Describe the instruction selection process for a given TAC snippet: t3 = t1 * t2; IF t3 > 50 GOTO label.
💡 Hint: Break down the TAC into manageable parts for each assembly instruction related to the operations.
Given a more complex TAC involving arrays, like A[i] = t1 + t2, outline the assembly translation details.
💡 Hint: Pay attention to how arrays and addressing work in assembly to specify where results are stored.
