This patch introduces HAVE_NORMAL_FRAME_POINTER Kconfig symbol. When defined, the top level Makefile won't add -fno-omit-frame-pointer cflag (the flag is useless for PowerPC kernels, and also makes gcc generate wrong code).

I am totally confused what you call a frame pointer here. None of the relevant PowerPC ABIs have a frame pointer separate from the stack pointer; the compiler can create one, of course. A better config symbol name and help text would help understand this patch :-) Segher _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@ozlabs.org https://ozlabs.org/mailman/listinfo/linuxppc-dev
