'reduction' has a few restrictions over normal 'var-list' clauses: 1- On parallel, a num_gangs can only have 1 argument when combined with reduction. These two aren't able to be combined on any other of the compute constructs however. 2- The vars all must be 'numerical data types' types of some sort, or a 'composite of numerical data types'. A list of types is given in the standard as a minimum, so we choose 'isScalar', which covers all of these types and keeps types that are actually numeric. Other compilers don't seem to implement the 'composite of numerical data types', though we do. 3- Because of the above restrictions, member-of-composite is not allowed, so any access via a memberexpr is disallowed. Array-element and sub-arrays (aka array sections) are both permitted, so long as they meet the requirements of #2. This patch implements all of these for compute constructs.
