What is the purpose of intermediate representation?
An intermediate representation (IR) is the data structure or code used internally by a compiler or virtual machine to represent source code. An IR is designed to be conducive for further processing, such as optimization and translation.
What is intermediate object code?
What is intermediate code? Ans: During the translation of a source program into the object code for a target machine, a compiler may generate a middle-level language code, which is known as intermediate code or intermediate text. The complexity of this code lies between the source language code and the object code.
What is the role of code generator?
Code generator converts the intermediate representation of source code into a form that can be readily executed by the machine. A code generator is expected to generate the correct code. Designing of code generator should be done in such a way so that it can be easily implemented, tested and maintained.
What is the importance of intermediate code?
The intermediate code keeps the analysis portion same for all the compilers that’s why it doesn’t need a full compiler for every unique machine. Intermediate code generator receives input from its predecessor phase and semantic analyzer phase. It takes input in the form of an annotated syntax tree.
What are the characteristics of intermediate code?
If we generate machine code directly from source code then for n target machine we will have n optimisers and n code generators but if we will have a machine independent intermediate code, we will have only one optimiser. Intermediate code can be either language specific (e.g., Bytecode for Java) or language.
Which of the following technique can be used as intermediate code generation?
Discussion Forum
| Que. | Which of the following technique can be used as intermediate code generation? |
|---|---|
| b. | Quadruples |
| c. | Both a and b |
| d. | None of these |
| Answer:Postfix notation and three address codes |
What is meant by code generation?
Code generation is a mechanism where a compiler takes the source code as an input and converts it into machine code. Code generation is generally considered the last phase of compilation, although there are multiple intermediate steps performed before the final executable is produced.
What is the need for intermediate code generation ICG )?
Intermediate code is simple enough to be easily converted to any target code. So ICG reduces the overhead of target code generation. Complexity : Intermediate code is Complex enough to represent all complex structure of high-level languages.
What are the three kinds of intermediate representation?
Types of Intermediate Representations Structured (graph or tree-based) Flat, tuple-based, generally three-address code (quadruples) Flat, stack-based. Or any combination of the above three.
What are the properties of intermediate language?
Intermediate Languages
- It should not include too much machine specific detail.
- It provides a separation between front and back ends which helps compiler portability.
- It allows optimization independent of the target machine.
Which of the following is not the intermediate code generation techniques?
∴ Hence the correct answer is Quadruples.
