This section describes the Executable and Linking Format (ELF).
For file identification in e_ident the zSeries processor family requires the values shown in Table 1.
Table 1. Auxiliary Vector Types Description
Position | Value | Comments |
e_ident[EI_CLASS] | ELFCLASS64 | For all 64bit implementations |
e_ident[EI_DATA] | ELFDATA64MSB | For all Big-Endian implementations |
The ELF header's e_flags field holds bit flags associated with the file. Since the zSeries processor family defines no flags, this member contains zero.
Processor identification resides in the ELF header's e_machine field and must have the value 22, defined as the name EM_S390.
