-FUNCTION
- bfd_preserve_save
-
-SYNOPSIS
- bfd_boolean bfd_preserve_save (bfd *, struct bfd_preserve *);
-
-DESCRIPTION
- When testing an object for compatibility with a particular
- target back-end, the back-end object_p function needs to set
- up certain fields in the bfd on successfully recognizing the
- object. This typically happens in a piecemeal fashion, with
- failures possible at many points. On failure, the bfd is
- supposed to be restored to its initial state, which is
- virtually impossible. However, restoring a subset of the bfd
- state works in practice. This function stores the subset and
- reinitializes the bfd.
