This section describes the Executable and Linking Format (ELF).
For file identification in e_ident the S/390 processor family requires the values shown in Table 1.
Table 1. Auxiliary Vector Types Description
Position | Value | Comments |
e_ident[EI_CLASS] | ELFCLASS32 | For all 32bit implementations |
e_ident[EI_DATA] | ELFDATA32MSB | For all Big-Endian implementations |
The ELF header's e_flags field holds bit flags associated with the file. Since the S/390 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.
