I work for the Motorola compiler group. We use PlumHall (C, C++,
Fortran), Spec92, Spec95, Nullstone, Linpack, Stanford Integer
Benchmark and Bytemarks (did I miss any?). We make regression tests
for any bug that makes it into the bug reporting system - especially
bugs that come from external users. The regression suite is (I think)
several thousand cases long. We run the whole shebang on every minor
internal release.

In short, we throw the kitchen sink at the compiler.
Beta testers still find bugs with amazing ease.
