This type system requires that every type is - * statically or dynamically declared and then registered, thus giving - * tracers a complete description of the events and their associated - * fields before the associated instrumentation is invoked. The - * application needs to copy each argument (side_arg_...()) onto the - * stack when calling the instrumentation. - * - * This is the most expressive of the 3 type systems, althrough not the - * fastest due to the extra copy of the arguments. - * - * * Data-gathering type system: This type system requires every type to - * be statically or dynamically declared and registered, but does not - * require the application to copy its arguments onto the stack. - * Instead, the type description contains all the required information - * to fetch the data from the application memory. The only argument - * required from the instrumentation is the base pointer from which - * the data should be fetched. - * - * This type system can be used as an event field, or nested within - * the stack-copy type system. Nesting of gather-vla within - * gather-array and gather-vla types is not allowed. - * - * This type system is has the least overhead of the 3 type systems. - * - * * Dynamic type system: This type system receives both type - * description and actual data onto the stack at runtime. It has more - * overhead that the 2 other type systems, but does not require a - * prior registration of event field description. This makes it useful - * for seldom used types which are not performance critical, but for - * which registering each individual events would needlessly grow the - * number of events to declare and register. - * - * Another use-case for this type system is for use by dynamically - * typed language runtimes, where the field type is only known when - * the instrumentation is called. - * - * Those dynamic types can be either used as arguments to a variadic - * field list, or as on-stack instrumentation argument for a static - * type SIDE_TYPE_DYNAMIC place holder in the stack-copy type system. + * * If the semantic of the "struct side_event_state_N" fields change, + * the SIDE_EVENT_STATE_ABI_VERSION should be increased.
