<pre>before r213645:
- <a href="https://build.webkit.org/builders/JSCOnly%20Linux%20AArch64%20Release/builds/4895">https://build.webkit.org/builders/JSCOnly%20Linux%20AArch64%20Release/builds/4895</a>
- runtime: 1h 15mins
- only 7 failures
after r213645:
- <a href="https://build.webkit.org/builders/JSCOnly%20Linux%20AArch64%20Release/builds/4950">https://build.webkit.org/builders/JSCOnly%20Linux%20AArch64%20Release/builds/4950</a>
- runtime: 10h 30 mins (stopped after it, full test runtime would have taken days)
- zillion timeouts
Note, that <a href="https://trac.webkit.org/changeset/213645">https://trac.webkit.org/changeset/213645</a> broke the build too
which was fixed in <a href="https://trac.webkit.org/changeset/213705">https://trac.webkit.org/changeset/213705</a>. But I tested
r213645 with the buildfix directly and it showed that r213645 caused this
serious regression.
Is there any way to disable this super slow new feature on Linux?
I don't and won't have to debug what caused this regeression in your patch.</pre>
