1. In semantic analysis, the global variables declared in the input source are converted to symbol table entries. How are the symbol table entries translated into corresponding declarations in x86 assembly language by the target code generator? Illustrate by example for (a) simple variables (b) arrays.
2. How do you generate target code for arithmetic TAC operators in a template-based code generation approach? Illustrate with examples for (a) ADD (b) SUB (c) MUL (d) DIV (e) UMINUS.
