871 | ||
872 | The implementation is loosely based on the SOM code and made up | |
873 | of 3 distinct phases: | |
874 | ||
875 | 1. When the VMS object is opened and parsed, the number and the size | |
876 | of the relocations are computed for all sections. This makes it | |
877 | possible to know upfront both which sections have no relocs and | |
878 | the size of the reloc buffers for the other sections, at virtually | |
879 | no cost for consumers that don't care about relocs at all. | |
880 | ||
881 | 2. When vms_slurp_reloc_table is invoked for the first time on a section | |
882 | with relocs, the object is traversed and all the reloc information | |
883 | is saved in per-section reloc buffers. It would be very inefficient | |
884 | to scan the whole file on each invocation, so we slurp for all the | |
885 | sections at once. | |
886 | ||
887 | 3. On subsequent invocations of vms_slurp_reloc_table, the relocs for the | |
888 | specified section are fetched from the buffer, decoded and internalized. | |
889 | The buffer is then freed since the internalized relocs are attached to | |
890 | the section, turning additional invocations of vms_slurp_reloc_table | |
891 | on the same section into no-ops. | |
892 | ||
893 | Since VMS objects have very few sections, it could be profitable to merge | |
894 | phase #2 and phase #3, i.e. to decode and internalize the relocs for all | |
895 | the sections at once. The current implementation is more elegant. */ | |
