Well, I am pretty aware of that errata, I was asking for some real data, not what your expectations are.

In short - what is the overhead from workaround for ARM errata 430973.

Because I can give some hard values for thumb2:

from only Qt, gtk, hildon-desktop, hildon-home and hildon-status-menu thumb2 compiled the reduction of code size is exactly 19MB. If you wish I can search on #maemo-ssu for how is memory consumption reduced (for several Qt/QML applications), but it varies between 2 and 6 %. And from my personal experience helium-moble-browser is much faster and less laggy when run on top of thumb2 compiled Qt.

Have in mind that I am not arguing whether it is better to have thumb2 (with errata workaround) or not, I am missing data to do the evaluation, thus my question.

@AapoRantalainen - if you feel this is totally OT, my apologies, I will start a new thread, just say it.
