AFAIR, Apple's tools only generate/support DWARF32. After implementing type-uniquing in dsymutil we didn't see any individual .dSYM bundles that came even close to the 4GB watermark. > > I'm looking at unifying LLDB's DWARF parser with LLVM's, and this is the > biggest functional difference I can see. > > Certainly we can improve LLVM's support for consuming DWARF64, but it's a > question of priorities.
