We have a testsuite available. See the fpc/tests/ directory in cvs or 
fpc.zip. This testsuite contains a lot of basic tests for the codegenerator 
and all reported bugs that are reproducable in non-interactive test programs.

The testsuite is run daily for Linux-i386 and the results can be viewed 
online at http://www.freepascal.org/cgi-bin/testsuite.cgi
