DESCRIPTION
- Here is a description of each of the fields within an <<arelent>>:
-
- o <<sym_ptr_ptr>>
-
- The symbol table pointer points to a pointer to the symbol
- associated with the relocation request. It is the pointer
- into the table returned by the back end's
- <<canonicalize_symtab>> action. @xref{Symbols}. The symbol is
- referenced through a pointer to a pointer so that tools like
- the linker can fix up all the symbols of the same name by
- modifying only one pointer. The relocation routine looks in
- the symbol and uses the base of the section the symbol is
- attached to and the value of the symbol as the initial
- relocation offset. If the symbol pointer is zero, then the
- section provided is looked up.
-
- o <<address>>
-
- The <<address>> field gives the offset in bytes from the base of
- the section data which owns the relocation record to the first
- byte of relocatable information. The actual data relocated
- will be relative to this point; for example, a relocation
- type which modifies the bottom two bytes of a four byte word
- would not touch the first byte pointed to in a big endian
- world.
