* PR5916: Exploit kretprobe data storage areaJosh Stone2009-11-102-0/+74
| | | | | | | | | | | | | | | | | | | | 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.

* Use less idle time in testsuite.Mark Wielaard2009-09-198-27/+30
| | | | | | | | | | | | | | | | A lot of tests wait, sleep or use a timer for multiple seconds when that is not necessary.

* Make tracepoints.exp test more efficient by running as one giant script.Mark Wielaard2009-09-131-6/+20
| | | | | | | | | | | When there are lots of tracepoints in the kernel running a script for each one individually can take several minutes. So run them all in one giant script at the same time. Also increase timeout for the stap -l collection step since with an empty cache that might take more than the default 10 seconds. * testsuite/systemtap.base/tracepoints.exp: Increase default timeout. Collect all script fragments and run them as one.

* Fix overlapping statement probe error in warnings.stp.Mark Wielaard2009-08-291-1/+1
| | | | | | | | | | | | | Instead of generating a warning the current kernel.statement probe produced a warning on some 386 kernels that had optimized that particular line: semantic error: multiple addresses for fs/bio.c:282 (try fs/bio.c:278 or fs/bio.c:284) semantic error: no match while resolving probe point kernel.statement("bio_init@fs/bio.c+3") So do as told to just get the expected warnings for this probe. * testsuite/systemtap.base/warnings.stp (probea): Probe bio_init@fs/bio.c+5.

* PR10568: Ensure that aliases pull in their tapsetJosh Stone2009-08-274-0/+37
| | | | | | | | | | | When a probe alias is resolved in a tapset, the contents of that tapset should be included in the compiled script, just as we do for global variables and functions. * elaborate.cxx (alias_expansion_builder::build): When an alias is instantiated, add its stapfile to the session files. * testsuite/systemtap.base/tapset_includes.exp: New test. * testsuite/systemtap.base/tapset/*.stp: Testing tapsets for above.

* PR10537 process().function().label() should select multiple inlined instances.Mark Wielaard2009-08-202-24/+29
| | | | | | | | | | | | | | | | | | | | This is less useful than one would hope. gcc will often emit a label with a DW_AT_low_pc that is not really in the neighbourhood of where one would expect it when the label is inlined and gcc can proof the label isn't really used in the optimized code. dwflpp::iterate_over_labels will now really iterate recursively through the die, even for dies without a name (like lexical blocks). This means we should now always find the concrete inlined label instances that have a real DW_AT_low_pc and so we don't need the trick to use the line table to get at the actual address. * dwflpp.cxx (iterate_over_labels): Accept dies without a name. Don't handle labels without a name or without a lowpc attribute. * testsuite/systemtap.base/inlinedvars.c (m): Trick gcc into thinking label is always used. (call, call2): Activate. (main): Call call and call2. * testsuite/systemtap.base/inlinedvars.exp: New result_string. Test both unoptimized and optimized (inlined) builds.
