# We expect all loops should be unrolled by verilator,
# none of the loop variables should exist in the output:
for filename in test.glob_some(test.obj_dir + "/" + test.vm_prefix + "*.cpp"):
test.file_grep_not(filename, r'index_')
# Further, we expect that all logic within the loop should
# have been evaluated inside the compiler. So there should be
# no references to 'sum' in the .cpp.
