The bit order of the has_vec and longtbtable bits in the traceback table generated by the XL compiler has flipped since v13.1. This is different from the definition is the AIX header debug.h. The wyvern compiler and the unwinder use the bit order as the v13.1 compiler and higher. It was decided that the wyvern compiler should follow the bit order as defined by the AIX header.
