## Here we simulate an object with more than ~65k sections and check how we dump it.
|
|
## When an ELF object has SHN_LORESERVE (0xff00) or more sections, its e_shnum field
|
|
## should be zero and sh_size of the section header at index 0 is used
|
|
## to store the value. If the section name string table section index is
|
|
## greater than or equal to SHN_LORESERVE, then e_shstrndx field
|
|
## should have the value of SHN_XINDEX and sh_link of the section header
|
|
## at index 0 is used to store the value.
