Is there a regression test suite?

Hello

Is there a set of regression test for Inferno ?

Compiling it by different compiler for different platforms without a
test suite can produce long-lived bugs.
I have tried to compile Inferno for openmoko (ARM/Linux) using gcc-4.3
and found a few bugs there, although Inferno and most of applications
can start on that platform.
For example,
conversion between int and big types (as well as '%b' in sys->sprint)
does not work correctly because GCC assume stack is 8 byte aligned,
registers used by jitted code are not saved in stack so jit does not
work at all,
etc
I guess there are a lot of bugs remainded and some test suite may help
to find them.
