## This test checks that lldb uses the abbrev_offset from .debug_tu_index when
## reading TUs in the .debug_info section of a DWARF v5 DWP.
##
## The assembly here is, essentially, slightly hand-reduced output from
## `clang -gsplit-dwarf -gdwarf-5 -fdebug-types-section`, with a manually-added
## .debug_cu_index and a .debug_tu_index to create a DWP, and a twist: abbrevs
## from the TU are listed *AFTER* abbrevs from the CU so that they don't begin
## at offset 0.
