            Bug ID: 30084
           Summary: readelf.c:handle_bit_registers() sets parameter desc
                    without using it.
           Product: elfutils
           Version: unspecified
            Status: NEW
          Severity: normal
          Priority: P2
         Component: general
          Assignee: unassigned at sourceware dot org
          Reporter: dje at sourceware dot org
                CC: elfutils-devel at sourceware dot org
  Target Milestone: ---

static unsigned int
handle_bit_registers (const Ebl_Register_Location *regloc, const void *desc,
unsigned int colno)
{
  desc += regloc->offset;
...

The local parameter desc is updated but not used.  The function explicitly
calls abort(), so the implementation is not complete and not intended to be
used.  The function should add

(void) desc;

or something to create an artificial use and avoid a spurious warning.
