These are the new failures we saw on iOS AArch64 after r181993:

Comment 4 Csaba Osztrogonác 2015-04-14 07:52:59 PDT 
This bug is still valid.
Comment 5 Csaba Osztrogonác 2015-10-27 10:41:53 PDT 
I tested it again on ToT, stress/arguments-inlined-exit-strict-mode.js.default-ftl doesn't fail now ... but something is changed,
because FTL JIT isn't run at all for this test now.

Of course FTL runs for the "ftl-eager-no-cjit" case ... 
but this test always passed in the passed.

So the bug can be valid, but isn't triggered anymore.
Comment 6 Zan Dobersek 2017-10-18 01:41:43 PDT 
These failures aren't exhibited anymore.
