132 | /***** Select the tagging scheme. *****/ | |
133 | /* There are basically two options that control the tagging scheme: | |
134 | - NO_UNION_TYPE says that Lisp_Object should be an integer instead | |
135 | of a union. | |
136 | - USE_LSB_TAG means that we can assume the least 3 bits of pointers are | |
137 | always 0, and we can thus use them to hold tag bits, without | |
138 | restricting our addressing space. | |
139 | ||
140 | If USE_LSB_TAG is not set, then we use the top 3 bits for tagging, thus | |
141 | restricting our possible address range. Currently USE_LSB_TAG is not | |
142 | allowed together with a union. This is not due to any fundamental | |
143 | technical (or political ;-) problem: nobody wrote the code to do it yet. | |
144 | ||

146 | malloc to be 0 but also needs to be able to impose a mult-of-8 alignment | |
