* | Ensure \A_SIGNED is never used with $shiftxXiretza2020-08-182-1/+9
| | | | | | | | | | It has no effect on the output ($shiftx doesn't perform any sign extension whatsoever), so an attempt to use it should be caught early.
* | Respect \A_SIGNED for $shiftXiretza2020-08-187-65/+61
| | | | | | | | | | | | This reflects the behaviour of $shr/$shl, which sign-extend their A operands to the size of their output, then do a logical shift (shift in 0-bits).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The main part is converting ice40_dsp to recognize the new FF types created in opt_dff instead of trying to recognize the mux 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.

Instead, tighten this up to OR of the following: - defined value of A is equal to defined value of B, and B is not undefined - A is undefined
