-/* ELF core files contain a segment of type PT_NOTE, that holds much of
- the information that would normally be available from the /proc interface
- for the process, at the time the process dumped core. Currently this
- includes copies of the prstatus, prpsinfo, and fpregset structures.
-
- Since these structures are potentially machine dependent in size and
- ordering, bfd provides two levels of support for them. The first level,
- available on all machines since it does not require that the host
- have /proc support or the relevant include files, is to create a bfd
- section for each of the prstatus, prpsinfo, and fpregset structures,
- without any interpretation of their contents. With just this support,
- the bfd client will have to interpret the structures itself. Even with
- /proc support, it might want these full structures for it's own reasons.
-
- In the second level of support, where HAVE_SYS_PROCFS_H is defined,
- bfd will pick apart the structures to gather some additional
- information that clients may want, such as the general register
- set, the name of the exec'ed file and its arguments, the signal (if
- any) that caused the core dump, etc.
