Generation of intermediate code based on an abstract machine model is ...
Explanation:
Intermediate code is code that is generated by a compiler between the source code and the target code. It is an abstraction of the target machine's code and is used to make it easier to translate the source code into machine code. The intermediate code is generally optimized and platform-independent, which makes it easier to port the compiler front end to different platforms.
The use of an abstract machine model in the generation of intermediate code has several advantages:
1. Easier implementation of lexical analysis and syntax analysis: The abstract machine model provides a simplified representation of the target machine's instruction set, making the implementation of the lexical and syntax analysis stages of the compiler easier.
2. Syntax-directed translations: Intermediate code generation can be done using syntax-directed translation techniques, which facilitates the construction of compilers.
3. Enhanced portability: The use of intermediate code makes it easier to port the front end of the compiler to different platforms. Since the intermediate code is platform-independent, only the back end of the compiler needs to be modified to generate code for different target machines.
4. Direct generation of code for real machines: Although it is possible to generate code for real machines directly from high-level language programs, the use of an abstract machine model provides a layer of abstraction that makes the process easier and more efficient.
Therefore, option C is the correct answer.
