2.3.0.16 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.
