[ixp1200] compiler optimizations--instruction address problem

Hi, When i run my code in simulation debug mode on the workbench ,i have set it to display the instruction addresses and in the project settings i have set compiler options for optimization to none. Inspite of that there are two instruction where the instruction addresses does not show up and the simulator does not execute them.Is it because of the code or the project settings. The instructions are buf_handle = receive_packet(0, 5, &cur_pkt_len); //buf_data_ptr = (__declspec(sdram) long long *)(buffer_get_data_ptr(buf_handle)); buf_data_ptr = (__declspec(sdram) void *) (((unsigned int)buffer_get_data_ptr(buf_handle)) + 3); If anyone is aware of the solution,please let me know. Thanks, shweta
