* PR10458. User actual breakpoint address for [ku]probe[ret].Mark Wielaard2009-07-313-2/+68
| | | | | | | | | | | | | | | | | | | | Setup the pt_regs REG_IP to the actual breakpoint address before entering a probe handler for [ku]probe[ret] (and restore it after returning). This helps getting symbol resolution and backtraces more correct and makes it more conform with other probe handlers like the iutrace and profile timers that also provide pt_regs (which untill now exhibited off-by-one errors while unwinding). * tapsets.cxx (dwarf_derived_probe_group::emit_module_decls): Setup REG_IP correctly before calling enter_kprobe_probe and enter_kretprobe_probe, and restore afterwards. (uprobe_derived_probe_group::emit_module_decls): Likewise for enter_uprobe_probe and enter_uretprobe_probe. (kprobe_derived_probe_group::emit_module_decls): Likewise for enter_kprobe2_probe and enter_kretprobe2_probe. * runtime/unwind/i386.h (arch_unw_init_frame_info): Initialize info->call_frame to zero. * runtime/unwind/x86_64.h (arch_unw_init_frame_info): Likewise.
* Relax the type-matching in the cmd_parse13 testJosh Stone2009-07-301-1/+1
| | | | | Dwarf probes are now printing their $target variables in -L, so we need to handle more than just stap types in the regular expression.

* Use a real session flag for -LJosh Stone2009-07-292-10/+14

* PR10427 Multiple tracepoints OK!Mark Wielaard2009-07-221-1/+3

* Use the query paradigm for resolving sdt probesJosh Stone2009-07-212-377/+384
| | | | | | | | | | | | | | | | There was a bad assumption in the probe_table initialization that the dwflpp->module would be immediately valid. We should not assume that dwflpp only has one module, or that any module is necessarily in focus. Instead, I've created an sdt_query class which will call an iterate_over_modules like the other dwarf probe types. For now this means just a single module, but it will also open the door to iterating over all linked libraries too, for example. * dwflpp.cxx (dwflpp::setup_user): don't "save mod!" anymore * tapsets.cxx (probe_table -> sdt_query): convert to a query-style class, and also take over the task of iterating over the probes. (dwarf_builder::build): leave the iteration to sdt_query

* PR10424: Consider each tracepoint header separatelyJosh Stone2009-07-205-52/+83
| | | | | | | | | | | | | | | | With the current monolithic tracepoint query module, a failure in any of the discovered tracepoint headers means that you can't use any of the others either. This patch creates a separate query module for each header so they can pass or fail independently. * buildrun.cxx (make_tracequery): take a single header name instead of globbing for everything we can find. * hash.cxx (find_tracequery_hash): name the header file we're hashing. * tapsets.cxx (tracepoint_query::handle_query_func): make sure we don't duplicate tracepoints found through different headers. (tracepoint_builder::get_tracequery_module): get a header's module (tracepoint_builder::init_dw): glob for all tracepoint headers, and feed all their modules into dwflpp.
* Make sure that non-existent files still affect hashingJosh Stone2009-07-201-6/+6
| | | | | | | The fact that a file _doesn't_ exist is significant, so adding such a file to a computed hash should still influence the output. * hash.cxx (hash::add_file): add bogus stat info for non-existent files
* Allow dwflpp to take a vector of module namesJosh Stone2009-07-202-21/+38
| | | | | | | | | This will be used to load tracepoint modules as a bunch of little query modules into a single dwflpp. * dwflpp.cxx (setup_user): take a vector instead of a single module (dwflpp::dwflpp): form a vector in the singular case, and add a variant that takes and passes through a vector of modules.
* Return hash module values directly as stringsJosh Stone2009-07-204-20/+19
