::: HACK ALERT ::: HACK ALERT ::: HACK ALERT ::: HACK ALERT ::: HACK ALERT :::
The JIT is designed to code-generate a function at-a-time. That means that any
pass can only make local changes to its function. Period.
Because the Sparc PreSelection pass claims to be a BasicBlock pass while adding
globals to the Module, it cannot be run with the other passes, because by this
time, the globals have been output already by the JIT, and the addresses of any
globals appearing AFTER this point are not recognized.
However, the PreSelection pass is a requirement for correctness in the Sparc
codegen path, so it MUST be run.
