|
|---|
| 131 | The \CFA (Cforall) programming language is an evolutionary refinement of
|
|---|
| 132 | the C programming language, adding modern programming features without
|
|---|
| 133 | changing the programming paradigms of C.
|
|---|
| 134 | One of these modern programming features is more powerful error handling
|
|---|
| 135 | through the addition of an exception handling mechanism (EHM).
|
|---|
| 136 |
|
|---|
| 137 | This thesis covers the design and implementation of the \CFA EHM,
|
|---|
| 138 | along with a review of the other required \CFA features.
|
|---|
| 139 | The EHM includes common features of termination exception handling,
|
|---|
| 140 | which abandons and recovers from an operation,
|
|---|
| 141 | and similar support for resumption exception handling,
|
|---|
| 142 | which repairs and continues with an operation.
|
|---|
| 143 | The design of both has been adapted to utilize other tools \CFA provides,
|
|---|
| 144 | as well as fit with the assertion based interfaces of the language.
|
|---|
| 145 |
|
|---|
| 146 | The EHM has been implemented into the \CFA compiler and run-time environment.
|
|---|
| 147 | Although it has not yet been optimized, performance testing has shown it has
|
|---|
| 148 | comparable performance to other EHMs,
|
|---|
| 149 | which is sufficient for use in current \CFA programs.

|
|---|
| 157 |
|
|---|
| 158 | As is tradition and his due, I would like to begin by thanking my
|
|---|
| 159 | supervisor Peter Buhr. From accepting me in a first place,
|
|---|
| 160 | to helping me run performance tests, I would not be here without him.
|
|---|
| 161 | Also if there was an ``artist" field here he would be listed there as well,
|
|---|
| 162 | he helped me a lot with the diagrams.
|
|---|
| 163 |
|
|---|
| 164 | I would like to thank the readers
|
|---|
| 165 | Gregor Richards and Yizhou Zhang
|
|---|
| 166 | for their feedback and approval.
|
|---|
| 167 | The presentation of the thesis has definitely been improved with their
|
|---|
| 168 | feedback.
|
|---|
| 169 |
|
|---|
| 170 | I also thank the entire Cforall Team who built the rest of the
|
|---|
| 171 | \CFA compiler. From the existing features I used in my work, to the
|
|---|
| 172 | internal tooling that makes further development easier and the optimizations
|
|---|
| 173 | that make running tests pass by quickly.
|
|---|
| 174 | This includes: Aaron Moss, Rob Schluntz, Thierry Delisle, Michael Brooks,
|
|---|
| 175 | Mubeen Zulfieqar \& Fangren Yu.
|
|---|
| 176 |
|
|---|
| 177 | And thank-you Henry Xue, the co-op student who
|
|---|
| 178 | converted my macro implementation of exception declarations into
|
|---|
| 179 | the compiler features presented in this thesis.
|
|---|
| 180 |
|
|---|
| 181 | Finally I thank my family, who are still relieved I learned how to read.
