Hi, I am working on a new port. I have just compiled libgcc. The target is a 16-bit machine and I realize that libgcc contains functions for SI but not for DI. As the machine is 16-bit and HI instructions are all implemented in the machine descripton, I supposed that libgcc would build SI instructions using HI ones and DI instructions the same way. More over, extend and zero_extend patterns are implemented in all modes. Why are DI instructions not built in libgcc? Is there a solution to get it done? If not, what could/should I do ? Thank you. Regards. Florent
