2-Syntax Analyzer (or Parser):
Groups tokens together into syntactic structures..

Answer: The main difference between phases and passes of compiler is that phases are the steps in the compilation process while passes are the number of times the compiler traverses through the source code.
Programmers write computer programs in high-level languages. .

Before the compilation can start, our source code needs to be preprocessed.
After the compilation, our code needs to be converted into executable code to execute on our machine.
These essential tasks are performed by the preprocessor, assembler, Linker, and Loader.
They are known as the Cousins of the Compiler..

Pass : A pass refers to the traversal of a compiler through the entire program.
Phase : A phase of a compiler is a distinguishable stage, which takes input from the previous stage, processes and yields output that can be used as input for the next stage.
A pass can have more than one phase..

Symbol Table is an important data structure created and maintained by the compiler in order to keep track of semantics of variables i.e. it stores information about the scope and binding information about names, information about instances of various entities such as variable and function names, classes, objects, etc..
How do you group phases of compiler?
Compiler passes
Several phases can be grouped into one single pass and the activities of these phases are interleaved during the pass.
For example, lexical analysis, syntax analysis, semantic analysis and intermediate code generation might be grouped into one pass.Feb 12, 2017.
What are the phases of a compiler cousins of the compiler?

After the compilation, our code needs to be converted into executable code to execute on our machine.

What are the phases of compiler design?
The phases of a compiler represent the sequential stages through which source code is transformed into executable code.
These phases include lexical analysis, parsing, semantic analysis, optimization, code generation, and code optimization..
What is grouping of phases in compiler design?
Several phases are grouped together to a pass so that it can read the input file and write an output file.
One-Pass – In One-pass all the phases are grouped into one phase.Feb 10, 2023.
Which tool is used for grouping of characters in the compiler?
This process is performed by a tool called a lexical analyzer or scanner.
The main task of a lexical analyzer is to group the input characters into meaningful sequences, which are called tokens.
These tokens can then be used by the parser for further analysis..
Why compiler design is divided into phases?
Compiler operates in various phases each phase transforms the source program from one representation to another.
Every phase takes inputs from its previous stage and feeds its output to the next phase of the compiler.Sep 21, 2023.
Why is it necessary to group the phases of compiler?
The compiler is essential for tuning a program successfully, and the phases are responsible for logical dealing.
Phases are grouped to reduce the number of passes, and this saves time for the program while it is running for interpreting the inputs.Sep 18, 2020.
Why is it preferred to keep front end phases and back end phases into different pass?
There are several reasons why.
First, since the code is divided into two parts, you can optimize the code faster.
Secondly, you can increase resources for the front-end and back-end at a separate pace since the back-end would need to be ramped up at a relatively faster pace as you grow. 2..
