This message involves a technical question regarding gcc machine
definitions.

I have a machine which generally allows both absolute and indirect addressing
(via registers) of memory. Thus, I generally use the 'm' mode in insn
definitions. I have one instruction, however, which allows only
indirect addressing -- no absolute addressing allowed. How can I specify
this in the machine definition?

thanks.
