           Product: gcc
           Version: 4.8.2

          Priority: P3

Hello.

I'm porting gcc on some architecture which has complex addition, subtraction
and multiplication instructions.

I was trying to define addchi3, subchi3 but it doesn't work.
I've figured out that complex operations are lowered at the tree-level.

Is there any way to support these instructions?

Thanks.
