            Bug ID: 24510
           Summary: readelf does not know how to dissect DW_AT_discr_list
           Product: binutils
           Version: unspecified
            Status: NEW
          Severity: normal
          Priority: P2
         Component: binutils
          Assignee: unassigned at sourceware dot org
          Reporter: tromey at sourceware dot org
  Target Milestone: ---

Consider the Ada test case in
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=83935#c2.

Compiling to a .o and then using readelf -wi will yield something
like:

...
 <3><6b>: Abbrev Number: 5 (DW_TAG_variant)
    <6c>   DW_AT_discr_list  : 7 byte block: 1 1 ff ff ff ff 7  (unrecognised)

discr_list has a specified structure, and it would be nice
if readelf could dump it more verbosely.
