Problem summary

• ****************************************************************
  * USERS AFFECTED: 1. Users who need to provide the location of *
  *                 the customization file.                      *
  *                 2. Users of foreign exception.               *
  *                 3. Users with private constants and relying  *
  *                 on rent support.                             *
  *                 4. Users with operator== for an enum         *
  *                 parameter with a bool enum base and no       *
  *                 enumerator list                              *
  ****************************************************************
  * PROBLEM DESCRIPTION: 1. Prior to this fix there was no       *
  *                      mechanism for this.                     *
  *                      2. The current exception handling       *
  *                      mechanism does not handle foreign       *
  *                      exceptions                              *
  *                      3. Private constants are treated as     *
  *                      rent                                    *
  *                      4. The compiler crashes when parsing    *
  *                      operator== for an enum parameter with   *
  *                      a bool enum base and no enumerator      *
  *                      list. For example:                      *
  *                      enum Foo : bool;                        *
  *                      bool bar(Foo a, Foo b) {    return a == *
  *                       b; }                                   *
  ****************************************************************
  * RECOMMENDATION: Install the PTF                              *
  ****************************************************************
  1. The customization file is not needed when the system
  installation uses the default settings. However if that is not
  the case, this fix will provide a way to provide customization
  file .
  2.  The current exception handling mechanism catches a foreign
  exception (e.g., from objects generated by other compilers)
  with the catch (...) clause and then tries to delete the
  foreign exception object which leads to System Completion
  Code=0C4).
  3. Private constants should not be treated as rent
  4.  The operator== for an enum parameter with a bool enum base
  and no enumerator list should be accepted by compiler.
  

Problem conclusion

• 1. The CLANG_CONFIG_PATH environment variable was created which
  can be set to location of 'clang.cfg' the customization file
  for the compiler to use instead of the default one.
  2. This fix modifies the personality routine so foreign
  exceptions result with no handler and calling the terminate
  function from the foreign runtime.
  3. Private constants are not marked as rent
  4. The compiler accepts operator== in case stated above.
