+FUNCTION

+
+SYNOPSIS
+ int bfd_get_sign_extend_vma (bfd *abfd);
+
+DESCRIPTION
+ Indicates if the target architecture "naturally" sign extends
+ an address. Some architectures implicitly sign extend address
+ values when they are converted to types larger than the size
+ of an address. For instance, bfd_get_start_address() will
+ return an address sign extended to fill a bfd_vma when this is
+ the case.
+
+RETURNS
+ Returns <<1>> if the target architecture is known to sign
+ extend addresses, <<0>> if the target architecture is known to
+ not sign extend addresses, and <<-1>> otherwise.
