Comment on attachment 532049 [details] [diff] [review] pixman-neon-fix-for-android.patch We're pretty sure this is a regression from Fx4 to Fx5 that will result in slower performance since we were not using NEON at all on Android.

Comment on attachment 532049 [details] [diff] [review] pixman-neon-fix-for-android.patch Please land this change on both Aurora and Beta. (In the future, getting changes in during Aurora will save you this extra step.)
Attachment #532049 - Flags: approval-mozilla-aurora+
Just to confirm something, is firefox5 mobile going to be released with or without this bug?
Unless it's landed on aurora and beta real soon now, without - but it's approved for beta (i.e. Fx5)!
I can land this in beta next week, if no gets to it first. (It's already on Aurora now because of the m-c to aurora merge.)
Target Milestone: --- → mozilla6
Oh man we dropped the ball not getting this into bate before beta 3 http://hg.mozilla.org/releases/mozilla-beta/rev/7b250e2b4f57 It's baked on trunk and aurora for a while with no ill effects. It's in beta now, headed to Fx5.
