| | | | | | | | | | | | | | | | | | | | | | | | In 2.6.32-rc7, there are two power.h tracepoints headers, and only the one in trace/events/ is valid. In general, we can expect that trace/events/ has newer headers, so we should search those first. * tapsets.cxx (tracepoint_builder::init_dw): Search /events/ first.

| * Use DW_AT_MIPS_linkage_name when available in vardie_from_symtable.Mark Wielaard2009-11-171-1/+8
| | | | | | | | | | | | | | | | If there is a DW_AT_MIPS_linkage_name it encodes the actual name of the variable as used in the symbol table. * dwflpp.cpp (vardie_from_symtable): Check whether there is a DW_AT_MIPS_linkage_name attribute and use its value if so.
| * Remove caching of emit_address for kernel modules and shared libraries.Mark Wielaard2009-11-171-4/+7
| | | | | | | | | | | | | | | | | | | | Caching of the address is only safe for kernel addresses that can never change. For kernel module or dynamic shared library addresses it isn't safe to cache the address since they can be unloaded, reloaded or mapped differently in separate executables. * dwflpp.cxx (emit_address): Remove static from addr definition for kernel and dynamic modules.
| * Explain "cheat" comment in sym.c (_stp_tf_mmap_cb).Mark Wielaard2009-11-171-0/+11
| | | | | | | | | | | | | | | | | | | | | | | | We are abusing the "first" section address here to indicate where the module (actually first segment) is loaded (which is why we are ignoring the offset). It would be good to redesign the stp_module/stp_section data structures to better align with the actual memory mappings we are interested in (especially the "section" naming is slightly confusing since what we really seem to mean are elf segments (which can contain multiple elf sections). * runtime/sym.c (_stp_tf_mmap_cb): Add cheat comment.

| * Define IRQF_ONESHOT for older kernels.Mark Wielaard2009-11-161-0/+3
| | | | | | | | | | | | | | IRQF_ONESHOT was only introduced in 2.6.32. It doesn't hurt defining it if it isn't already there. It will just never show up on older kernels. * tapset/aux_syscalls.stp: Define IRQF_ONESHOT if not already defined.

| * Accept relative user module paths for -d.Mark Wielaard2009-11-131-5/+13
| | | | | | | | | | | | | | | | | | | | | | | | When using relative (non-canonical) paths for user modules one would get a confusing WARNING: missing unwind/symbol data for module 'bin/test'. Also unless the path started with '/' the task_finder wouldn't start. By checking that the given file can be made absolute (canonicalized) both issues are resolved and the user module will be correctly identified at both translation and runtime. * main.cxx (main): case 'd' try canonicalize_file_name() the argument first to identify user modules.
