OpenMP Debugging Support (OMPD) - OpenMP Debugging Support (OMPD)

Available in AOCC 2.3 or later.

The AOCC installation includes OMPD for debugging C/C++ OpenMP programs through a gdb plugin with limited functionality.

Note: Debugging the code that runs on an offloading device is not supported.

Complete the following steps to use OMPD for debugging C/C++ OpenMP programs through a gdb plugin.

Note: For using the OMPD plugin, Python 3.5 or later is required.

Add folders ompd and lib to your LD_LIBRARY_PATH.

$ export LD_LIBRARY_PATH=<compdir>/aocc-compiler-<ver>/ompd:<compdir>/aocc-compiler-<ver>/lib:$LD_LIBRARY_PATH

Set OMP_DEBUG to enabled.
```
$ export OMP_DEBUG=enabled
```
Compile the program to be debugged with -g and -fopenmp options as follows for a sample C source file xyz.c.
```
$ <compdir>/aocc-compiler-<ver>/bin/clang -g -fopenmp xyz.c -o xyz.out
```
Note: The program to be debugged must have a dynamic link dependency on libomp.so under <compdir>/aocc-compiler-<ver>/lib for OpenMP-specific debugging to work correctly. You can check this using ldd on the generated binary, that is xyz.out.
Debug the binary xyz.out by invoking gdb with the plugin.
```
gdb -x <compdir>/aocc-compiler-<ver>/ompd/__init__.py ./xyz.out
```
Note: Use the <compdir>/aocc-compiler-<ver>/ompd/__init__.py plugin.
