* Emit complete constructors and destructors as aliases to base constructorsJohn McCall2010-02-173-26/+142
| | | | | | | | and destructors when the two entities are semantically identical, i.e. when the class has no virtual base classes. We only do this for linkage types for which aliases are supported, i.e. internal and external, i.e. not linkonce. llvm-svn: 96451
* Pass through whether a base is virtual or not.Anders Carlsson2010-02-171-17/+26
| | | | llvm-svn: 96449
* implement EmitVAArg. pretty much the same way other targets do.Sanjiv Gupta2010-02-171-1/+21
| | | | llvm-svn: 96446
* Correctly calculate base offsets for 'this' pointer adjustments involving ↵Anders Carlsson2010-02-171-3/+40
| | | | | | virtual bases. This can't be tested yet due to lack of vcall offsets :) llvm-svn: 96441

| | | | | | | | | | | | the offset to the virtual bases statically inside of relying on the virtual base offsets in the object's vtable(s). This is both more efficient and sound against the destructor's manipulation of the vtables. Also extract a few helper routines. Oh and we seem to pass all tests with an optimized clang now. llvm-svn: 96327
