7# There's no other behavior to test hidden behind this error - lld only parses
8# the CU for the address ranges, it doesn't need to decode any strings.
9# LLD-NOT: error:

11## The code contains DWARF v5 sections .debug_rnglists and .debug_addr.
12## Check we are able to build the correct address
13## area using address range lists.

15# CHECK:      .gdb_index contents:
