It does already for static functions in 5.x (with -fipa-ra). And with LTO it can be used even somewhat globally. Even older version supported it, for only for x86->SSE on 32bit, which is useless for the kernel. But the new IPA-RA propagates which registers are clobbered. That said it will probably be a long time until we can drop support for older compilers. So for now the manual method is still needed. -Andi -- To unsubscribe from this list: send the line "unsubscribe live-patching" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
