Description Csaba Osztrogonác 2015-11-20 02:37:24 PST
New tests introduced in http://trac.webkit.org/r192664 fail on ARM Linux tester bots. 
Maybe they fail on iOS too, but I don't know, because there is no (public) iOS JSC tester.

I've confirmed the op_div failures on ARM64.  Checking ARMv7 now.
Comment 2 Mark Lam 2015-11-20 14:11:38 PST
I've also confirmed the op_rshift and op_urshift failures on ARMv7.
Comment 3 Mark Lam 2015-11-20 15:13:26 PST
I filed https://bugs.webkit.org/show_bug.cgi?id=151514 to track the ARM32 bugs, and https://bugs.webkit.org/show_bug.cgi?id=151515 to track the ARM64 bug.

I will skip those tests for now.
