2016-10-12erts: Refactor find_function_from_pc to return MFALukas Larsson
2016-10-12erts: Refactor out func_info into structLukas Larsson
This commit adds two new structs to be used to represent erlang code in erts. ErtsCodeInfo is used to describe the i_func_info header that is part of all Export entries and the prelude of each function. This replaces all the BeamInstr * that were previously used to point to these locations. After this change the code should never use BeamInstr * with offsets to figure out different parts of the func_info header. ErtsCodeMFA is a struct that is used to descripe a MFA in code. It is used within ErtsCodeInfo and also in Process->current. All function that previously took Eterm * or BeamInstr * to identify a MFA now use the ErtsCodeMFA or ErtsCodeInfo where appropriate. The code has been tested to work when adding a new field to the ErtsCodeInfo struct, but some updates are needed in ops.tab to make it work.
2016-04-15erts: Implement tracer modulesLukas Larsson
Add the possibility to use modules as trace data receivers. The functions in the module have to be nifs as otherwise complex trace probes will be very hard to handle (complex means trace probes for ports for example). This commit changes the way that the ptab->tracer field works from always being an immediate, to now be NIL if no tracer is present or else be the tuple {TracerModule, TracerState} where TracerModule is an atom that is later used to lookup the appropriate tracer callbacks to call and TracerState is just passed to the tracer callback. The default process and port tracers have been rewritten to use the new API. This commit also changes the order which trace messages are delivered to the potential tracer process. Any enif_send done in a tracer module may be delayed indefinitely because of lock order issues. If a message is delayed any other trace message send from that process is also delayed so that order is preserved for each traced entity. This means that for some trace events (i.e. send/receive) the events may come in an unintuitive order (receive before send) to the trace receiver. Timestamps are taken when the trace message is generated so trace messages from differented processes may arrive with the timestamp out of order. Both the erlang:trace and seq_trace:set_system_tracer accept the new tracer module tracers and also the backwards compatible arguments. OTP-10267
