sections generated by the assembler. DWARF 2 sections generated by
other tools will be unaffected by this setting.
@item DWARF2_ADDR_SIZE (@var{bfd})
@cindex DWARF2_ADDR_SIZE
It should return the size of an address, as it should be represented in
debugging info. If you don't define this macro, the default definition uses
the number of bits per address, as defined in @var{bfd}, divided by 8.
