Update all tests other than Driver/std.cpp to use -std=c++11 rather than -std=c++0x. Patch by Ahmed Charles! llvm-svn: 141900 2011-10-14 06:29:44 +08:00			`// RUN: %clang_cc1 -fsyntax-only -verify %s -std=c++11`
Add support for GCC's '__auto_type' extension, per the GCC manual: https://gcc.gnu.org/onlinedocs/gcc/Typeof.html Differences from the GCC extension: * __auto_type is also permitted in C++ (but only in places where it could appear in C), allowing its use in headers that might be shared across C and C++, or used from C++98 * __auto_type can be combined with a declarator, as with C++ auto (for instance, "__auto_type p") multiple variables can be declared in a single __auto_type declaration, with the C++ semantics (the deduced type must be the same in each case) This patch also adds a missing restriction on applying typeof to a bit-field, which GCC has historically rejected in C (due to lack of clarity as to whether the operand should be promoted). The same restriction also applies to __auto_type in C (in both GCC and Clang). This also fixes PR25449. Patch by Nicholas Allegra! llvm-svn: 252690 2015-11-11 10:02:15 +08:00			`// RUN: %clang_cc1 -fsyntax-only -verify %s -std=c++1y`
Implement enough of the 'auto' keyword so we can claim to support N2546. llvm-svn: 74307 2009-06-27 02:41:36 +08:00			`void f() {`
Switch diagnostic text from "C++0x" over to "C++11". We'd also like for "C++11" or "c++11" to be used for the warning groups, but without removing the old warning flags. Patches welcome; I've run out of time to work on this today. llvm-svn: 141801 2011-10-13 03:26:40 +08:00			`auto int a; // expected-warning {{'auto' storage class specifier is not permitted in C++11, and will not be supported in future releases}}`
