Oh, I forgot about how far function calls are done on powerpc.
Yes, that will suck.
Is there some way to map all of the modules in the low 32-bits and
thus aovid the trampolines? The powerpc call instruction can cover
4GB like on sparc right?
Actually, I remember there is some linkage register that has
to be setup on powerpc with the code model you guys use, is
that the problem?
