Q: What is the purpose of register allocation in code generation?
Solution:
The purpose of register allocation in code generation is to assign variables to CPU registers to improve execution speed.
Steps: 5
Show Steps
Step 1: Understand that a CPU has a limited number of registers, which are small storage locations used for quick data access.
Step 2: Recognize that when a program runs, it uses variables to store data.
Step 3: Realize that accessing data from registers is much faster than accessing it from main memory.
Step 4: Learn that register allocation is the process of deciding which variables should be stored in the CPU registers.
Step 5: Understand that effective register allocation can make a program run faster by reducing the time it takes to access data.
