[PATCH] Support new 'h' core note item format for hidden fields

Signed-off-by: Petr Machata <>

 The use case here is NT_ARM_HW_BREAK and NT_ARM_HW_WATCH core notes.
 These end in a 4-byte padding field.  If that field is absent from the
 note description, readelf notices that we still have data left, and
 does another pass through the items.  But we don't want to really show
 that field either, as it carries no useful information.  Hence this.

 I initially chose '\0' for that field, but handle_auxv_note uses that
 for fields that should be hidden if all zero, but displayed otherwise.
 That might be eventually useful for core note items as well.

 OK for master?
