sum-instrinsic to code transformation #1711

Closed rupertford closed 1 year ago

rupertford commented 2 years ago

OpenACC kernel regions do not work well with the sum intrinsic when it has a 'dimension' named argument. Changing this intrinsic to equivalent code improves the performance of NEMO in manual tests. Now that named arguments are supporting in the PSyIR we can create a new sum2code transformation that allows us to do this in PSyclone.
