This updates includes moving onto elfutils-libdw and the lazy line matching support which you had mentioned :-) elfutils library is developed closely with gcc team, and it is simple and fast dwarf analysis library. lazy-matching is similar to glob matching but ignoring spaces in both of target and pattern. Changes in v3: - Cast Dwarf_Addr/Dwarf_Word to uintmax_t for printf-formats. - Recover a sign-prefix which was removed in v2 by mistake. Changes in v2: (Fixed bugs on x86-64) - Fix a type-casting bug in Makefile. - Cast Dwarf_Addr/Dwarf_Word to unsigned long long for printf-formats. This is updated todo list. Most of them are related to the 'type' support. Long-term TODOs (future features): - Enhance probe-finder to decode call frame instructions. - Support sys_perf_counter_open (for non-root users) - Support tracing static variables (non global) - Support variable types from debuginfo (e.g. char, int, ...) - Support fields of data structures (var->field) - Support array (var[N]) - Support dynamic array-indexing (var[var2]) - Support string/dynamic arrays (*var, var[N..M]) - Support force type-casting ((type)var) - Support the type of return value Miscs: - Better support for probes on modules - --list option shows the file-name/line-number of each events. - More debugger like enhancements(%next, --disasm, etc.) Thank you, --- Masami Hiramatsu (9): perf probe: Add lazy line matching support perf probe: show more lines after last line perf probe: Check function address range strictly in line finder perf probe: Use libdw callback routines perf probe: Use elfutils-libdw for analyzing debuginfo perf probe: Rename probe finder functions perf probe: Fix bugs in line range finder perf probe: Update perf probe document perf probe: Do not show --line option without dwarf support tools/perf/Documentation/perf-probe.txt | 58 ++ tools/perf/Makefile | 10 tools/perf/builtin-probe.c | 36 + tools/perf/util/probe-event.c | 55 +- tools/perf/util/probe-finder.c | 1002 ++++++++++++++----------------- tools/perf/util/probe-finder.h | 53 +- tools/perf/util/string.c | 55 +- tools/perf/util/string.h | 1 8 files changed, 644 insertions(+), 626 deletions(-) -- Masami Hiramatsu e-mail: mhiramat@redhat.com -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
