# FIXME: The verifier should probably be handled to verify the hash table
# itself - in which case this test would need to be updated to have a correct
# hash table (currently hand crafted with no attempt at correct allocation of
# hashes to buckets) - and probably to verify that the section ranges apply to
# sections that exist, which currently they don't
# This tests that an index that describes units as being in overlapping
# sections is invalid (this was observed in the wild due to overflow due to the
# 32 bit limit of the indexes (a DWARF spec bug - there should be a 64 bit
# version of the index format with 64 bit offsets/sizes)) - but Type Units will
# generally share all the sections other than the info section with each other
# (and with their originating CU) since the dwo format has no way to describe
# which part of non-info-section contributions are used by which units, so
# they're all shared. So demonstrate that the TU index ignores non-info overlap,
# but the CU index diagnoses such overlap (in the abbrev section, in this case)
# This doesn't currently check for info section overlap between the CU and TU
# index, but that could be an extension of this work in the future.
