2011-10-06Support for C1x _Atomic specifier (see testcase). This is primarily being ↵Eli Friedman
committed at the moment to help support C++0x <atomic>, but it should be a solid base for implementing the full specification of C1x _Atomic. Thanks to Jeffrey Yasskin for the thorough review! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@141330 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-05Refactor the analysis of C++ cast expressions so that evenJohn McCall

system change in <rdar://problem/10109725> that allows conversion from 'self' in class methods to the root of the class's hierarchy.

2011-09-24Give InitListChecker a verification-only mode, where it neither emits ↵Sebastian Redl
diagnostics nor builds a semantic (structured) initializer list, just reports on whether it can match the given list to the target type. Use this mode for doing init list checking in the initial step of initialization, which will eventually allow us to do overload resolution based on the outcome. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@140457 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-24[microsoft] In Microsoft mode, if we are inside a template class member ↵Francois Pichet
function and we can't resolve an identifier then assume the identifier is type dependent. The goal is to postpone name lookup to instantiation time to be able to search into type dependent base classes. This fixes a few errors when parsing MFC code with clang. BTW clang trunk is now about 5 patches away to be able the parse the default wizard-generated MFC project. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@140452 91177308-0d34-0410-b5e6-96231b3b80d8

2011-09-22In OpenCL, conversions between different vector types are disallowedTobias Grosser
OpenCL 6.2.1 says: "Implicit conversions between built-in vector data types are disallowed." OpenCL 6.2.2 says: "Explicit casts between vector types are not legal." For example: uint4 u = (uint4)(1); int4 i = u; // invalid implicit conversion int4 e = (int4)u; // invalid explicit conversion Fixes PR10967.

2011-09-21In the OpenCL mode, the AltiVec mode must be off and checks must be strictTobias Grosser
OpenCL is different from AltiVec in the way it supports vector literals. OpenCL is strict with regards to semantic checks.

2011-09-10When converting a block pointer to an Objective-C pointer type, extendJohn McCall
the lifetime of the block by copying it to the heap, or else we'll get a dangling reference because the code working with the non-block-typed object will not know it needs to copy. There is some danger here, e.g. with assigning a block literal to an unsafe variable, but, well, it's an unsafe variable. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@139451 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-09Clean up the sentinel-attribute checking code a lot. DocumentJohn McCall
what 'nullPos' is supposed to mean, at least at this one site. Use closed forms for the arithmetic. Rip out some clever but ultimately pointless code that was trying to use 0 or 0L depending the size of a pointer vs. the size of int; first, it didn't work on LLP64 systems, and second, the sentinel checking code requires a pointer-typed value anyway, so this fixit would not have actually removed the warning. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@139361 91177308-0d34-0410-b5e6-96231b3b80d8
