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 -emit-llvm -o %t %s`
Add missing RUN line llvm-svn: 55934 2008-09-09 02:01:15 +08:00
In incompatible pointer-typed ?: expressions, add implicit conversion of RHSs to id type instead of void* if either has Objective-C object type. - This ensures the result can still be used in normal places an object can be used, like a message send. Add implicit conversions for ?: applied to qualified id types to ensure that the RHSs are compatible. - This prevents a codegen crash (creating invalid PHI nodes). - Again, this relates to the fact that qualified id types have no canonical types. - Note that the implicit type casted to is incorrect, however this doesn't currently cause problems because of the flexibility of the id type. Test cases for above. llvm-svn: 55346 2008-08-26 08:41:39 +08:00			`@protocol P0`
