To identify if the instruction has any memory reference, "memory_ref_char" field needs to be set for specific architecture. Example memory instruction: lwz r10,0(r9)
Here "(" is the memory_ref_char. Set this as part of arch->objdump To get register number and access offset from the given instruction, arch->objdump.register_char is used. In case of powerpc, the register char is "r" (since reg names are r0 to r31). Hence set register_char as "r".
