(stap_find_vma_map_info): Likewise. (stap_find_vma_map_info_user): New function. (stap_drop_vma_maps): New function. * runtime/sym.h (addr): Renamed to static_addr, to store addresses for sections which are always mapped at the same address. (_stp_module_relocate): Add extra struct task_struct *tsk argument. * runtime/sym.c (_stp_tf_exec_cb): New callback, calls stap_drop_vma_maps. (_stp_tf_mmap_cb): Don't store address in module.section, but call stap_add_vma_map_info() per tsk->group_leader for matched module. Don't register empty/null modules. (_stp_module_relocate): Take extra struct task_struct *tsk argument, cache last tsk used. Only use section->static_addr for none dynamic modules. Use stap_find_vma_map_info_user() to locate dynamic modules. (_stp_mod_sec_lookup): Add extra argument unsigned long *rel_addr to optionally store relative address when module/section found. (_stp_kallsyms_lookup): Use _stp_mod_sec_lookup to find relative address. (_stp_sym_init): Register _stp_tf_exec_cb in stap_task_finder_target. Add error check to see if task finder could be initialized. * dwflpp.cxx (emit_address): Pass NULL for kernel/modules and current for user tasks to _stp_module_relocate. * runtime/transport/symbols.c (_stp_do_relocation): Set new static_addr _stp_section field. * runtime/unwind.c (adjustStartLoc): Take new struct task_struct *tsk argument and pass to stap_find_vma_map_info_user and _stp_module_relocate to find adjusted addr. (_stp_search_unwind_hdr): Pass through struct task_struct *tsk. (unwind_frame): Likewise. * tapset/context-symbols.stp (probemod): Add NULL to _stp_mod_sec_lookup call to indicate we aren't interested in relative address. * tapsets.cxx (dwarf_derived_probe_group::emit_module_init): Pass NULL to _stp_module_relocate to indicate kernel/module address.
