A set of tests and miscellaneous useful files for the Compiler Construction course at the University of Amsterdam.
We provide a test suite consisting of dozens of edge cases that you might not be aware of.
The easiest way to install the test suite, would be to add it as a subdirectory to your own repository. To do this, use the following code from the root of your own project repository:
git submodule add [email protected]:StephenSwat/Compiler-Construction-Starter-Kit.git test
git commit -m 'Add the compiler construction starter kit'
You can add a rule to your Makefile to easily run the test files for you. The rule should look something like the following:
test: civicc
@test/test.sh
Then, run make test
to execute the full suite of tests.
To make developing your compiler easier, you might want to be able to just call the name of your compiler in stead of having to give its path. One way of doing this is as follows:
mkdir ~/.bin
echo 'PATH=$PATH:~/.bin' >> ~/.bashrc
ln -s [path to your compiler executabe] ~/.bin/my_compiler
You should then extract the compiler toolchain (civcc
, civas
, civrun
and
civvm
) to the ~/.bin
directory, which should allow you to simply run the
commands civcc
, my_compiler
(giving your compiler a creative name is
encouraged), etc.
After installing, fill in the file test/test.sh
with the details of your
compiler. Enter the name of your compiler, the reference compiler, the assembler
and the virtual machine.
If you enable the CHECK_OUTPUT
flag, the test suite will also compare the
output of your code after insertion into the virtual machine to the output of
the reference compiler. This only makes sense if you are already generating
byte code!
To run the suite, navigate to the test directory and execute the test script
using a command such as ./test.sh
. If you have set everything up correctly,
you should get output similar to the following:
Running failure tests...
Test fail/embargo.cvc should not succeed!
Running success tests...
Test success/array_size.cvc should not fail!
Test success/local_array.cvc should not fail!
Test success/print_matrix.cvc should not fail!
Test success/queens.cvc should not fail!
Test success/quicksort.cvc should not fail!
Test success/short_circuit.cvc should not fail!
Test success/short_circuit_or.cvc should not fail!
Passed 53 out of 61 tests. Your grade: 8.6.
There are some blatant issues with the framework provided. Mainly, the C preprocessor is broken and secondly, the framework wastes a lot of memory by using strucs where is should use unions. Provided with this starter kit are patches that fix these issues. To fix the problems, run the following from your project root:
(cd src/; patch -p1 -i ../test/patches/fix_unions.diff)
(cd src/; patch -p1 -i ../test/patches/fix_preprocessor.diff)
To update the test suite submodule, run the following command:
git submodule foreach git pull origin master
You are encouraged to add your own tests to the suite. Granted that you insert them into the right directory, the suite should adapt to any number of tests. For reference, the reference compiler should score a perfect score. Please make a pull request to share your tests with others so we can all profit from your work!
