| | | | | | | | | | | | | | | | | | | | PR 2341 (partial fix) * elaborate.h (struct derived_probe): Added needs_global_locks() member function. Unless overridden, will return true indicating that this probe needs locks around global variable references. * tapsets.cxx (struct be_derived_probe): Added override of default needs_global_locks() returning false. begin/end probes don't need locks around global variables, since they aren't run concurrently with any other probes. * translate.cxx (c_unparser::emit_common_header): Updated probe_contents logic to match the logic in emit_probe. (c_unparser::emit_probe): Added whether the probe needs global variable locks to the probe string (that helps eliminate duplicate probes). The generated C changes based on whether or not global variable locks are needed, but the pass 2 output doesn't differ between a probe that needs global variable locks and one that doesn't. If the probe doesn't need global variable locks, doesn't output them.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * translate.cxx: Added inclusion of session.h. (translate_pass): Instead of asking each probe to emit itself, we ask the session's probes member variable to emit all the probes. * tapsets.cxx: Added inclusion of session.h. Added a register_probe member function to all derived_probe based classes. Added a derived_probe_group derived class for all probe types: (be_derived_probe_group): New class. (never_derived_probe_group): New class. (dwarf_derived_probe_group): New class. (timer_derived_probe_group): New class. (profile_derived_probe_group): New class. (mark_derived_probe_group): New class. (hrtimer_derived_probe_group): New class (derived_probe_group_container): New class. * elaborate.h: Removed inclusion of session.h since session.h now includes elaborate.h. (derived_probe): Added register_probe member function. (derived_probe_group): Added class definition. This is the base class of all of the derived probe groups - dwarf, timer, etc. (derived_probe_group_container): Added class definition. An instance of this class will be stored in the session and contain all the other probe groups. * elaborate.cxx (derived_probe_group::register_probe): Added derived_probe_group::register_probe stubs. (alias_derived_probe::register_probe): Added register_probe member function. (semantic_pass_symbols): After deriving a probe, the probes now register themselves with the session. * session.h: Includes elaborate.h to get derived_probe_group_container definition. systemtap_session class 'probes' member variable switched from a vector of derived probes to a derived_probe_group_container. * buildrun.cxx: Added inclusion of session.h since it was removed from elaborate.h. * main.cxx: Added inclusion of session.h since it was removed from elaborate.h. * parse.h: Added forward struct declarations. * staptree.h: Removed inclusion of session.h.

| | | | | | | | | | | | * elaborate.cxx (duplicate_function_remover): Added class. (get_functionsig): Added function. (semantic_pass_opt5): New function merges duplicate identical functions into one function. (semantic_pass_optimize): Calls semantic_pass_opt5. * translate.cxx (c_unparser::emit_probe): Changed to merge duplicate probes bodies by making the duplicate probe just call the original probe (BZ# 2421).
