        <pre>The traditional archive symbol table format uses 32-bit offsets into the
archive.  This obviously breaks down when the offset to some member is >=4G.

GNU ar/ranlib detects the situation and switches to the "/SYM64/" format for
the archive symbol table, which is just the same format but with 64-bit
offsets.

llvm-ar silently writes an archive with a bogus archive symbol table when its
output file contains a member that starts at >=4G.

AFAICT lld and other tools do not grok the "/SYM64/" format in their inputs.</pre>
