erichkeane added a comment. I apologize for the lack of detail for this comment, but I didn't seem to capture this at the time. When I investigated this initially, I came up with this solution and it was insufficient. I don't remember WHAT this ends up not fixing however.
When discussing it with @rnk we decided that (according to my notes): "so, addReturnRegisterOutputs needs to look at the LLVM return type, and choose between EAX:EDX for integer / struct return types, ST0 for small FP types, and XMM0/YMM0 etc for vectors/big FP types" The issue is more that the *TargetInfo::addReturnRegisterOutputs doesn't properly configure things, it simply works with integers. It needs to be extended to work with int/struct types, as well as vector/FP types.
