Hi Jon, > From: Hunter, Jon > Sent: Wednesday, May 13, 2009 10:48 AM > KBUILD_CFLAGS += -fno-omit-frame-pointer -fno-optimize-sibling-calls Ok so -fno-optimize-sibling-calls is busted in older compiler. I wonder if there are other reasons for the exclusion of this optimization in kernel code. Would be interesting to google and see. There might be 3 other reasons it is needed in addition to one we tripped over.
