| George Rimar | 6fdac3b | 2018-07-18 08:19:58 +0000 | [diff] [blame] | 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. |
