used in in-place updates in the kernel itself, as well as on the path to the kernel from the current position. This is used to avoid fusion that would violate in-place restrictions.

• fusedVars :: [VName]

  whether at least a fusion has been performed.

• fusedConsumed :: Names

  The set of variables that were consumed by the SOACs contributing to this kernel. Note that, by the type rules, the final SOAC may actually consume _more_ than its original contributors, which implies the need for Copy expressions.

• kernelScope :: Scope SOACS

  The names in scope at the kernel.

• outputTransform :: ArrayTransforms
• outNames :: [VName]
• kerAux :: StmAux ()
