# Check that we correctly track that GLOBAL_INV increases LOAD_cnt.
# We use a straightforward dependency between a GLOBAL_LOAD and an instruction
# that uses its result - the S_WAIT_LOADCNT introduced before the use should
# reflect the fact that there is a GLOBAL_INV between them.
# FIXME: We could get away with a S_WAIT_LOADCNT 1 here.
