* | 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.

* Grapher support now also needs libglademm24-devel, version 2.6.7 or higher.Mark Wielaard2009-10-012-3/+3
| | | | | * configure.ac: Clarify fail/help string when gtkmm support wasn't found. * configure: Regenerated.
* Add DEBUG_UPROBES for sdt semaphores.Stan Cox2009-10-012-3/+22
| | | | | | * tapsets.cxx (uprobe_derived_probe_group::emit_module_decls): Add DEBUG_UPROBES for sdt semaphores * dtrace.in (main): Add -k option to keep around the temp files.
* 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)

* PR10678 module reloc refers to symbol in dwarf refer to kernel symbols.Mark Wielaard2009-09-301-12/+35
| | | | | | | | | | | | | | First part of a fix for PR10678. Always include the kernel in the dwfl. This doesn't seem to impact performance noticable, so for now enable always. * setupdwfl.cxx (setup_dwfl_done): New variable, used to clean up logic in setup_dwfl_report_kernel_p(). (setup_all_deps): New static bool to indicate we want all deps (just the kernel for now, other modules coming). (setup_dwfl_report_kernel_p): Use new variables, shortcut kernel inclusion.

* Add -Werror to tracequery buildJosh Stone2009-09-291-1/+1
| | | | | | | | The final module build uses -Werror, so tracequery should as well to catch problems as early as possible. Some ext4 errors have crept in again (PR10703). * buildrun.cxx (make_tracequery): Add -Werror to EXTRA_CFLAGS.
* tapset docs cleanupFrank Ch. Eigler2009-09-2913-88/+90

| | | | | | | | | | * setupdwfl.h: Introduce DwflPtr. * setupdwfl.cxx: Cache kernel_dwfl and user_dwfl. Keep track of last used module strings. Return cached versions if same query used. * dwflpp.h: Use DwflPtr instead of Dwfl*. * dwflpp.cxx: Use DwflPtr and don't dwfl_end(). * translate.cxx: Likewise. Run through dwfl_getmodules() with returned ptr offset.

* Simplify copy_file callsJosh Stone2009-09-285-66/+36
| | | | | | | | | | | | | | Every single copy_file call we had was converting strings to char*, printing the same error message, and optionally printing the same verbose string. Let's canonicalize that. * util.cxx (copy_file): Take string filenames, add a verbose flag, and consolidate the message printing. * cache.cxx (add_to_cache): Pass strings and remove message printing. (get_from_cache): Ditto. * main.cxx (main): Ditto. * tapsets.cxx (tracepoint_builder::get_tracequery_module): Ditto. (dwarf_cast_expanding_visitor::filter_special_modules): Ditto.
* Try to build tracequery for all headers at onceJosh Stone2009-09-285-30/+55
| | | | | | | | | | | | | | | | | | | | | | To mitigate PR10424, we switched to building a separate tracequery module for each tracepoint header, so a bad header wouldn't break all of the others. However, with recent kernels that leads to ~18 make commands, which adds up quickly in time. It's cached, so that's not too bad, but as a developer who rebuilds stap frequently, it gets annoying. If we're going to call 18 makes, it's worth it to start with one bigger make that covers all the headers at once (like we used to). If that one fails, we can still fall back to compiling individually. FWIW, the failing ext4.h header was only created in 2.6.31, and was fixed before 2.6.32, so the specific failure in PR10424 has a fairly small window. * buildrun.cxx (make_tracequery): Just take a single vector of headers. * hash.cxx (find_tracequery_hash): Deal with multiple headers. * tapsets.cxx (tracepoint_builder::get_tracequery_module): Ditto. (tracepoint_builder::init_dw): Attempt all system headers together, and if that fails, try again individually.

* cleanup: tweak "read-only <variable>" messageFrank Ch. Eigler2009-09-281-4/+4
| | | | | | * elaborate.cxx (semantic_pass_opt2): Use "never-assigned" instead of "read-only". (dead_stmtexpr_remover::visit_expr_statement): Ditto.
* Use dwlpp::setup_kernel for tracepoint modules.Mark Wielaard2009-09-283-6/+36
| | | | | | | | | | | Tracepoint modules ended up going through dwflpp::setup_user() because there was no setup_kernel that takes a list of module names. * dwflpp.h: Add kernel_p bool to constructor that takes a module list. Add setup_kernel() variant that takes a module list. * dwflpp.cxx: Likewise. * tapsets.cxx (tracepoint_builder::init_dw): Call dwflpp constructor indicating we expect kernel modules.
* Factor out duplicated code to setup kernel/module Dwfl from dwflpp/translate.Mark Wielaard2009-09-286-162/+232
