Ah, right. I'm using kdb with it. (And my recollection of when show_stack did have a framepointer version, is that it was hopelessly broken on interrupt frames, and we're much better off without it.) > The only reason to use them would be external debuggers, but those > don't need them on x86-64 neither. Don't need them, but find them as useful on x86_64 as on i386? Certainly, I can go on patching in FRAME_POINTERs for x86_64 as I have done, no problem with that. But it seems both bogus and unhelpful to have that "&& !X86_64" in lib/Kconfig.debug - framepointers are as helpful/useless on x86_64 as the rest.
