The second section of "doc/unrolling.txt" explains the changes that you'll
need to make to "cvm_config.h" to turn on the unroller. The changes for
"cvm.c" are already done. At the top of "unroll.c", you'll need to add the
following two lines just before the "#error" case:
#elif defined(CVM_PPC)
#include "md_ppc.h"
Then fix any compilation bugs that arise. After that, run some simple "Hello
World" style test cases, relax, and watch the pretty segfaults. :-) The
bottom of "unrolling.txt" describes some techniques for debugging.
Once there are no more segfaults and "make check" runs successfully in
pnetlib, then you're in good shape.
Cheers,
Rhys.
