Hi,

I've committed this patch which makes a small change to the generated 
code for accurate floating point ops. The change is to not dereference 
CGEN_CPU_FPU (current_cpu)->ops->XXXXX. This makes no difference for 
cgen simulators generated for  sim/common, but does allow the 
implementation of 'ops' to be a C++ class with virtual member functions 
for each operation for SID.

The SID patch which makes use of this will follow shortly.
