INSTRUCTIONS

To run some of the unit tests, you will need Nik Clayton's libtap library
installed. You can get it from http://github.com/pozorvlak/libtap.

If you have redo installed (http://github.com/apenwarr/redo) then you can build tcc and run the tests by typing

    redo

from the project root directory. If not, you can build tcc and run the tests by
typing

    ./do

but this does not support incremental builds. You may run the tests without rebuilding tcc by typing

    prove -l
