> What happens when you say -fno-inline-functions-called-once? Does it > disable inlining for those functions IN GENERAL, or just for the LARGE It does disable it in general, unless they're marked inline explicitely : The traditional gcc 2.x rules were: I Only inline what is marked inline (but it can decide to not inline) II Also inline others heuristically only with -O3 / -finline-functions [which we don't set in the kernel] Then at some point this additional rule was added: - Also inline everything static that is only called once [on the theory that this shrinks code size which is true according to my measurements] -fno-inline-functions-called once disables this new rule. It's very well and clearly defined. -Andi -- ak@xxxxxxxxxxxxxxx -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
