<pre>This is a meta bug for tracking work related to fixing all known failures from
debugify ( <a href="https://reviews.llvm.org/D40512">https://reviews.llvm.org/D40512</a> ).
The motivation for this is in order to provide the best possible user
experience when debugging optimized code by ensuring that optimization passes
preserve debug information wherever possible.

href="show_bug.cgi?id=37942#c1">Bug 37942, Comment 1</a>:
<span class="quote">> An error report from -check-debugify should always be considered a compiler
> bug. It would be cumbersome if we couldn't rely on this -- so much so that
> we should consider relaxing -check-debugify rather than allowing it to emit
> false positives.</span ></pre>
