Also, if you are familiar with binutils internals, it might be helpful<br>
to bisect the linker.<br>
<br>
Meador Inge has also mentioned this bug:<br>
<a href="https://llvm.org/bugs/show_bug.cgi?id=26580" rel="noreferrer" target="_blank">https://llvm.org/bugs/show_bug.cgi?id=26580</a><br>
<br>
Right now, it does not seem clear to me that we have an understanding<br>
what the issue is, which component is broken (LLVM, Swift's IRGen, or<br>
binutils), and if the breakage was accidental or intentional (e.g., to<br>
fix something else).<br>
