To run the tests, make sure that your compiler file is called
compiler.scm, and that at the top of that file, you have:
(load "tests-driver.scm") ; this should come first
(load "tests-1.1-req.scm") ; and any other test files you may have.
Also, make sure that your compiler defines the function
emit-program that takes an expression and uses emit to emit the
appropriate instructions.
The tests-driver defines the procedure test-all that will run all
the tests provided, get the output, redirect it to a file stst.s,
and invokes gcc on that file as well as the startup.c file that you
should have written, and the lib.s file that is generated from the
compile-lib thunk, which you'll need to call once and every time you
change the emit-library thunk, which you can define.
The tests-driver is written for [Petite] Chez Scheme 7. You can obtain a copy of Petite Chez Scheme from: http://www.scheme.com
The tests-driver also assumes that you have the GNU C compiler gcc
already setup and added to your pathname. How you do this depends
on your platform. If you have a different C compiler that you wish
to use, you can edit the tests-driver yourself (look for the
definition of the build procedure).
If all is well, then invoking petite on your compiler and typing
(test-all) should run all the tests as in the following sample
transcript.
