	* config/sparc/sparc.md: Window save takes a single integer


This will probably break in 64-bit mode, the operand can be a DImode register.

You are right, I forgot about that. Is there a mode one can use thatchanges depending on the target architecture (32-bit on 32-bitarchitectures and 64-bit on 64-bit architectures)? Or does one have toadd a 32-bit and a 64-bit variant of window_save?
