Second off-loaded function not in DWARF #37
Description
Using a build with the commit #27.
The attached script sum_2.py has a kernel function 'data_parallel_sum', which calls another off-loaded function 'kernel_sum'.
GDB can set breakpoints in the function 'data_parallel_sum', but not in the function 'kernel_sum'.
To reproduce:
$ export NUMBA_DPPL_DEBUG=1
$ export NUMBA_SAVE_DPPL_IR_FILES=1
$ gdb-oneapi -q --args python sum_2.py
(gdb) break sum_2.py:13
(gdb) run
<GDB hits a breakpoint at line 16>
(gdb) backtrace
Expected results: GDB hits breakpoint at line 13. Command "backtrace" lists both functions "kernel_sum" and "data_parallel_sum".
Detected : GDB hits a breakpoint at line 16, which is not in the function "kernel_sum", but in the function "data_parallel_sum".
Further more, it is not possible to enter the function "data_parallel_sum" even by stepping.
Investigating the LLVM IR, we can see that the "data_parallel_sum" is not introduced in the debug data (at the end of the file llvm_kernel.ll).
Since it is not in the IR, it is also not in the IGC generated DWARF.
