Hi,

I am using a C5510 EVM board and I find that the three stack
configurations - USE_RETA, NO_RETA and C54x_STK behave in the same manner;
i.e, RETA register is not being used and the return address is stored on the
stack for all the cases.

Another problem is with the aadd instruction, when it is used with SP.
For example, the instruction aadd #-5, SP should not modify the SSP for
configurations other than 32-bit stack configuration (C54_STK), but it
seems to be incrementing the SSP regardless of the stack configuration being
used.

I am using a Configuration file and setting the stack configuration in
Scheduling->HWI properties. Is there something I am missing?

thanks,
Padma.
