# implicitly assumes that for each function every run line will

# generated functions as some run lines might not generate them
# (e.g. -fopenmp vs. no -fopenmp).
#
# Therefore, pass just the prefix we're interested in. This has
# the effect of generating all of the checks for functions of a
# single prefix before moving on to the next prefix. So checks
# are ordered by prefix instead of by function as in "normal"
