        <pre>Users have reported that VS and windbg can't display locals with clang's debug
info, even with -O0. See <a href="https://llvm.org/pr41049">https://llvm.org/pr41049</a> and
<a href="https://llvm.org/pr41997#c6">https://llvm.org/pr41997#c6</a>.

To my knowledge, nobody has made any serious effort to support codeview for
AArch64. We can probably get a lot of the low-hanging fruit just by using
llvm-pdbutil to compare the symbol records that MSVC generates to what clang
generates.</pre>
