| | | | | | | optimization. Make sure to require a vtable when trying to get the address of a VTT, otherwise we would never end up emitting the VTT. llvm-svn: 131400
* Add an implementation of thunks for varargs methods. The implementation is ↵Eli Friedman2011-05-061-41/+140
| | | | | | a bit messy, but it is correct as long as the method in question doesn't use indirect gotos. A couple of possible alternative implementations are outlined in FIXME's in this patch. rdar://problem/8077308 . llvm-svn: 130993

* We were emitting construction v-tables with internal linkage all the time.John McCall2011-03-271-2/+6
| | | | | | | | | | | | | | | Emit them instead with the linkage of the VTT. I'm actually really ambivalent about this; it's what GCC does, but outside of improving code size (if the linkage is coalescing), I'm not sure it's at all relevant. Construction vtables are naturally referenced only by the VTT, which is itself only referenced by complete-object constructors and destructors; giving the construction vtables possibly-external linkage is important if you have an optimization that drills through the VTT to a reference to a particular construction vtable which it cannot just emit itself. llvm-svn: 128374

* Use the "undergoes default argument promotion" bit on parameters toJohn McCall2011-03-091-8/+15
| | | | | | | | | | simplify the logic of initializing function parameters so that we don't need both a variable declaration and a type in FunctionArgList. This also means that we need to propagate the CGFunctionInfo down in a lot of places rather than recalculating it from the FAL. There's more we can do to eliminate redundancy here, and I've left FIXMEs behind to do it. llvm-svn: 127314
