Cousins are a group of related constructs in a compiler that perform similar syntactic tasks. They work together to decompose a program into a sequence of smaller units, ultimately enabling the compiler to generate the final executable code.
For example, consider a compiler's statement processing unit (SPU). This unit breaks down the programmer's statements (like "if", "while", "for") into smaller pieces like keywords, operators, and operands. These pieces can then be assembled together to form the complete program structure.
Similarly, the SPU can also handle other constructs like identifiers (variables), operators (arithmetic, logical, etc.), and keywords (reserved words like "if", "while"). These elements are all cousins of each other, meaning they perform similar syntactic roles but have different functionalities.
By understanding and analyzing the cousins of the compiler, we can gain a deeper understanding of how a compiler works and how to build our own compilers. This knowledge can also help us debug compiler errors and identify potential improvements to the compilation process
