One embodiment provides for a computer-implemented method comprising receiving a request to compile a set of program instructions coded in a high-level language, the set of program instructions including a pointer to a virtual memory address, the pointer having a pointer encoding including a base address and a length; while compiling the set of program instructions, decoding the base address and length from the pointer, wherein the base address specifies a first boundary for a memory allocation, the length defines a second boundary for the memory allocation and the length is an encoding of a size of the memory allocation; and generating a set of compiled instructions which, when executed, enable access to a physical address associated with a virtual address between the first boundary and the second boundary.
