Hi Eli,
Thanks for your reply. If I add -force-interpreter to lli, then it seems
that it can not run external function like printf or malloc. Is there any
easy way to solve this problem?

Hi Eli,
I think the llvm configure has already configured with ffi.
../llvm-2.6/configure -help | grep ffi
--enable-libffi Check for the presence of libffi (default is YES)
In addition, the printf() can work in program, reflecting that libffi is
working, right?
How can I make Interpreter work with getpid(), fork(), and clone()?
