* | PR10726: Get the correct scope for statement(NUM)Josh Stone2009-10-051-230/+217
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. (dwarf_query::query_module_dwarf): Route num probes to query_addr. (query_label): Assume now that we only need to handle _str probes. (query_dwarf_inline_instance): Ditto. (query_dwarf_func): Ditto. (query_cu): Ditto.

* | PR10678 vta-gcc: module debuginfo: relocation refers to undefined symbolMark Wielaard2009-10-022-1/+111
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | libdwfl tries to resolve all relocations in a module debuginfo file and if it cannot find a symbol used in a relocation it will fail when dwfl_module_getdwarf() is called. So we must make sure all possible dependencies of the module are also in the dwfl. We do this by trying to find and parse the modules.dep file and insert all dependencies into the dwfl. * setupdwfl.cxx (elfutils_kernel_path): Lift from setup_dwfl_kernel and make static. (is_comma_dash): New function. (modname_from_path): Likewise. (setup_mod_deps): Likewise. (setup_dwfl_report_kernel_p): Call setup_mod_deps(). * testsuite/buildok/pr10678.stp: New test.

* Print total memory usage in verbose mode after pass 1, 2 and 3.Mark Wielaard2009-10-011-6/+35
| | | | | | | Makes it easier to see which probe queries use lots of memory. * main.cxx (getmemusage): New function. (main): Use new function printing passes in verbose mode.
* 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)
