Why disable caller-save regardless of profile_flag; is there some long-standing bug in caller-save for "old" targets? I guess you want: > + if (profile_flag && (!HAVE_prologue || !HAVE_epilogue)) Not that it matter too much, I don't think we care about such targets. I don't even bother to grep if there is any. :) brgds, H-P
