When specified, this event property will generate an extra set of functions that provide the ability to inject trace points into TCG-generated code. Note that the regular backend-dependant functions will also be generated. The extra files generated, and their functions are: - trace-helper.h Declares a 'trace_proxy_##name' TCG helper for each affected trace event. - trace-helper.c Defines a 'trace_proxy_##name' TCG helper for each affected trace event, which simply calls 'trace_##name'. Note that this scheme neatly blends with the "instrument" property. - trace-gen.h Defines a 'trace_gen_##name##_backend' function for each affected trace event, which handles all the (de)allocation of TCG temporaries and calls 'gen_helper_trace_proxy_##name'. If the "instrument" property is not present, 'trace_gen_##name' is defined as an alias. This file is instended to be included instead of "trace.h" for generating TCG calls to trace points. In order to fully exploit the information available during TCG code generation, trace events with the "gen" property can also use TCG data types (e.g., TCG_ptr), which are gracefully handled by 'tracetool' when generating the "trace.h" and "trace.c" files.
