   1 ## many-sections.elf-x86_64 is a file that was generated to simulate
   2 ## an object with more than ~65k sections. When an ELF object
   3 ## has SHN_LORESERVE (0xff00) or more sections, its e_shnum field
   4 ## should be zero and sh_size of the section header at index 0 is used
   5 ## to store the value. If the section name string table section index is
   6 ## greater than or equal to SHN_LORESERVE, then e_shstrndx field
   7 ## should have the value of SHN_XINDEX and sh_link of the section header
   8 ## at index 0 is used to store the value.
   9 ##
  10 ## many-sections.elf-x86_64 has few sections to save disk
  11 ## space, but its e_shnum, e_shstrndx, sh_size and sh_link fields are set
  12 ## according to the above description, so that we can test the dumper.
