Hello,
Our GCC port & VLIW target processor support predication. However, I don't
see the GCC schedule two mutually exclusive blocks (from IF and ELSE ) in
a way that they are independent from each other.
I am wondering if this is a problem of our porting and I missed some tricks
, or it is current limitation of GCC.
Thanks,
