* Emit code to hook up tracepoint probesJosh Stone2009-03-061-4/+157
| | | | | | | | | | | | | | | | * tapsets.cxx (tracepoint_arg): New (tracepoint_derived_probe): Add declaring header name and arg vector (dwarf_type_name): Build a type string for a given type DIE (tracepoint_derived_probe::build_args): Scan the function DIE for the name and type of formal parameters required by the tracepoint. (tracepoint_derived_probe::tracepoint_derived_probe): Call build_args and determine the relevant header to include. (tracepoint_derived_probe_group::emit_module_decls): For each tracepoint, include its header and declare a probe entry point with the right function signature. (tracepoint_derived_probe_group::emit_module_init): Call the registration for each tracepoint, and handle error unwinding. (tracepoint_derived_probe_group::emit_module_exit): Unregister each.
* Build skeleton tracepoint probesJosh Stone2009-03-061-4/+79
| | | | | | * tapsets.cxx (tracepoint_derived_probe): Create a skeleton probe (tracepoint_derived_probe_group): Create a skeleton group (tracepoint_query::handle_query_func): build a probe
* Scan tracequery.ko for tracepointsJosh Stone2009-03-061-1/+79
| | | | | | | * tapsets.cxx (tracepoint_query): Iterate over the modules, CUs, and functions in tracequery.ko looking for our hijacked tracepoint declarations. (tracepoint_builder::build): Run a tracepoint_query
* Build tracequery to scan for tracepointsJosh Stone2009-03-064-0/+155
| | | | | | | | | | * session.h (systemtap_session): add tracepoint_derived_probes * buildrun.cxx (make_tracequery): New - builds a kernel module that hijacks the tracepoint declarations, so we can query debuginfo. * buildrun.h: declare above * tapsets.cxx (tracepoint_builder): New builder for tracepoint probes. For now it just handles the initialization to build the tracequery kernel module.
* Make iterate_over_functions work with base_querysJosh Stone2009-03-061-14/+17
| | | | | | | | | | * tapsets.cxx (dwflpp::iterate_over_functions): Change arg from void* to base_query*, and add explicit function-search parameters. (query_cu): update caller (query_dwarf_func): update callback signature (Note: instead of passing around callback functions, it might be nicer to use a virtual method in base_query...)
* Make session.module_cache init more consistentlyJosh Stone2009-03-041-7/+3
| | | | | | | | | We used to check & init module_cache in a few inconsistent places. Now it is always handled in dwflpp::setup_user/setup_kernel. * tapsets.cxx (dwflpp::setup_user): add module_cache check (dwarf_builder::build): remove module_cache check (dwarf_cast_expanding_visitor::visit_cast_op): ditto

* Fix typo in kernel version check 2.6.21 -> 2.6.11 in inet_sock.Mark Wielaard2009-03-041-2/+2
| | | | | * tapset/inet_sock.stp (inet_get_local_port): Fix kernel version check. (inet_get_ip_source): Likewise.
* stap autoconf test for kernel stack trace supportTim Moore2009-03-045-6/+29
| | | | | | | | | | * buildrun.cxx (compile_pass): Add autoconf line for stack trace test, which defines STAPCONF_KERNEL_STACKTRACE. * runtime/autoconf-save-stack-trace.c: New file. * runtime/stack.c : Use STAPCONF_KERNEL_STACKTRACE instead of tests for kernel configuration and versions. * runtime/stack-i386.c : ditto * runtime/stack-x86_64.c : ditto
* PR9919: Set last_stmt for array (scalar or statistical) assignments.Mark Wielaard2009-03-043-2/+56
| | | | * translate.cxx (visit_arrayindex): Update last_stmt.

* Search for a label instead of an address for .so static probes.Stan Cox2009-03-031-1/+4
| | | | * tapsets.cxx (dwflpp::build): Use .label for .so instead of .statement(N)
* This patch updates the itrace code to support the new utrace interface.Maynard Johnson2009-03-032-29/+118
| | | | | It also adds a private copy of access_process_vm to runtime/itrace.c since that function is not consistently exported by all distros.
* PR9875: Remove sduprobesWenji Huang2009-03-034-166/+31
| | | | | | | | | | | | Impact: cleanup Since sdt.h is in git tree, sduprobes is no longer needed. * Makefile.am: Remove sduprobes. * Makefile.in: Regenerated. * doc/Makefile.in: Ditto. * runtime/sduprobes.c: Removed. Signed-off-by: Wenji Huang <wenji.huang@oracle.com>

| | | | | | | | | | | | | | * tapset/inet_sock.stp: Remove includes. (inet_get_local_port): No embedded C, use @cast. (inet_get_ip_source): Likewise. (daddr_to_string): New function, still some embedded C used.
| * Remove unnecessary embedded C include.Mark Wielaard2009-02-271-4/+0

| * Skip generating empty struct globalWenji Huang2009-02-241-15/+17

| | * Add a testcase for gtod init/killJosh Stone2009-02-231-0/+29
| | | | | | | | | | | | | | | | | | This test simply checks that _gettimeofday_init and _gettimeofday_kill are pulled in when gettimeofday is used, and also that they are NOT pulled in when gettimeofday is not used.
| | * Add selective use of _stp_time_init/kill (PR9822)Josh Stone2009-02-234-50/+75
| | | | | | | | | | | | | | | | | | | | | | | | Our gettimeofday runtime has frequent wakeups to stay in sync with kernel time, but this is wasted effort if gettimeofday is not used in the script. This patch moves the calls to _stp_time_init and _stp_time_kill into begin and end/error probes, which only get pulled in if one of the gettimeofday variants is called.
