FUNCTION |

|
|
SYNOPSIS |
|
|
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. |
