Challenge Problems

Push your limits with challenges.

Question 1

Describe the instruction selection process for a given TAC snippet: t3 = t1 * t2; IF t3 > 50 GOTO label.

πŸ’‘ Hint: Break down the TAC into manageable parts for each assembly instruction related to the operations.

Question 2

Given a more complex TAC involving arrays, like A[i] = t1 + t2, outline the assembly translation details.

πŸ’‘ Hint: Pay attention to how arrays and addressing work in assembly to specify where results are stored.
