3.8 Directive OPTION ELF

3.8 Directive OPTION ELF

Directive OPTION ELF allows to fine-tune the values written to the ELF header if output format ELF (see -elf or -elf64) is selected. For other output formats, this option has no effect. The syntax for the directive is:

OPTION ELF:osabi

The only argument <osabi> will be copied to the ELF header field EI_OSABI. It's a numeric constant, and according to the elf specs some valid values are:

0 ELFOSABI_NONE unspecified 1 ELFOSABI_HPUX HP-UX 2 ELFOSABI_NETBSD NetBSD 3 ELFOSABI_LINUX Linux, default 6 ELFOSABI_SOLARIS Sun Solaris 7 ELFOSABI_AIX IBM AIX 9 ELFOSABI_FREEBSD FreeBSD 12 ELFOSABI_OPENBSD OpenBSD
