132 /* There are basically two options that control the tagging scheme:
133 - NO_UNION_TYPE says that Lisp_Object should be an integer instead
135 - USE_LSB_TAG means that we can assume the least 3 bits of pointers are
136 always 0, and we can thus use them to hold tag bits, without
137 restricting our addressing space.
139 If USE_LSB_TAG is not set, then we use the top 3 bits for tagging, thus
140 restricting our possible address range. Currently USE_LSB_TAG is not
141 allowed together with a union. This is not due to any fundamental
142 technical (or political ;-) problem: nobody wrote the code to do it yet.
144 USE_LSB_TAG not only requires the least 3 bits of pointers returned by
145 malloc to be 0 but also needs to be able to impose a mult-of-8 alignment
146 on the few static Lisp_Objects used: all the defsubr as well
