CS712/CS812
Project Phase 3
Fall 2017
Due Sunday November 12

Add features to your UNH Go compiler:

  1. (50 points) This will be a re-evaluation of the first three bullet items from the Phase 1 assignment and the second and third bullet items from Phase 2.

  2. (10 points) Declaration of pointer and struct types. You do not need to support struct field tags, blank field names, or embedded fields. I will use the symbol table dump to evaluate your handling of declarations, so be sure that the dump is correctly functioning.

  3. (10 points) Pointer and struct expressions, including assignment, parameters, field selectors and the built-in function "new".

  4. (10 points) The address operation ("&"), pointer indirection ("*") the predefined identifier "nil", pointer comparisons and struct comparisons.

  5. (20 points) Method declarations, method calls and method expressions. You may assume that the receiver will be of the form *T, where T is a type name. You do not need to implement method values.

You can allow nil pointer dereferences to segfault, rather than causing a Go "panic".

There are some initial test files available on agate in ~cs712/public/tests/phase3.

To get full credit, your code must be adequately documented and structured. If I can't easily read and understand your code, you may lose points.

You must give me back the system in the same form that I gave it to you. I must be able to install it and run it in the exact same way as when it was delivered to you. I would also like you to keep the source code organized in the same directory hierarchy. If you fail to do this, a significant deduction will be made to your grade.

Note that there is a script, distribute.sh, in ugo/bin, which will generate a tar file for you. This tar file is what I require you to submit to me for grading.

To turn in this assignment, type (on agate.cs.unh.edu):
~cs712/bin/submit phase3 ugo.tar

Submissions can be checked by typing (on agate.cs.unh.edu):
~cs712/bin/scheck phase3

The assignment is due on Sunday November 12. There is a grace period to 8am on Monday November 13 when no late penalty will be assigned. Submissions between 8am November 13 and 8am November 14 will have a late penalty of 10 points. Submissions between 8am November 14 and 8am November 15 will have a late penalty of 30 points. No submissions will be accepted after 8am on Wednesday November 15.

Remember: you are expected to do your own work on this assignment.
