You could try compiling programs from the llvm test-suite and see if they
work, or you could write lit tests.  See test/CodeGen/X86 for examples.

My personal experience writing a LLVM backend for Octasic is that a good
commercial C/C++ compiler validation test suite will catch the most bug.
Especially corner cases.

If you can't afford one then you could try the GCC torture test.
