REGRESSION(FTL merge): There are still crashes on ARM

• Component: JavaScriptCore
• Status: RESOLVED INVALID

[Csaba Osztrogonác]

The status before the FTL merge: 0 crash on r153112
- http://build.webkit.sed.hu/results/ARMv7%20Linux%20Qt5%20Release%20%28Test%29/r153112%20%289096%29/results.html

Previous fixes landed in:
- https://trac.webkit.org/changeset/153612
- https://trac.webkit.org/changeset/153648

But unfortunately there are 7 crashes on ARM Thumb2:
- http://build.webkit.sed.hu/results/ARMv7%20Linux%20Qt5%20Release%20%28Test%29/r153643%20%289254%29/results.html

and 23 crashes on ARM Traditional:
- http://build.webkit.sed.hu/results/ARMv7%20Linux%20Qt5%20Release%20%28Test%29/r153645%20%289255%29/results.html

The test results show there was a crash, but there isn't a crash log.  Could you run one or more of these tests and attach a backtrace?

Unfortunately I can't do it on my summer holiday. 
Maybe rgabor could help you.

Gábor, any progression?

[Csaba Osztrogonác]

It seems there are still crashes on ARM traditional:
- http://build.webkit.sed.hu/builders/ARMv7%20Linux%20Qt5%20Release%20%28Test%29/builds/9707 - 27 crashing layout tests; LayoutTests/js tests: 9 failures found, 3 crashes found; Results for JSC stress tests: 28 failures found.

And a little bit less problem on ARM Thumb2:
- http://build.webkit.sed.hu/builders/ARMv7%20Linux%20Qt5%20Release%20%28Test%29/builds/9706 - 7 crashing layout tests; LayoutTests/js tests: 6 failures found; 
Results for JSC stress tests: 15 failures found.

I think it is invalid now, ARM are quite stable now.
