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 -verify -fsyntax-only`
Partial implementation of PR3342: break out pointer sign incompatibilities in assignments from other pointer incompatibilities. Based off of the patch in PR3342. (This doesn't implement -Wno-pointer-sign, but I don't know the driver code very well.) llvm-svn: 67494 2009-03-23 07:59:44 +08:00
