Nullstone is good to find what is quality of your optimizations and
what optimizations are missed.
As verification of C/C++/Java, I'd recommend Plumhall testsuite
(http://www.plumhall.com). It stresses the compiler very good.
Another testsuite is perennial testsuite (http://www.peren.com).
One interesting useful toolset which tests so called "student" program
is DDT (article about DDT is on
http://www.europe.digital.com/info/DTJT08/DTJT08HM.HTM. You can
download DDT from
http://nar-associates.com/site/sdr/projects/ddt/download/). It finds
bugs which other testsuites usually can not find (but it misses the
most of bugs which other testsuites find). It automatically generates
C tests and can compare the results on different compilers. You can
modify it to tune it to another language, e.g. I used it to find some
bugs (even parser bugs) in Microsoft Fortran 90.
