/* Define an ELF note identifying the operating-system ABI that the
|
|
executable was created for. The ELF note information identifies a
|
|
particular OS or coordinated development effort within which the
|
|
ELF header's e_machine value plus (for dynamically linked programs)
|
|
the PT_INTERP dynamic linker name and DT_NEEDED shared library
|
|
names fully identify the runtime environment required by an
|
|
executable.
|
|
|
|
The general format of ELF notes is as follows.
|
|
Offsets and lengths are bytes or (parenthetical references) to the
|
|
values in other fields.
|
|
|
|
offset length contents
|
|
0 4 length of name
|
|
4 4 length of data
|
|
8 4 note type
|
|
12 (0) vendor name
|
|
- null-terminated ASCII string, padded to 4-byte alignment
|
|
12+(0) (4) note data,
|
|
|
|
The GNU project and cooperating development efforts (including the
|
|
Linux community) use note type 1 and a vendor name string of "GNU"
|
|
for a note descriptor that indicates ABI requirements. The note data
|
|
is four 32-bit words. The first of these is an operating system
|
|
number (0=Hurd, 1=Linux, 2=Solaris, ...) and the remaining three
|
|
identify the earliest release of that OS that supports this ABI.
|
|
See abi-tags (top level) for details. */
