The code generation decouples from the other steps of compilation. They are machine independent and include a modular structure. There are multiple advantages to multipass compilers.

A multipass compiler performs additional tasks such as intermediate code generation, machine dependent code optimization and machine independent code optimization. Likewise, in each pass, the code improves until the final pass generates the final code. It reprocesses the entire compilation unit in each sequential pass.Įach pass takes the result of the previous pass as the input and creates an intermediate output. It converts the program into one or more intermediate representations in steps between source code and machine code. multiple times while generating intermediate code after each stage. What is Multipass CompilerĪ multipass compiler makes the source code go through parsing, analyzing, generating, etc. Moreover, there is no intermediate code generation. Overall, single pass compiler does not optimize the code.

Finally, the code generator generates the target code. Then, the syntactical analysis determines the language constructs described by the grammar. It represents the syntax and legal statements of the language. Every programming language has a grammar. First, the lexical analysis scans the source code and divides it into tokens. Main stages of single pass compiler are lexical analysis, syntactical analysis and code generator. It immediately translates each code section into its final machine code. In other words, it allows the source code to pass through each compilation unit only once. A single pass compiler makes a single pass through the source text, parsing, analyzing, and generating code only once. There are a number of stages in the compilation process. – Comparison of Key Differences Key Terms What is the Difference Between Single Pass and Multipass Compiler

A compiler is a software that converts source code into machine code, and single pass and multipass compiler are two types of compilers. Therefore, it is necessary to convert the source code into a machine-understandable machine code. However, the computer does not understand these instructions. Usually, programmers write programs using high-level programming languages. The main difference between single pass and multipass compiler is that a single pass compiler is a compiler that passes the source code through each compilation unit only once while a multipass compiler separates compilation into multiple passes, where each pass would continue with the result of the previous pass.Ī computer program is a set of instructions for the computer to perform a certain task.
