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 2009-12-15 20:14:24 +00:00			`// RUN: %clang_cc1 -fsyntax-only %s -verify -pedantic`
add some simple designator testcases. Reject things like this: struct foo Y[10] = { [4] .arr [2] 4 // expected-error {{expected '=' or another designator}} }; because the "missing equals" extension only is valid if there is exactly one array designator. llvm-svn: 58215 2008-10-26 23:22:23 +00:00
