https://sourceware.org/bugzilla/show_bug.cgi?id=23389 --- Comment #2 from Nick Clifton --- (In reply to H.J. Lu from comment #1) > How are separate debuginfo files are encoded in the executable? Ah - there are three different ways 1. In a .gnu.debuglink section 2. In a .gnu.altdebuglink section and 3. Via the DW_AT_GNU_dwo_name, DW_AT_dwo_name, DW_AT_GNU_dwo_id and DW_AT_comp_dir DWARF attributes. There is code in binutils/dwarf.c that handles all three, plus some support in bfd/opncls.c as well. Then there is the problem of locating these files, even given the information from these places. There are lots of places to look and different execution environments can provide different, extra, locations as well. A bit of nightmare really.
