There are apparently some constructs that trigger MIPS/Dwarf backend
bugs in GCC when it tries to make debugging symbols.  It might be that
you could add -g back to the Makefile.common after building Swarm so as
to get debugging symbols for your model, at least.

That's really the extent of what I know.  Since I don't use IRIX, and
no SDG members (as of yet) use IRIX, I haven't made fixing this a priority
(or for that matter even constructing a useful bug report).

Just if you want to use the Java layer.

Windows has a different model for dynamically loading code, but yes,
if you want to use the Java layer all of the needed software must be
organized as shared libraries.

Shared libraries also mean 1) you can apply bug fixes to Swarm without
re-linking your model, 2) executables are smaller, and 3) linking is faster.
