Abstract
Reducing coherency problems in a data processing system is provided. Source code that is to be compiled is received and analyzed to identify at least one of a plurality of loops that contain a memory reference. A determination is made as to whether the memory reference is an access to a global memory that should be handled by a direct buffer. Responsive to an indication that the memory reference is an access to the global memory that should be handled by the direct buffer, the memory reference is marked for direct buffer transformation. The direct buffer transformation is then applied to the memory reference.
