Hi Jonathan,

I followed your command sequence and noticed a bunch of files being
created. However when I tried to run babeltrace on these outputs I don't
see any of the functions that should have been called.  Including below the
search for symbols.

root@RocrLnx23:~/git/compute/out/ubuntu-18.04/18.04/bin# babeltrace
 --debug-info-full-path  ~/lttng-traces/  | *grep -i hsa*
[17:36:05.323641697] (+0.000000207) RocrLnx23 lttng_ust_statedump:bin_info:
{ cpu_id = 6 }, { baddr = 0x7F9A2D05E000, memsz = 2320072, path =
"/home/user1/git/compute/out/ubuntu-18.04/18.04/lib/*libhsakmt.so*.1.0.99999",
is_pic = 1, has_build_id = 1, has_debug_link = 0 }
[17:36:05.323644111] (+0.000000186) RocrLnx23 lttng_ust_statedump:bin_info:

is_pic = 1, has_build_id = 1, has_debug_link = 0 }
root@RocrLnx23:~/git/compute/out/ubuntu-18.04/18.04/bin#

Any suggestions. I did build my executable and shared libs using the
compiler codegen flag for functions.

Regards,
Ramesh
