1324 | ||
1325 | The implementation is loosely based on the SOM code and made up | |
1326 | of 3 distinct phases: | |
1327 | ||
1328 | 1. When the VMS object is opened and parsed, the number and the size | |
1329 | of the relocations are computed for all sections. This makes it | |
1330 | possible to know upfront both which sections have no relocs and | |
1331 | the size of the reloc buffers for the other sections, at virtually | |
1332 | no cost for consumers that don't care about relocs at all. | |
1333 | ||
1334 | 2. When vms_slurp_reloc_table is invoked for the first time on a section | |
1335 | with relocs, the object is traversed and all the reloc information | |
1336 | is saved in per-section reloc buffers. It would be very inefficient | |
1337 | to scan the whole file on each invocation, so we slurp for all the | |
1338 | sections at once. | |
1339 | ||
1340 | 3. On subsequent invocations of vms_slurp_reloc_table, the relocs for the | |
1341 | specified section are fetched from the buffer, decoded and internalized. | |
1342 | The buffer is then freed since the internalized relocs are attached to | |
1343 | the section, turning additional invocations of vms_slurp_reloc_table | |
1344 | on the same section into no-ops. | |
1345 | ||
1346 | Since VMS objects have very few sections, it could be profitable to merge | |
1347 | phase #2 and phase #3, i.e. to decode and internalize the relocs for all | |
1348 | the sections at once. The current implementation is more elegant. */ | |
