+ so we can't tell immediately which offset in
+ objfile->section_offsets we should apply to the variable's
+ address.
+
+ We could certainly find out which section contains the variable
+ by looking up the variable's unrelocated address with
+ find_pc_section, but that would be expensive; this is the
+ function that constructs the partial symbol tables by examining
+ every symbol in the entire executable, and it's
+ performance-critical. So that expense would not be welcome. I'm
+ not sure what to do about this at the moment.
+
+ What we have done for years is to simply assume that the .data
+ section's offset is appropriate for all global and static
+ variables. Recently, this was expanded to fall back to the .bss
+ section's offset if there is no .data section, and then to the
+ .rodata section's offset. */
