Bug 112697 – REGRESSION(r146164): It made all inspector tests timeout on ARM traditional with enabled DFG JIT

• Status: RESOLVED
• Resolution: DUPLICATE
• Component: JavaScriptCore

I'm bisecting the culprit.

[Csaba Osztrogonác]

It seems http://trac.webkit.org/changeset/146174 is the culprit or one of its
buildfix: http://trac.webkit.org/changeset/146178 or http://trac.webkit.org/changeset/146195

See r146178 results with applied the fix from r146195:
http://cute1.inf.u-szeged.hu:8010/builders/ARMv7%20Linux%20Qt5%20Release%20%28Test%29/builds/8093

[Csaba Osztrogonác]

The bug is valid with Thumb2 assembler too.

[Csaba Osztrogonác]

Oh no, thumb2 result can be invalid, because the fix from https://bugs.webkit.org/show_bug.cgi?id=103146 haven't been landed.

On r146178 + fix from r146195 + fix from bug103146, all inspector tests 
pass with Thumb2, so only ARM traditional is affected by this bug.

[Csaba Osztrogonác]

Not r146174 is the culprit, but http://trac.webkit.org/changeset/146164.

r146146 + r146195 (buildfix): http://build.webkit.sed.hu/builders/ARMv7%20Linux%20Qt5%20Release%20%28Test%29/builds/8096

[Csaba Osztrogonác]

I had to skip _all_ inspector test (r146275) to make the
ARM bot work again. (We can't wait for ~500x30 secs timeout)

[Csaba Osztrogonác]

inspector tests pass with disabled DFG JIT: http://build.webkit.sed.hu/builders/ARMv7%20Linux%20Qt5%20Release%20%28Test%29/builds/8209

So r146146 broke the ARM traditional with enabled DFG JIT only. :)

[Csaba Osztrogonác]

Fixed by https://trac.webkit.org/changeset/150748 and tests were unskipped by https://trac.webkit.org/changeset/150794
