• This phase of the compiler generates the intermediate code.

• As the name implies, the intermediate code is between high level and machine level language

• The generated intermediate code is called three-address code and this includes a set of instructions resembling assembly language with 3 operands per instruction

• Each of the operands acts like a register.

Properties of intermediate representation:

• Easy to produce

• Easy to translate to the target machine code

Summary of the functions of intermediate code generation:

• Intermediate code is generated from semantic representation of the source code

• Stores the computed values 

• Maintain the order of precedence of the source language

• Holds the correct number of operands for the instruction

• Example- Intermediate code for a=b- c*50

t1 =  inttofloat(50)
t2 =  id3*t1
t3 =  id2 - t2
id1 =   t3
