Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

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.

Challenge 2 Hard

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.
