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 -fsyntax-only %s -verify`
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`

Wire up '-Wignored-qualifiers' to the warning on 'const' in 'const int f()'. This flag and warning match GCC semantics. Also, move it to -Wextra as this is a largely cosmetic issue and doesn't seem to mask problems. Subsequent fixes to the tests which no longer by default emit the warning. Added explicit test cases for both C and C++ behavior with the warning turned on. llvm-svn: 108325 2010-07-14 14:36:18 +08:00			`struct S const foo(void);`
When forming a function call or message send expression, be sure to strip cv-qualifiers from the expression's type when the language calls for it: in C, that's all the time, while C++ only does it for non-class types. Centralized the computation of the call expression type in QualType::getCallResultType() and some helper functions in other nodes (FunctionDecl, ObjCMethodDecl, FunctionType), and updated all relevant callers of getResultType() to getCallResultType(). Fixes PR7598 and PR7463, along with a bunch of getResultType() call sites that weren't stripping references off the result type (nothing stripped cv-qualifiers properly before this change). llvm-svn: 108234 2010-07-13 16:18:22 +08:00
