(Various problems have no work around y= et to avoid them.) This turned out to be a consequence of the other problems. It was easier to discover once I induced gcc 4.2.1 to generate some example code with r31 in use as a frame pointer. (I used alloca.) Observing its behavior and the .eh_frame output indicated I'd misinterpreted where the earliest problem was. --=20 You are receiving this mail because: You are the assignee for the bug.=
