78 | * Non-objects -- meaning that the tag-related macros don't apply to them | |

80 | * | |
81 | * Immediates -- meaning that the variable contains an entire Scheme object. | |

89 | * | |
90 | * All immediates and non-immediates must have a 0 in bit 0. Only non-object | |

95 | * or the header of a struct. But whenever an SCM variable holds a normal Scheme | |
96 | * value, bit 0 is 0. | |

132 | * | |
133 | * | |
134 | * 100 --- IMMEDIATES | |
135 | * | |
136 | * Looking at the seven final bits of an immediate: | |
137 | * | |
138 | * 0000-100 short instruction | |
139 | * 0001-100 short instruction | |
140 | * 0010-100 short instruction | |
141 | * 0011-100 short instruction | |
142 | * 0100-100 short instruction | |
143 | * 0101-100 short instruction | |
144 | * 0110-100 various immediates and long instructions | |
145 | * 0111-100 short instruction | |
146 | * 1000-100 short instruction | |
147 | * 1001-100 short instruction | |
148 | * 1010-100 short instruction | |
149 | * 1011-100 short instruction | |
150 | * 1100-100 short instruction | |
151 | * 1101-100 short instruction | |
152 | * 1110-100 immediate characters | |
153 | * 1111-100 ilocs | |
154 | * | |
155 | * Some of the 0110100 immediates are long instructions (they dispatch | |
156 | * in two steps compared to one step for a short instruction). | |
157 | * The two steps are, (1) dispatch on 7 bits to the long instruction | |
158 | * handler, (2) dispatch on 7 additional bits. | |
159 | * | |
160 | * One way to think of it is that there are 128 short instructions, | |
161 | * with the 13 immediates above being some of the most interesting. | |
162 | * | |
163 | * Also noteworthy are the groups of 16 7-bit instructions implied by | |
164 | * some of the 3-bit tags. For example, closure references consist | |
165 | * of an 8-bit aligned address tagged with 011. There are 16 identical 7-bit | |
166 | * instructions, all ending 011, which are invoked by evaluating closures. | |
167 | * | |
168 | * In other words, if you hand the evaluator a closure, the evaluator | |
169 | * treats the closure as a graph of virtual machine instructions. | |
170 | * A closure is a pair with a pointer to the body of the procedure | |
171 | * in the CDR and a pointer to the environment of the closure in the CAR. | |
172 | * The environment pointer is tagged 011 which implies that the least | |
173 | * significant 7 bits of the environment pointer also happen to be | |
174 | * a virtual machine instruction we could call "SELF" (for self-evaluating | |
175 | * object). | |
176 | * | |
177 | * A less trivial example are the 16 instructions ending 000. If those | |
178 | * bits tag the CAR of a pair, then evidently the pair is an ordinary | |
179 | * cons pair and should be evaluated as a procedure application. The sixteen, | |
180 | * 7-bit 000 instructions are all "NORMAL-APPLY" (Things get trickier. | |
181 | * For example, if the CAR of a procedure application is a symbol, the NORMAL-APPLY | |
182 | * instruction will, as a side effect, overwrite that CAR with a new instruction | |
183 | * that contains a cached address for the variable named by the symbol.) | |
184 | * | |
185 | * Here is a summary of tags in the CAR of a non-immediate: | |
186 | * | |
187 | * HEAP CELL: G=gc_mark; 1 during mark, 0 other times. | |
188 | * | |
189 | * cons ..........SCM car..............0 ...........SCM cdr.............G | |
190 | * gloc ..........SCM vcell..........001 ...........SCM cdr.............G | |
191 | * struct ..........void * type........001 ...........void * data.........G | |
192 | * closure ..........SCM code...........011 ...........SCM env.............G | |
193 | * tc7 .........long length....GxxxD1S1 ..........void *data............ | |
194 | * | |
195 | * | |
196 | * | |
197 | * 101 & 111 --- tc7_ types | |
198 | * | |
199 | * tc7_tags are 7 bit tags ending in 1x1. These tags occur | |
200 | * only in the CAR of heap cells. | |
201 | * | |
202 | * SCM_LENGTH returns the bits in "length" (see the diagram). | |
203 | * SCM_CHARS returns the data cast to "char *" | |
204 | * SCM_CDR returns the data cast to "SCM" | |
205 | * TYP7(X) returns bits 0...6 of SCM_CAR (X) | |
206 | * | |
207 | * For the interpretation of SCM_LENGTH and SCM_CHARS | |
208 | * that applies to a particular type, see the header file | |
209 | * for that type. | |
210 | * | |
211 | * TYP7S(X) returns TYP7, but masking out the option bit S. | |
212 | * TYP7D(X) returns TYP7, but masking out the option bit D. | |
213 | * TYP7SD(X) masks out both option bits. | |
214 | * | |
215 | * for example: | |
216 | * D S | |
217 | * scm_tc7_string = Gxxx0101 | |
218 | * scm_tc7_mb_string = Gxxx0111 | |
219 | * scm_tc7_substring = Gxxx1101 | |
220 | * scm_tc7_mb_substring = Gxxx1111 | |
221 | * | |
222 | * TYP7S turns tc7_mb_string into tc7_string and | |
223 | * tc7_mb_substring into tc7_substring. | |
224 | * | |
225 | * TYP7D turns tc7_mb_substring into tc7_mb_string and | |
226 | * tc7_substring into tc7_string. | |
227 | * | |
228 | * TYP7DS turns all string tags into tc7_string. | |
229 | * | |
230 | * Some TC7 types are subdivided into 256 subtypes giving | |
231 | * rise to the macros: | |
232 | * | |
233 | * TYP16 | |
234 | * TYP16S | |
235 | * GCTYP16 | |
236 | * | |
237 | * TYP16S functions similarly wrt to TYP16 as TYP7S to TYP7, | |
238 | * but a different option bit is used (bit 2 for TYP7S, | |
239 | * bit 8 for TYP16S). | |
