Update tests to use %clang_cc1 instead of 'clang-cc' or 'clang -cc1'. - This is designed to make it obvious that %clang_cc1 is a "test variable" which is substituted. It is '%clang_cc1' instead of '%clang -cc1' because it can be useful to redefine what gets run as 'clang -cc1' (for example, to set a default target). llvm-svn: 91446

Change GetAddressCXXOfBaseClass to use CXXBasePaths for calculating base class offsets. Fix the code to handle virtual bases as well. llvm-svn: 83426
2009-10-07 06:43:30 +08:00
Add a much more thorough test of casts to virtual bases, and fix GetCXXBaseClassOffset to actually pass the test. llvm-svn: 90025
