104 always 0, and we can thus use them to hold tag bits, without
105 restricting our addressing space.
107 If USE_LSB_TAG is not set, then we use the top 3 bits for tagging, thus
108 restricting our possible address range. Currently USE_LSB_TAG is not
109 allowed together with a union. This is not due to any fundamental
110 technical (or political ;-) problem: nobody wrote the code to do it yet.
112 USE_LSB_TAG not only requires the least 3 bits of pointers returned by
113 malloc to be 0 but also needs to be able to impose a mult-of-8 alignment
