The present invention extends to methods, systems, and computer program products for aliasing buffers. Embodiment of the inventions supporting buffer aliasing through introduction of a level of indirection between a source program's buffer accesses and the target executable physical buffers, and binding the logical buffer accesses to actual physical buffer accesses at runtime. A variety of techniques for can be used supporting runtime aliasing of buffers, in a system which otherwise disallows such runtime aliasing between separately defined buffers in the target executable code. Binding of logical buffer accesses in the source program to the actual physical buffers defined in the target executable code is delayed until runtime.
