+/* 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=Linux, 1=Hurd, 2=Solaris, ...) and the remaining three
|
|
|
+ identify the earliest release of that OS that supports this ABI.
|
|
|
+ See abi-tags (top level) for details. */
