2012-02-24Implement a new type trait __is_trivially_constructible(T, Args...)Douglas Gregor
that provides the behavior of the C++11 library trait std::is_trivially_constructible<T, Args...>, which can't be implemented purely as a library. Since __is_trivially_constructible can have zero or more arguments, I needed to add Yet Another Type Trait Expression Class, this one handling arbitrary arguments. The next step will be to migrate UnaryTypeTrait and BinaryTypeTrait over to this new, more general TypeTrait class.

2012-02-23Update parser's disambiguation to cope with braced function-style casts inRichard Smith
C++11, and with braced-init-list initializers in conditions. This exposed an ambiguity with enum underlying types versus bitfields, which we resolve by treating 'enum E : T {' as always defining an enumeration (even if it would only successfully parse as a bitfield). This appears to be g++ compatible. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@151227 91177308-0d34-0410-b5e6-96231b3b80d8

2012-02-23[analyzer] Invalidate the region passed to pthread_setspecific() call.Anna Zaks
Make this call an exception in ExprEngine::invalidateArguments: 'int pthread_setspecific(ptheread_key k, const void *)' stores a value into thread local storage. The value can later be retrieved with 'void *ptheread_getspecific(pthread_key)'. So even thought the parameter is 'const void *', the region escapes through the call. (Here we just blacklist the call in the ExprEngine's default logic. Another option would be to add a checker which evaluates the call and triggers the call to invalidate regions.) Teach the Malloc Checker, which treats all system calls as safe about the API. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@151220 91177308-0d34-0410-b5e6-96231b3b80d8
