Hmm, PIC? How's the code generated by a current gcc 2.95.x supported by
SpareMiNT dependent on a memory address that is loaded to? We don't have
VM and so we do relocation by each exec(), right?
In case the binary is made using -fPIC. Do we have to do any relocation at
all?
So with -fPIC we can just resolve symbols across libs/executables and we
are done. This is what ELF loader need to do no matter if the VM is or
is not in use.
Is that correct?
