Assembler Pass 2

Introduction:

Pass 2 of an assembler converts the assembly code into object code using the symbol table and literal table(intermediate) created in Pass 1. In this pass, symbolic addresses are replaced with actual memory addresses. Symbolic opcodes are translated into their numeric equivalents (machine code). Literals, such as constants, are also substituted with their memory addresses. The assembler processes instructions, generating the object code that the machine can execute. This pass ensures that all symbols, opcodes, and literals are resolved, and the program is ready for linking or execution. The final output is a machine-readable object file.
