Hi gcc experts,

While updating the machine description file for our architecture ,we 
encountered the problem regarding conditional based transfer.
In gcc internals  specified that  conditional based transfer  can be 
supported using the standard pattern 'movModecc' as shown below.
                                 op0=(cc)? op2:op3
But our  architecture supports conditional transfer instruction as shown 
below:
           T<CC> op1, op2      It transfers the op1 to op2 if the <CC> 
is true otherwise it should behave like 'nop' .
 would u people tell me ,how to define the pattern in machine 
description file regarding the above specified issue.
