Following on from the work to implement MLIR -> LLVM IR Translation for Taskloop, this adds support for the following clauses to be used alongside taskloop: - if - grainsize - num_tasks - untied - Nogroup - Final - Mergeable - Priority These clauses are ones which work directly through the relevant OpenMP Runtime functions, so their information just needed collecting from the relevant location and passing through to the appropriate runtime function. Remaining clauses retain their TODO message as they have not yet been implemented.
