147 | - USE_LISP_UNION_TYPE says that Lisp_Object should be a union instead |
148 | of an integer. | |
b9466edb SM |
149 | - USE_LSB_TAG means that we can assume the least 3 bits of pointers are |
150 | always 0, and we can thus use them to hold tag bits, without | |
151 | restricting our addressing space. | |

154 | restricting our possible address range. Currently USE_LSB_TAG is not | |
155 | allowed together with a union. This is not due to any fundamental | |
156 | technical (or political ;-) problem: nobody wrote the code to do it yet. | |
157 | ||
158 | USE_LSB_TAG not only requires the least 3 bits of pointers returned by | |
159 | malloc to be 0 but also needs to be able to impose a mult-of-8 alignment | |
