FUNCTION
bfd_canonicalize_reloc
SYNOPSIS
long bfd_canonicalize_reloc
(bfd *abfd, asection *sec, arelent **loc, asymbol **syms);
DESCRIPTION
Call the back end associated with the open BFD
@var{abfd} and translate the external form of the relocation
information attached to @var{sec} into the internal canonical
form. Place the table into memory at @var{loc}, which has
been preallocated, usually by a call to
<<bfd_get_reloc_upper_bound>>. Returns the number of relocs, or
-1 on error.
The @var{syms} table is also needed for horrible internal magic
reasons.
