compiler code coverage

I ran across these awesome coverage reports for llvm:

Anyone interested in seeing how much of a coverage increase is gotten by compiling random programs?

It may be profitable to create a new category of programs in the test suite: random programs that cause otherwise-uncovered parts of the compiler to execute.

Sure!

suite: random programs that cause otherwise-uncovered parts of the
compiler to execute.

Yes, that would be great. However it would be better if they were
bitcode rather than C.
