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 input SPARC SPARC foo.obe assembler executable grading grading your compiler cc execute your compiler cc execute program program

Project 2 Question Sharing • Turn to a neighbor and discuss something about the Code Gen project • Then share with class • We’ll discuss
