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