+       included in the header.
+
+RETURNS
+       Returns the arch size in bits if known, <<-1>> otherwise.

+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.
