Law 2011-12-05 18:53:34 UTC --- Other ports seem to work OK when the requirement for a frame pointer is conditional on the size of the stack. It's not the most common case, but it does come up in several ports. I still haven't seen a good description of why the particular insn needs reloads. Not everyone is familiar with the guts of the avr port. I'd then be looking at init_caller_save to determine why it thinks a particular address is OK for a caller-save, when in fact it isn't OK. jeff
