            Bug ID: 20937
           Summary: Detect ODR violations
           Product: libabigail
           Version: unspecified
            Status: NEW
          Severity: enhancement
          Priority: P2
         Component: default
          Assignee: dodji at redhat dot com
          Reporter: dodji at redhat dot com
                CC: libabigail at sourceware dot org
  Target Milestone: ---

It could be possible to make add a --detect-odr-violation option to abidw or to
write a new tool named e.g odrcheck that would do that.

The idea is to modify libabigail to add an ODR-checking mode that:

1/ disables type and decl de-duplication

2/ during type canonicalization, disables the ODR-based optimization which
enables us to avoid comparing two types of the same kind and same name. 
Rather, structurally (memberwise) compare all types during type
canonicalization.

3/ wen comparing class types, does not compare their virtual member functions

3/ during type canonicalization, if two types of the same kind have the same
name but are structurally different flag them as violating ODR.
