| | | | | | | | * parse.cxx (parser::parse_symbol): Add sprint[ln] to @hist_* hack. * runtime/stat-common.c: Replace reprint with new reprint_buf, add more generic _stp_stat_print_histogram_buf and call it from the older one.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Inline functions do not have an indentifiable return point and require kernel built using VTA-enabled gcc to get tracking of variables. OTOH syscall functions are very rarely inlined (depending on the compiler mood), therefore filtering probes to include only non-inlined functions ensures consistent behavior between different kernels. This removes the problem of inaccessible variables in inlined syscalls that is described in comments #6-9 to PR5890 and gives us the status quo w.r.t. syscall probing, because before the commit solving PR10572 (b7478964) inline instances were masked anyway by non-inline ones. You can check whether you have inlined syscalls using following command: $ stap -l 'kernel.function("sys_*"),kernel.function("compat_sys_*")' \ 2>&1 -vvv | awk '/^selected inline/{print $5}' * tapset/syscalls.stp: Add .call to all entry probes. * tapset/syscalls2.stp: Ditto.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The problem in this bug is that our statement(NUM) lookup was only searching for the outermost function (not inlined) which contains the PC in question. When that PC happens to be the beginning of the function and also the beginning of an inline, the caching was using the wrong variable scope. The function/statement(NUM) lookup has been rewritten to bypass all of the CU and function iteration, and just go straight to a getscopes(pc) lookup, so it will now always use the innermost containing die for the variable scope. * tapsets.cxx (query_addr): New, short-circuit for numeric probes.

* Actually indent_thread() is a very useful function, butBreno Leitao2009-10-011-4/+16
| | | | | | | | | | | | | | | | | | | | | | sometimes you're probing something that is not related to any task, as an interrupt function, and if the application changes during the interrupt, the indentation gets confused. For example: 0 swapper(0): -> neo_copy_data_from_queue_to_uart 69 a.out(7659): -> neo_parse_modem 74 a.out(7659): -> neo_param 14 swapper(0): <- neo_copy_data_from_queue_to_uart 83 a.out(7659): -> jsm_carrier 86 a.out(7659): <- jsm_carrier 0 swapper(0): -> neo_parse_modem 94 a.out(7659): <- jsm_tty_set_termios 8 swapper(0): <- neo_parse_modem So, I decided to create a simpler function that doesn't consider the task. Much of the idea of this implementation came from Frank(Thanks)
