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. + * + * The extensibility scheme for the SIDE ABI is as follows: + * + * * Existing field types are never changed nor extended. Field types + * can be added to the ABI by reserving a label within + * enum side_type_label. + * * Existing attribute types are never changed nor extended. Attribute + * types can be added to the ABI by reserving a label within + * enum side_attr_type. + * * Each union part of the ABI has an explicit side defined by a + * side_padding() member. Each structure and union have a static + * assert validating its size. + * + * Handling of unknown types by the tracers: + * + * * A tracer may choose to support only a subset of the types supported + * by libside. When encountering an unknown or unsupported type, the + * tracer has the option to either disallow the entire event or skip + * over the unknown type, both at event registration and when + * receiving the side_call arguments. + * + * * Event descriptions can be extended by adding fields at the end of + * the structure. The "struct side_event_description" and "struct + * side_event_state" are therefore structures with flexible size and + * must not be used within arrays. + */ -//TODO: as those structures will be ABI,
