* Declare and define implicit move constructor and assignment operator.Sebastian Redl2011-08-303-10/+20
| | | | | | | | | This makes the code duplication of implicit special member handling even worse, but the cleanup will have to come later. For now, this works. Follow-up with tests for explicit defaulting and enabling the __has_feature flag to come. llvm-svn: 138821
* The size of struct UnwindException varies by platform with noJohn McCall2011-08-302-3/+31

* Be sure to emit lvalue-to-rvalue casts for loads from x-values.John McCall2011-08-301-24/+18
| | | | | | | Doing this happens to disrupt the pattern that ARC was looking for for move optimizations, so we need to fix that simultaneously. llvm-svn: 138789

* Track whether an AggValueSlot is potentially aliased, and do notJohn McCall2011-08-2510-33/+70
| | | | | | | | | | emit call results into potentially aliased slots. This allows us to properly mark indirect return slots as noalias, at the cost of requiring an extra memcpy when assigning an aggregate call result into a l-value. It also brings us into compliance with the x86-64 ABI. llvm-svn: 138599

* Implement function template specialization at class scope extension in ↵Francois Pichet2011-08-141-0/+1
| | | | | | | | | | | | | | | | | Microsoft mode. A new AST node is introduced: ClassScopeFunctionSpecialization. This node holds a FunctionDecl that is not yet specialized; then during the class template instantiation the ClassScopeFunctionSpecialization will spawn the actual function specialization. Example: template <class T> class A { public: template <class U> void f(U p) { } template <> void f(int p) { } // <== class scope specialization }; This extension is necessary to parse MSVC standard C++ headers, MFC and ATL code. BTW, with this feature in, clang can parse (-fsyntax-only) all the MSVC 2010 standard header files without any error. llvm-svn: 137573
* Move handling of vget_lane/vset_lane before the code that checks the type.Bob Wilson2011-08-131-24/+31
| | | | | | | | | Unlike most of the other Neon intrinsics, these are not overloaded and do not have the extra argument that specifies the vector type. This has not been fatal because the lane number operand is supposed to be an ICE and so that value has harmlessly been used as the type identifier. Radar 9901281. llvm-svn: 137550

* Encapsulate the Objective-C id/Class/SEL "redefinition" types inDouglas Gregor2011-08-111-2/+2
| | | | | | | | | ASTContext with accessors/mutators. The only functional change is that the AST writer won't bother writing the id/Class/SEL redefinition type if it hasn't been explicitly set; previously, it ended up being written as a synonym for the built-in id/Class/SEL. llvm-svn: 137349
* Simplify EH control flow by observing that EH scopes form a simpleJohn McCall2011-08-118-634/+525
| | | | | | | | | | | | | | | hierarchy of delegation, and that EH selector values are meaningful function-wide (good thing, too, or inlining wouldn't work). 2,3d 1a hierarchy of delegation and that EH selector values have the same meaning everywhere in the function instead of being meaningful only in the context of a specific selector. This removes the need for routing edges through EH cleanups, since a cleanup simply always branches to its enclosing scope. llvm-svn: 137293

* Move the creation of the record type for the state of Objective-C fastDouglas Gregor2011-08-093-1/+44
| | | | | | | | enumerations from the ASTContext into CodeGen, so that we don't need to serialize it to AST files. This appears to be the last of the low-hanging fruit for SpecialTypes. llvm-svn: 137124
* Move the construction of the RecordDecl representing the runtimeDouglas Gregor2011-08-092-6/+54
| | | | | | | | layout of a constant NSString from the ASTContext over to CodeGen, since this is solely CodeGen's responsibility. Eliminates one of the unnecessary "special" types that we serialize. llvm-svn: 137121

* Be sure to destroy the normal entry block of a cleanup that weJohn McCall2011-08-061-9/+46
| | | | | | | | | | | | | | | aren't actually going to make a normal cleanup for. Sometimes we optimistically create branches to such blocks for fixups, and then we resolve the fixup to somewhere within the cleanup's scope, and then the cleanup is actually not reachable for some reason. The process of resolving the fixup leaves us with switches whose default edge leads to the cleanup; we can replace that with unreachable, then (in many cases) turn the switch into an unconditional branch.

* Handle "homogeneous aggregates" as required by the ARM AAPCS-VFP ABI.Bob Wilson2011-08-032-48/+154
| | | | | | | | | | | | | A homogeneous aggregate is an aggregate data structure where after flattening any nesting there are 1 to 4 elements of the same base type that is either a float, double, or Neon vector. All Neon vectors of the same size, either 64 or 128 bits, are treated as equivalent for this purpose. When using the AAPCS-VFP ABI, check for homogeneous aggregates and pass them as arguments by expanding them into a sequence of their base types. This requires extending the existing support for expanded arguments to handle not only structs, but also constant arrays and complex types. llvm-svn: 136767
