I am no arm guru but doing some research it appears the same to me. 
Digging a little further i discovered that this portion of code come 
from arch/arm/pistachio/v5/src/traps.spp

I also found that v.2.1 doesn't contain any clz instruction. So for a 
quick test I copied this file from the v 2.1 to the current version 
(2.1.1-patch.9). And well I got a nice amount of test to pass. :)

Of course I know this solution may have unfortunate side effects.

Also does this means support for gta01 arch is currently broken ?

And would a proper solution be to have some arch/arm/pistachio/v4 
directory ?


Anyway thank you (as always).
