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