Symbol values
Symbol table entries for different object file types have slightly
different interpretations for the st_value member.
-
In relocatable files, st_value holds alignment constraints
for a symbol whose section index is SHN_COMMON.
-
In relocatable files, st_value holds a section offset for
a defined symbol. st_value is an offset from the beginning
of the section that st_shndx identifies.
-
In executable and shared object files, st_value holds a
virtual address. To make these files' symbols more useful for the
dynamic linker, the section offset (file interpretation) gives way
to a virtual address (memory interpretation) for which the section
number is irrelevant.
Although the symbol table values have similar meanings for different
object files, the data allows efficient access by the appropriate
programs.
