What are different data structures used in two pass assembler?
Answers
Assembler algorithm as well as data structures are the different data structures used in two pass assembler.
These are simple assembler uses two major internal data structure.
Even the operation code table (optab) as well as the symbol table (symtab).
On the other hand optab is used to look up mnemonic operation codes as well as this will translate them to their machine language equivalents.
Answer:
Operation Table and Symbol table
Explanation:
A computer or other programmable devices can be programmed using Assembly Language, a low-level programming language.
The machine code instructions of the architecture are closely related to the assembly language.
A translator, or assembler, converts an assembly programmed into a regular machine language programmed.
In essence, the assembler reads each line of the programmed and produces machine code for that instruction. Typically, the assembler produces the object code in memory for immediate execution.
Your source code is parsed once, and you are then finished.
Let's now examine how a two pass assembler functions.As stated, the one-pass assembler is unable to resolve data symbol forward references.
All data symbols must first be defined, otherwise it will not work.
