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