Question

The pass numbers for each of the following activities
(i) object code generation
(ii) literals added to literal table
(iii) listing printed
(iv) address resolution of local symbols that occur in a two pass assembler respectively are

• A. 2, 1, 2, 1
• B. 2, 1, 1, 2
• C. 1, 2, 1, 2
• D. 1, 2, 2, 3

Answer 1

The correct option is A 2, 1, 2, 1

A multi-pass compiler is a type of compiler that processes the source code or abstract syntax tree of a program several times. Two-pass compiler, on the first pass checks the syntax of statements and constructs a table of symbols, while on the second pass it actually translates program statements into machine language.
(i) Object code generation - 2
(ii) Literals added to literal table - 1
(iii) Listing printed - 2
(iv) Address resolution of local symbols that occur in a two pass assembler respectively - 1
