* Move the "pure" tag into the body of __is_user_regsJosh Stone2009-05-222-2/+4
| | | | | | The "/* pure */" tag has no effect unless it is within the embedded-C body of a function. In this instance, they were accidentally moved out during the syscall cleanups.
* Use embedded-C for empty functionsJosh Stone2009-05-223-12/+6
| | | | | | | | | | The functions asmlinkage() and fastcall() are used to help access syscall parameters on i686. All other archs don't need this, but they still define empty functions to shield the callers from arch details. However, stap issues warnings for empty script-level functions. This patch changes them to "%{ /* pure */ %}" so there's no complaint, and they will still get optimized away.

* Restore staprun's support for REAL_UID/GIDJosh Stone2009-05-221-1/+14
| | | | | This is needed for run-stap so that stapio and all child processes can run as the originally invoking user instead of root.

| * Fix gcc warning about Dwarf_Addr initialization.Mark Wielaard2009-05-211-1/+1
| | | | | | | | * translate.cxx (dump_unwindsyms): Initialize eh_frame to 0, not NULL.
| * PR10177: init/kill time in sleepy context onlyJosh Stone2009-05-205-44/+42
| | | | | | | | | | | | | | | | | | | | | | | | Previously, _stp_init_time and _stp_kill_time were being called from begin/end/error probes, which will run with preemption disabled. The BUG reported on RT kernels showed that cpufreq_unregister_notifier can end up sleeping, which violates our preemption block. This patch moves the init/kill into systemtap_module_init/exit, where it is safe to sleep. The code maintains a new predicate with the define STAP_NEED_GETTIMEOFDAY, so we don't still incur any timer overhead if it's not used.

| | | | | | | | | | | | | | * runtime/unwind.c (unwind): Call new unwind_frame() first with debug_frame data, then if that wasn't able to unwind again with eh_frame data. (unwind_frame): Adapted version of old unwind() function that takes a table, table length and whether it is an eh_frame table.
| * Pass and use ptrType and is_ehframe to unwind adjustStartLoc.Mark Wielaard2009-05-201-53/+66
| | | | | | | | | | | | | | * runtime/unwind.c (adjustStartLoc): Add ptrType and is_ehframe as arguments. Use these to adjust location when necessary. (DEBUG_UNWIND): Move block before adjustStartLoc. Pass false for is_ehframe throughout.

(cie_for_fde): Take unwind_data and is_ehframe as direct arguments. * runtime/unwind/unwind.h (cie_for_fde): New function declaration. * translate.cxx (get_unwind_data): Fetch and return both debug_frame and eh_frame tables.

| | | | | | | | | | | | | | | Rules: - Specify probe points for aliases starting from the alias declaration line and with one probe point per line. - Use K&R indent style -- probe alias/point/function opening brace goes to the line following the declaration, other opening braces are kept on the same line as the control statements. - Indent using tabs. - Surround operators with spaces. - Put spaces after commas. - Avoid trailing whitespaces.

| | | | | | | | | | | | | | | | | | | | | | | | The method query_cu_containing_global_address was only called by query_cu_containing_module_address, and the latter was just doing a simple argument transform. They are now merged into a single method, query_cu_containing_address. The function module_address_to_global is also merged here at its only call site.
