Hello all, The 16bit target that i am porting to gcc4.1.2 doesn't have any instructions for 32bit operations. But for addition and subtraction there is addc subc instructions that consider carry bit also. Presently i have patterns for SImode addition and subtraction such that the template will have
add %0, %1\naddc %N0, %N1 sub %0, %1\nsubc %N0, %N1 Will it be possible for me to write separate patterns for the instructions add and addc? Regards, Shafi
