Best answer 48 48 votes Correct Option: B The functions performed in pass $1$ and pass $2$ in $2$ pass assembler are Pass $1$ Assign addresses to all statements in the program. Save the values assigned to all labels for use in pass $2$ Perform some processing of assembler directives. Pass $2$ Assemble instructions. Generate data values defined by BYTE, WORD etc. Perform processing of assembler directives not done during pass $1$.

8 8 votes i think ans should be B. literals added to literal table is done in lexical analysis phase, so possible in 1 pass. and a is back end activity so can not in 1 pass. d is back end activity but it is in 2 pass assembler. so only 1 pass required. hence B jayendra answered Jan 7, 2015 • edited Jan 7, 2015 by jayendra jayendra comment Share Follow See all 2 Comments 2 2 Comments reply Mudrakola Karthik 3 commented Dec 29, 2017 reply Follow flag address resolution is done by the loader.it not done by assembler plz explain why option d is done in 1st pass of assembler 3 3 replyShare Aspirant commented Jan 6, 2018 reply Follow flag What is back end activity ? plz explain. 0 0 replyShare Please log in or register to add a comment.
