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 -verify -fsyntax-only -std=c90 %s`
			`// RUN: %clang_cc1 -verify -fsyntax-only -std=c99 %s`
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`
Fix isIntegerConstantExpr eval of __builtin_offsetof to return result with correct width. - PR2728. Also, fix PR2727 test case. llvm-svn: 55493 2008-08-29 02:42:20 +08:00
