I had accidentally introduced an endianness issue when applying the hash to the type unit. Using support::ulittle64_t in the reinterpret_cast in addDwarfTypeUnitType fixes this issue. Original commit message: Debug Info: Type Units: Simplify type hashing using IR-provided unique names. What's good for LTO metadata size problems ought to be good for non-LTO debug info size too, so let's rely on the same uniqueness in both cases. If it's insufficient for non-LTO for whatever reason (since we now won't be uniquing CU-local types or any C types - but these are likely to not be the most significant contributors to type bloat) we should consider a frontend solution that'll help both LTO and non-LTO alike, rather than using DWARF-level DIE-hashing that only helps non-LTO debug info size. It's also much simpler this way and benefits C++ even more since we can deduplicate lexically separate definitions of the same C++ type since they have the same mangled name. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@198436 91177308-0d34-0410-b5e6-96231b3b80d8
