Hi i have now tested the pr484 fix a bit more..  I have attached a 
complementary patch for pr484 that returns zero for three more of the 
ASM interpreters entry. With these fixes in place Shark now passes 
test_gamma on ARM in combination with the ASM interpreter!

I think the ASM interpreter starts to become ready to be merged and 
reenabled with Icedtea6 head,
now when pr323 and pr484 are fixed for the ARM ASM interpreter.

Yes running the interpreter in combination with the JITs needs more testing.


Cheers and have a great day!
