WebLoad instructions in a program can fall into three categories: (a) constant address, (b) striding, and (c) irregular. Constant address loads are loads whose virtual address does not change over multiple dynamic instances of the load (for e.g., global variables and stack accesses). Striding loads are those with successive virtual addresses
