3address

3address refers to a specific type of intermediate representation (IR) used in compilers. In this representation, each instruction has at most three operands. Typically, these operands are source registers or memory locations, and a destination register. This structure makes 3address code relatively simple to generate and analyze, facilitating various compiler optimizations. A common format is destination = source1 operator source2. For instance, an addition operation might be represented as `a = b + c`. This contrasts with other IRs that might have more operands per instruction or a different operand structure. The simplicity of 3address code allows for straightforward translation into machine code. It's a fundamental concept in compiler design and is widely used as a stepping stone between high-level programming languages and the machine's instruction set. The limited number of operands per instruction helps in managing register allocation and instruction scheduling.
