[OpenMP] [OMPD] [5/6] Implementation of OMPD debugging library - libompd. gdb-plugin: A Plugin code to gdb to leverage libompd to provide debugging support.

[Vigneshbalu]

Summary

This is part of the review: https://reviews.llvm.org/D100181

This patch includes python based plugin code to gdb that enables gdb to support OpenMP specific debugging through OMPD.
Loading of this plugin causes a few new gdb commands to be added ("ompd icv", "ompd parallel", "ompd bt", etc). The invocation of these commands results in the OMPD APIs being invoked with the required arguments to provide the user the needed information.
The plugin code also includes basic wrapper implementations of the callback routines.
Other than these, a few unit tests are included to verify if the return codes of the OMPD APIs align with what is specified in the standard. (ompdAPITests.c)

Gentle reminder, as it is one of the last two patches to complete OMPD.

Gentle Ping.

The change looks good in general.
I tested basic usage of the ompd plugin, and it seems to work fine as expected.
I encountered python-related build issues on some of my test systems (e.g., Ubuntu 18.04) which I cannot resolve by installing required python packages, so I wonder if we need to make this (ompd test infrastructure) an optional feature for those who are interested.

I will try to fix it by skipping the plugin build, if the build system is incompatible.
Please give me some time, I will revert with details.

[Vigneshbalu]

Fixes the build failure because of python (pip).

Ubuntu and debian have its own patch on python pip which was causing failure.
Made changes in CMake to pick proper flag depend upon distributions and pip versions.
Tested the same on debian, ubuntu (wiht 9.01 and 21+ pip versions), centos and rhel.

Gentle Reminder

[dreachem]

This looks good to me. Is there a particular version of gdb that this plugin depends on? I didn't see that documented.

[Vigneshbalu]

Since, the gdb interface code is written in python. GDB that uses libompd should be built with python 3.5 or above.

This is captured in "gdb-plugin/README.txt" under "NOTES" Section.

[dreachem]

LGTM.

[jdoerfert]

This caused additional and undisclosed dependences to python packages, e.g. setuptools.
Please introduce a check + message for those and avoid build errors if they are missing.

[ye-luo]

See build issue https://github.com/llvm/llvm-project/issues/56569

[Vigneshbalu]

Removing python packages dependencies.

[dreachem]

LGTM.

Could you introduce this as cache variable? Something like

set(DISABLE_OMPD_GDB_PLUGIN OFF CACHE BOOL "<Some description>")

See also https://cmake.org/cmake/help/latest/command/set.html#set-cache-entry.

And perhaps we could choose the default based on the availability of Python 3 development files?

openmp/libompd/gdb-plugin/CMakeLists.txt

18

Isn't this the same as the Development component from the previous line? Down there I don't see direct usage of PythonLibs, only Python3_INCLUDE_DIRS and Python3_LIBRARIES from the previous line.

CMake documentation also says that this is deprecated in favor of Python3 that you're already using. So this line can likely simply be removed.

[kaz7]

Hi, I'm having following errors after this patch. I'm compiling llvm and runtimes for X86. Is Python3_INCLUDE_DIRS required for the debugging purpose? Thanks!

thanks for the comments.
I will make it as cache variable.
yes, we can disable when python is not available, with a warning.
Let me check with others and update.

openmp/libompd/gdb-plugin/CMakeLists.txt

thanks for the catch. It seems redundant.
Let me verify and remove it.

[Vigneshbalu]

python3 is required to build gdb-plugin code. It is used as an interface between gdb, libompd and openmp runtime (libomp).
please use configuration variable "DISABLE_OMPD_GDB_PLUGIN" to disable the plugin code.

I will see if we can disable by default when python is not available.

Thanks. It works fine if I install not only python3 but also python3-dev, but it worth to modify CMakefile to handle users who install only python3.

Also please use positive logic and LIBOMP* or OPENMP* prefix, for consistency with other options.

openmp/libompd/gdb-plugin/README.txt

+Instructions to use OpenMP specific debugging support for debugging C/C++ OpenMP programs through the gdb plugin are as follows:
+===============================================================================================================================
+
+    Include libompd.so directory to LD_LIBRARY_PATH
+        $ export LD_LIBRARY_PATH=<installed_dir/lib/> or <build dir/libompd/src/> :$LD_LIBRARY_PATH
+
+    Set OMP_DEBUG to enabled
+        $ export OMP_DEBUG=enabled
+
+    Compile the program to be debugged with '-g' and '-fopenmp' options as shown for a sample C source file xyz.c
+        $ clang -g -fopenmp xyz.c -o xyz.out
+
+    NOTE:
+        The program to be debugged needs to have a dynamic link dependency on 'libomp.so' for OpenMP-specific debugging to work correctly.
+        The user can check this using ldd on the generated binary i.e. xyz.out
+
+    Debug the binary xyz.out by invoking gdb with the plugin as shown below. Please note that plugin '<..>/ompd/__init__.py' should be used
+
+        $ gdb -x <build_dir/libompd/gdb-plugin/python-module/ompd/__init__.py> or <installed_dir/share/gdb/python/ompd/__init__.py> ./xyz.out
+
+        - The gdb command 'help ompd' lists the subcommands available for OpenMP-specific debugging.
+        - The command 'ompd init' needs to be run first to load the libompd.so available in the $LD_LIBRARY_PATH environment variable, and to initialize the OMPD library.
+        - The 'ompd init' command starts the program run, and the program stops at a temporary breakpoint at the OpenMP internal location ompd_dll_locations_valid().
+        - The user can 'continue' from the temporary breakpoint for further debugging.
+        - The user may place breakpoints at the OpenMP internal locations 'ompd_bp_thread_begin' and 'ompd_bp_thread_end' to catch the OpenMP thread begin and thread end events.
+        - Similarly, 'ompd_bp_task_begin' and 'ompd_bp_task_end' breakpoints may be used to catch the OpenMP task begin and task end events; 'ompd_bp_parallel_begin' and 'ompd_bp_parallel_end' to catch OpenMP parallel begin and parallel end events.
+
+    List of OMPD subcommands that can be used in GDB:
+        - ompd init     -- Finds and initializes the OMPD library; looks for the OMPD library libompd.so under $LD_LIBRARY_PATH, and if not found, under the directory in which the OMP library libomp.so is installed.
+        - ompd icvs     -- Displays the values of OpenMP Internal Control Variables.
+        - ompd parallel -- Displays the details of the current and enclosing parallel regions.
+        - ompd threads  -- Provides information on threads of the current context.
+        - ompd bt [off | on | on continued]       -- Sets the filtering mode for "bt" output on or off, or to trace worker threads back to master threads. When ‘ompd bt on’ is used, the subsequent ‘bt’ command filters out the OpenMP runtime frames to a large extent, displaying only the user application frames. When ‘ompd bt on continued’ is used, the subsequent ‘bt’ command shows the user application frames for the current thread, and continues to trace the thread parents, up to the master thread.
+        - ompd step     -- Executes "step" command into user application frames, skipping OpenMP runtime frames as much as possible.
+
+
+NOTES:
+      (1) Debugging code that runs on an offloading device is not supported yet.
+      (2) The OMPD plugin requires an environment with Python version 3.5 or above. The gdb that is used with the OMPD plugin also needs to be based on Python version 3.5 or above.
