1323 
 
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.  */
