<pre>Recent Phoronix article mentions huge compile time / perf regressions.
For example:
<a href="https://www.phoronix.com/scan.php?page=article&item=gcc-clang-3960x&num=4">https://www.phoronix.com/scan.php?page=article&item=gcc-clang-3960x&num=4</a>
ImageMagisk - 50 % worse compile time.
PHP - 20 % worse compile time.</pre>
