| * PR10594 cont'd: Use parent die cache for variable lookupJosh Stone2009-09-103-73/+158
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Variable lookup is usually done through the scopes from dwarf_getscopes at a particular pc. This requires an expensive traversal to find the inner-most die containing the pc. For cases where that containing die is known, e.g. at a particular function entry, we can do much better with our die_parent_cache. This may also help get more accurate variable scopes in cases where multiple dies contain a pc and the innermost isn't what we're trying to probe. For example, an inlined call chain of foo->bar->baz may all have the same entry pc, but if the probe was on function("bar"), we would want the variables in bar's scope, not baz's. * dwflpp.h (struct dwflpp): Remove pc_cached_scopes, num_cached_scopes, and cached_scopes, as they are now remembered by the caller. * dwflpp.cxx (dwflpp::getscopes): New - the DIE version uses the parent cache, and the pc version just defers to dwarf_getscopes. (dwflpp::print_locals, literal_stmt_for_local): Take a scopes vector. (dwflpp::find_variable_and_frame_base): Take a scopes vector from the caller instead of computing it every time. (dwflpp::dwarf_getscopes_cached): Removed. * tapsets.cxx (dwarf_var_expanding_visitor::getscopes): New cached lookup function which gets the scopes from the DIE if possible. (dwarf_var_expanding_visitor::visit_target_symbol): Call getscopes.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This avoids repeated DIE traversal by caching all parents on the first call, so future calls are just a simple walk up parent links. * dwflpp.cxx (dwflpp::getscopes_die): New cached function that mimics libdw's dwarf_getscopes_die using cached parent links. (dwflpp::cache_die_parents): New function to build the parent cache. (dwflpp::~dwflpp): Clean up the parent caches. (dwflpp::iterate_over_labels): Use the cached getscopes_die. (dwflpp::find_variable_and_frame_base): Ditto. * tapsets.cxx (dwarf_derived_probe::saveargs): Ditto. (uprobe_derived_probe::saveargs): Ditto.

| * Fix relay_old implementation of fsize_max and fnum_max.Masami Hiramatsu2009-09-091-2/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | With old relayfs, out_fd is used only when non-bulk mode. However, open_oldoutfile and open_relayfs_files open files with fopen and set only percpu_tmpfile. This will cause a problem with -S option, that out_fd will be closed when the file size reaches fsize_max and new fd will be opened only on percpu_tmpfile. So, out_fd should be synchronized with percpu_tmpfile. * runtime/staprun/relay_old.c (open_oldoutfile): Set fd of output file to out_fd[cpu]. (open_relayfs_files): Ditto.

| | | | | | | | | | | | | | | | | | | | | | | | | | | The general approach is to rip out task_finder_tgt's from all over the place (including the unwindsym vmcbs, and the stap_uprobe_specs), and instead have a small handful of them: one for all unwindsyms, and one per abstract probed process (PID or NAME). These are in turn shared by all new stap_unwind_specs by index.
