# done by loading r4 / r5 with the test_pattern and using store multiple
# instruction to store r4 / r5 to buf.  If explicit_bzero would be resolved in
# setup_explicit_clear, r4 / r5 would be stored to stack by _dl_runtime_resolve
# and the call to memmem in count_test_patterns will find a hit of the
