Meta-bug to track (still) missed optimizations in tramp3d-v4 testcase
and so in FreePOOMA library using code.
Full tramp3d-v4 can be fetched from
http://www.tat.physik.uni-tuebingen.de/~rguenth/gcc/tramp3d-v4.cpp.gz
attached is a reduced testcase (compile-time only), which instantiates
one of the expression kernels representative for the application. Look
at
;; Function void MultiArgKernel<MultiArg, Function>::run() [with MultiArg = Mult
iArg2<Field<UniformRectilinearMesh<MeshTraits<3, double, UniformRectilinearTag,
CartesianTag, 3> >, double, BrickViewU>, Field<UniformRectilinearMesh<MeshTraits

preferably compile with "-O2 -Dleafify=flatten".
