However, it does work ok for ordinary code. * dwflpp.cxx (dwflpp::iterate_over_cus): Add 'want_types' argument. Iterate over type units. (dwflpp::declaration_resolve_other_cus): Update. (dwflpp::iterate_single_function): Update. (dwflpp::iterate_over_globals): Also allow DW_TAG_type_unit. * dwflpp.h (module_tus_read_t): New typedef. (dwflpp::iterate_over_cus): Update. (dwflpp::module_tus_read): New member. * tapsets.cxx (dwarf_query::query_module_dwarf): Update. (tracepoint_query::handle_query_module): Update. * testsuite/systemtap.pass1-4/debugtypes.cxx: New file. * testsuite/systemtap.pass1-4/debugtypes.exp: New file. * testsuite/systemtap.pass1-4/debugtypes.stp: New file. I built gdb with '-gdwarf-4 -fdebug-types-section'. Then I tried this stap script: probe process("/home/tromey/gnu/archer/build/gdb/gdb").function("dwarf2_attr") { println(@cast($dwarf2_per_objfile, "struct dwarf2_per_objfile")->objfile) } With Fedora 16 stap: barimba. stap -p2 /tmp/q.stp semantic error: type definition 'struct dwarf2_per_objfile' not found: identifier '@cast' at /tmp/q.stp:2:15 source: println(@cast($dwarf2_per_objfile, "struct dwarf2_per_objfile")->objfile) ^ Pass 2: analysis failed. Try again with another '--vp 01' option. After the patch, this works. ----------------------------------------------------------------------- Summary of changes: dwflpp.cxx | 31 +++++++++++++++++++++++---- dwflpp.h | 9 ++++++- tapsets.cxx | 4 +- testsuite/systemtap.pass1-4/debugtypes.cxx | 21 +++++++++++++++++++ testsuite/systemtap.pass1-4/debugtypes.exp | 16 ++++++++++++++ testsuite/systemtap.pass1-4/debugtypes.stp | 6 +++++ 6 files changed, 78 insertions(+), 9 deletions(-) create mode 100644 testsuite/systemtap.pass1-4/debugtypes.cxx create mode 100644 testsuite/systemtap.pass1-4/debugtypes.exp create mode 100755 testsuite/systemtap.pass1-4/debugtypes.stp hooks/post-receive -- systemtap: system-wide probe/trace tool
