2010-08-23Support for IRGen of synthesize bitfield ivars inFariborz Jahanian
objc-nonfragile-abi2 (radar 7824380). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@111823 91177308-0d34-0410-b5e6-96231b3b80d8

2010-08-23fix rdar://8340348, a miscompile of boost that was exposed by r109848.Chris Lattner
That revision started classifying truly empty structs like "Y" and "X" as being NoClass/NoClass and turning them into 'ignore'. The call code turns around and allocates space for the ignored argument with GetUndefRValue. The bug is that GetUndefRValue would return the address as undef, instead of returning an object with a defined address but undefined contents. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@111794 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-23Abstract out everything having to do with member pointers into the ABIJohn McCall
class; they should just be completely opaque throughout IR gen now, although I haven't really audited that. Fix a bug apparently inherited from gcc-4.2 where we failed to null-check member data pointers when performing derived-to-base or base-to-derived conversions on them. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@111789 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
Pretty much everything having to do with member pointers is ABI-specific. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@111770 91177308-0d34-0410-b5e6-96231b3b80d8

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

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
