What are the major topics in the returned docs?. Code Generation. Use registers during execution. Whenever possible, perform computation in registers. Memory load/store are much more expensive. Need to determine the best register allocation. For a given number of registers, minimize the number of spills. P-. 1. CSE P501 – Compiler Construction. Register allocation . constraints.

Addressing modes help us to understand the types of operands and the way they are accessed while executing an instruction. . What are we going to study?. Addressing modes.
