The profile spends most of the time in d/k(), the profile shows a ton of: 'Bailout_Normal after mul on line 1 of http://www.kevs3d.co.uk/dev/canvasmark/scripts/k3d-min.js:1' http://people.mozilla.org/~bgirard/cleopatra/#report=05f203a18a599b1057dddbe23c638bc6a8db214b

This is on Android Glaxy Nexus with a nightly build.
OS: Mac OS X → Android
Hardware: x86 → ARM
I can reproduce this on OS X, 32-bit. These bailouts happen during test 7 and are caused by LFloor...

BenWa, thanks for reporting this! The problem is caused by Math.ceil inlining, I filed bug 1010747. We should test this again when that bug is fixed.
BenWa, thanks again for reporting! Do you still see slowdowns and bailout markers in your code, now that 1010747 has landed?

It's fixed. I still see about 50ish bailout while running canvasmark but it looks better.
