We call these tests in the second test function where they are x-failed on Windows. I forgot to remove the tests from the first test function (which is not x-failed on Windows) when extracting these calls into their own test function, so the test is still failing on Windows. llvm-svn: 375271

Test calling an overriden method.
|
|
|
|
Note:
|
|
This verifies that LLDB is correctly building the method overrides table.
|
|
If this table is not built correctly then calls to overridden methods in
|
|
derived classes may generate references to non-existant vtable entries,
|
|
as the compiler treats the overridden method as a totally new virtual
|
|
method definition.
