2012-08-21[asan] If we are compiling with ASan, add metadata indicating dynamically ↵Kostya Serebryany
initialized globals. Patch by Reid Watson, reviewed by Richard Smith git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@162259 91177308-0d34-0410-b5e6-96231b3b80d8
2012-08-21When performing a trivial copy of a C++ type, we must be careful notJohn McCall
to overwrite objects that might have been allocated into the type's tail padding. This patch is missing some potential optimizations where the destination is provably a complete object, but it's necessary for correctness. Patch by Jonathan Sauer. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@162254 91177308-0d34-0410-b5e6-96231b3b80d8
2012-08-21Screw around with ObjCRuntime some more, changing theJohn McCall
diagnostics for bad deployment targets and adding a few more predicates. Includes a patch by Jonathan Schleifer to enable ARC for ObjFW. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@162252 91177308-0d34-0410-b5e6-96231b3b80d8
2012-08-20Fix a pair of bugs relating to properties in ARC.John McCall
First, when synthesizing an explicitly strong/retain/copy property of Class type, don't pretend during compatibility checking that the property is actually assign. Instead, resolve incompatibilities by secretly changing the type of *implicitly* __unsafe_unretained Class ivars to be strong. This is moderately evil but better than what we were doing. Second, when synthesizing the setter for a strong property of non-retainable type, be sure to use objc_setProperty. This is possible when the property is decorated with the NSObject attribute. This is an ugly, ugly corner of the language, and we probably ought to deprecate it. The first is rdar://problem/12039404; the second was noticed by inspection while fixing the first. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@162244 91177308-0d34-0410-b5e6-96231b3b80d8

2012-08-14Avoid using i64 types for vld1q_lane/vst1q_lane intrinsics.Bob Wilson
The backend has to legalize i64 types by splitting them into two 32-bit pieces, which leads to poor quality code. If we produce code for these intrinsics that uses one-element vector types, which can live in Neon vector registers without getting split up, then the generated code is much better.

attribute. It is a variation of the x86_64 ABI: * A struct returned indirectly uses the first register argument to pass the pointer. * Floats, Doubles and structs containing only one of them are not passed in registers. * Other structs are split into registers if they fit on the remaining ones. Otherwise they are passed in memory. * When a struct doesn't fit it still consumes the registers. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@161022 91177308-0d34-0410-b5e6-96231b3b80d8
