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