VMW Assembly Simulator Testsuite

This test-suite has a number of tests useful for testing the accuracy of simulators. It has hello-world programs (source and executables) for a handful of architectures.

I've used the programs within to test m5, qemu, and valgrind.

It can be downloaded here:
Another useful source of test cases is my LL Simulator Tests. It includes a simple benchmark pre-compiled for 20+ different architectures.
