Marcelina Kościelnicka	8501342fc5	synth_xilinx: Use opt_dff. ... The main part is converting xilinx_dsp to recognize the new FF types created in opt_dff instead of trying to recognize the patterns on its own. The fsm call has been moved upwards because the passes cannot deal with $dffe/$sdff*, and other optimizations don't help it much anyway.	2020-07-30 22:26:09 +02:00
