AMD developer teams do not have Valgrind supression file. However you can disable the false leaks by enabling environment, ENABLE_CAL_SHUTDOWN = 1.
Hope this helps.
It did not work for me under Linux. Also recently there are more problems and my suppression-file has grown. In my memory I did not see definite memory leaks before.
See StreamComputing | Valgrind suppression file for AMD64 on Linux for my suppression-file.
