<pre>This is another case of lax libcall function signature matching.
It requires a target (eg, Linux not macOS) that has "bcmp" to trigger.
Should be fixed with:
<a href="https://reviews.llvm.org/rGca637014f148">https://reviews.llvm.org/rGca637014f148</a>
This required changing a big pile of x86 regression tests:
<a href="https://reviews.llvm.org/rG8721490d3859">https://reviews.llvm.org/rG8721490d3859</a>
...and the bug has probably been around for a long time without anyone
noticing, so I'm marking as fixed instead of requesting backporting to the 13.0
release branch.</pre>
