2010-08-31Teach IR generation to return 'this' from constructors and destructorsJohn McCall
under the ARM ABI. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@112588 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-25GCC didn't care for my attempt at API compatibility, so brute-force everythingJohn McCall
to the new constants. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@112047 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-23chandlerc pointed out that ending a line with /\ is not very friendly. :)John McCall
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@111797 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
2010-08-22Clean 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 more member-pointerness out.John McCall
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@111771 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
2010-08-22Implement the call parts of the member-function-pointer ARM C++ ABI.John McCall
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@111766 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-22Extract calls to method pointers out as an ABI routine.John McCall
No functionality change. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@111752 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
2010-08-16Implement support for member pointers under the Microsoft C++ ABI in theCharles Davis
AST library. This also adds infrastructure for supporting multiple C++ ABIs in the AST. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@111117 91177308-0d34-0410-b5e6-96231b3b80d8
2010-05-25IRgen: Add a stub class for generating ABI-specific C++ code.Charles Davis
This class only supports name mangling (which is apparently used during C/ObjC codegen). For now only the Itanium C++ ABI is supported. Patches to add a second C++ ABI are forthcoming. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@104630 91177308-0d34-0410-b5e6-96231b3b80d8
