In a relocatable file, a debug section refers to a location in a program section by way of a relocated location. A reference from a debug section to a location in a program section has the following format:
<debug_section_index
,debug_section_offset
>, <program_section_index
,program_section_offset
>
During static linking the pair of
values
is reduced to single value, the execution address. This is ambiguous
in the presence of overlaid sections.program
To resolve this ambiguity, use this option to output a .ARM.debug_overlay
section
of type SHT_ARM_DEBUG_OVERLAY = SHT_LOUSER + 4
containing
a table of entries as follows:
debug_section_offset
, debug_section_index
, program_section_index
