Subject: frame pointer must be single register?
Date: Fri, 08 Jul 2011 17:07:00 -0000 [thread overview]
Message-ID: <201107081707.p68H7aGe003027@greed.delorie.com> (raw)
Is there an unwritten rule that the frame pointer must be a single
hard register? I'm working on a port where $fp is a register pair,
and I've seen gcc allocate the second register to other things
(causing all sorts of problems).
