# In earlier versions of isl, this test case would cause
# the loop coalescing avoidance to break down because one of the dimensions
# (Id2 in S_1) has a fixed value in terms of the other dimensions.
# Check that this no longer happens.
# The actual schedule that is produced is not that important,
# but it is different depending on whether the whole-component scheduler
# is being used, so pick a particular setting.
# OPTIONS: --schedule-whole-component
