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 -E -std=c++11 %s -o - | FileCheck --check-prefix=CHECK-0X %s
tests: Use %clangxx when using driver for C++, in case C++ support is disabled. llvm-svn: 107153

Add a bunch more feature-checking macros for C++0x features. Some of these are disabled with the intent that users can start with them now and not have to change a thing to have them work when we implement the features. llvm-svn: 93312

Some improvements to the handling of C11 atomic types: - Add atomic-to/from-nonatomic cast types - Emit atomic operations for arithmetic on atomic types - Emit non-atomic stores for initialisation of atomic types, but atomic stores and loads for every other store / load - Add a __atomic_init() intrinsic which does a non-atomic store to an _Atomic() type. This is needed for the corresponding C11 stdatomic.h function. - Enables the relevant __has_feature() checks. The feature isn't 100% complete yet, but it's done enough that we want people testing it. Still to do: - Make the arithmetic operations on atomic types (e.g. Atomic(int) foo = 1; foo++;) use the correct LLVM intrinsic if one exists, not a loop with a cmpxchg. - Add a signal fence builtin - Properly set the fenv state in atomic operations on floating point values - Correctly handle things like _Atomic(_Complex double) which are too large for an atomic cmpxchg on some platforms (this requires working out what 'correctly' means in this context) - Fix the many remaining corner cases llvm-svn: 148242

Clean up the C++0x __has_feature tests.

Audit and finish the implementation of C++0x nullptr, fixing two minor issues along the way: - Non-type template parameters of type 'std::nullptr_t' were not permitted. - We didn't properly introduce built-in operators for nullptr ==, !=, <, <=, >=, or > as candidate functions . To my knowledge, there's only one (minor but annoying) part of nullptr that hasn't been implemented: catching a thrown 'nullptr' as a pointer or pointer-to-member, per C++0x [except.handle]p4. llvm-svn: 131813
