What is the significance of “.note.ABI-tag” section in ELF?

I see a .note.ABI-tag section when I objdump -h <binary> on a ELF file.



As per the ELF man page:



   .note.ABI-tag

             This section is used to declare the expected run-time ABI

             of the ELF image.  It may include the operating system name

             and its run-time versions.  This section is of type

             SHT_NOTE.  The only attribute used is SHF_ALLOC.



  1. Is this section necessary?

  2. What could be the side effects removing this section?

  3. How to remove this section (a gcc flag) from ELF?

          9 $begingroup$ This question already has an answer here: What happens if we put together a proton and an antineutron? 2 answers Is it theoretically possible to make a "deuterium" atom containing a proton and an antineutron in its nucleus? Would the strong nuclear force cause attraction between a proton and an antineutron? Would such a nucleus be stable, or would the proton somehow annihilate the antineutron when close enough? nuclear-physics antimatter share | cite | improve this question asked yesterday
