New Revision: 96974

URL: http://llvm.org/viewvc/llvm-project?rev=96974&view=rev
Log:
Do not rely on write_symbols to disable debug info for super class added as an invisible member of derived class. write_symbols controls debug_hooks which are used to emit debug info in various formats in gcc. llvm-gcc does not use this debug_hooks interface to emit debugging information.

Test case is at llvm/test/FrontendObjC/2010-02-23-DbgInheritance.m
