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 2009-12-16 04:14:24 +08:00			`// RUN: %clang_cc1 %s -emit-llvm-only -verify`
Make sure isCopyAssignment is only true for actual copy assignment operators, instead of all assignment operators. The mistake messes up IRGen because it ends up assuming that the assignment operator is actually the implicit copy assignment operator, and therefore tries to emit the RHS as an lvalue. llvm-svn: 86307 2009-11-07 08:02:45 +08:00
