104 /* There are basically two options that control the tagging scheme:
105 - USE_LISP_UNION_TYPE says that Lisp_Object should be a union instead
107 - USE_LSB_TAG means that we can assume the least 3 bits of pointers are
108 always 0, and we can thus use them to hold tag bits, without
109 restricting our addressing space.
111 If USE_LSB_TAG is not set, then we use the top 3 bits for tagging, thus
112 restricting our possible address range. Currently USE_LSB_TAG is not
113 allowed together with a union. This is not due to any fundamental
114 technical (or political ;-) problem: nobody wrote the code to do it yet.
116 USE_LSB_TAG not only requires the least 3 bits of pointers returned by
117 malloc to be 0 but also needs to be able to impose a mult-of-8 alignment
118 on the few static Lisp_Objects used: all the defsubr as well
