Quiz – Code Gen Bridging Concepts

Last week I introduced the idea of the Bridging Concept to help with compilation from a modern programming language to a modern computer architecture. Question: 1. Explain what a bridging concept is for compilation and why it is important. 2. What is the base + offset bridging concept, and what difficulty does it help resolve in compilation. 3. Give an example of the application of the base +

• ffset bridging concept.

You can answer these in any order and cross- reference, but please number them properly.

Project 2 – Code Generation

• Now will generate assembler that will

execute

• A subset of Oberon from Project 1
• No reals, no FOR loop, …
• Project will be graded on:
• a. running compiler on input Oberon programs
• b. running generated assembler programs
• c. comparing output with our expected output

Project 2 Question Sharing

• Turn to a neighbor and discuss something

about the Code Gen project

• Then share with class
• We’ll discuss
