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`
Prior to adding the new "expected-no-diagnostics" directive to VerifyDiagnosticConsumer, make the necessary adjustment to 580 test-cases which will henceforth require this new directive. llvm-svn: 166280 2012-10-19 20:44:48 +08:00			`// expected-no-diagnostics`
PR5462: Don't run off the edge of the argument array for vararg handling when there are more parameters in the prototype than arguments to the call. llvm-svn: 88759 2009-11-14 12:43:10 +08:00			`// PR5462`
