[Mono-dev] On what platform|cpu-arch|mono-version does full AOT actually work?

Looks like you are right regarding the fact that I will be running  
into a lot of problems...

Going to sound like a broken record...but I did get latest from SVN...  
compiled everything for the iPhone ARM...Successfully started up Mono  
on the iPhone device...started to compile mscorlib (profile 1 as well  
as profile 2) in AOT mode.....BAM!...same assert as mentioned below  
triggered.

Since I am able to run Mono on the iPhone and I am performing the AOT  
compilation on the iPhone with its ARM processor I am bit surprised  
that it still doesn't work... the only thing I can think of is that  
there are a few files that are generated before compilation... e.g.  
cpu-arm.h and a few others in the arch folder..and that they are not  
correct on my side... if anyone have those files and are able to run  
on the ARM processor I would love to take a look at them to compare....
