operator new[]. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@111788 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-22Go back to asking CodeGenTypes whether a type is zero-initializable.John McCall
Make CGT defer to the ABI on all member pointer types. This requires giving CGT a handle to the ABI. It's way easier to make that work if we avoid lazily creating the ABI. Make it so. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@111786 91177308-0d34-0410-b5e6-96231b3b80d8

2010-08-22When performing value-initialization for a class with a non-trivial,Douglas Gregor
implicitly-defined default constructor, zero-initialize the memory before calling the default constructor. Previously, we would only zero-initialize in the case of a trivial default constructor. Also, simplify the hideous logic that determines when we have a trivial default constructor and, therefore, don't need to emit any call at all. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@111779 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-22Clean up a very silly use of first-class aggregates.John McCall
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@111777 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-22Experiment with using first-class aggregates to represent member functionJohn McCall
pointers. I find the resulting code to be substantially cleaner, and it makes it very easy to use the same APIs for data member pointers (which I have conscientiously avoided here), and it avoids a plethora of potential inefficiencies due to excessive memory copying, but we'll have to see if it actually works. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@111776 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-22Extract member function pointer comparison and null comparison intoJohn McCall
the ABI code. Implement correct semantics for these on ARM. I believe this completes the implementation of member function pointers on ARM. I think I'm going to switch member function pointers over to be non-aggregates while I have all this in mind. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@111774 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-22Abstract out member-pointer creation. I'm really unhappy about the currentJohn McCall
duplication between the constant and non-constant paths in all of this. Implement ARM ABI semantics for member pointer constants and conversion. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@111772 91177308-0d34-0410-b5e6-96231b3b80d8

2010-08-22Abstract out member-pointer conversions.John McCall

2010-08-21The ARM C++ ABI is sufficiently different from the Itanium C++ ABI thatJohn McCall
it deserves its own enumerator. Obviously the implementations should closely follow the Itanium ABI except in cases of divergence. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@111749 91177308-0d34-0410-b5e6-96231b3b80d8

2010-08-21IRgen: Switch more MakeAddr() users to MakeAddrLValue; this time for calls ↵Daniel Dunbar
which were previously not computing the qualifier list. In most cases, I don't think it matters, but I believe this is conservatively more correct / consistent. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@111717 91177308-0d34-0410-b5e6-96231b3b80d8

2010-08-19Add some enum goodness as requested by Chris. Now instead of storing theCharles Davis
active C++ ABI as a raw string, we store it as an enum. This should improve performance somewhat. And yes, this time, I started from a clean build directory, and all the tests passed. :) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@111507 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-18Generate Attr subclasses with TableGen.Sean Hunt
Now all classes derived from Attr are generated from TableGen. Additionally, Attr* is no longer its own linked list; SmallVectors or Attr* are used. The accompanying LLVM commit contains the updates to TableGen necessary for this. Some other notes about newly-generated attribute classes: - The constructor arguments are a SourceLocation and a Context&, followed by the attributes arguments in the order that they were defined in Attr.td - Every argument in Attr.td has an appropriate accessor named getFoo, and there are sometimes a few extra ones (such as to get the length of a variadic argument). Additionally, specific_attr_iterator has been introduced, which will iterate over an AttrVec, but only over attributes of a certain type. It can be accessed through either Decl::specific_attr_begin/end or the global functions of the same name. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@111455 91177308-0d34-0410-b5e6-96231b3b80d8
