| * Turn ctime.stp documentation into proper Tapset Reference markup.Mark Wielaard2009-11-132-12/+25
| | | | | | | | | | * doc/SystemTap_Tapset_Reference/tapsets.tmpl: Add chapter on ctime.stp. * tapset/ctime.stp: Turn documentation into proper reference markup.
| * Accept relative user module paths for -d.Mark Wielaard2009-11-131-5/+13
| | | | | | | | | | | | | | | | | | | | | | | | When using relative (non-canonical) paths for user modules one would get a confusing WARNING: missing unwind/symbol data for module 'bin/test'. Also unless the path started with '/' the task_finder wouldn't start. By checking that the given file can be made absolute (canonicalized) both issues are resolved and the user module will be correctly identified at both translation and runtime. * main.cxx (main): case 'd' try canonicalize_file_name() the argument first to identify user modules.

* PR5916: Exploit kretprobe data storage areaJosh Stone2009-11-105-27/+291
| | | | | | | | | | | | | | | | | | | | Since 2.6.25, kretprobes can carry a data packet to be filled in an entry_handler. This patch lets us store our implicitly-saved $target variables in .return probes in that data area. * tapset/kretprobe.stp: New get/set functions for kretprobe data. * translate.cxx (c_unparser::emit_common_header): Add context->pi_longs. * tapsets.cxx (dwarf_var_expanding_visitor::visit_target_symbol_saved_return): Switch between the old and new methods of saving $vars in .return probes. (dwarf_var_expanding_visitor::gen_mapped_saved_return): The old way. (dwarf_var_expanding_visitor::gen_kretprobe_saved_return): The new way. (dwarf_derived_probe::join_group): Don't register paired entry-handlers. (dwarf_derived_probe::dwarf_derived_probe): Remember saved-var details. (dwarf_derived_probe_group::emit_module_decls): Output saved-var details. Also split the kretprobe handler whether we're on entry or return. (dwarf_derived_probe_group::emit_module_init): Prepare the entry handler. * testsuite/systemtap.base/kretprobe-vars.stp: Test implicit $var saving.
