Merge pull request #1551 from whitequark/manual-cell-operands 
Clarify semantics of comb cells, in particular shifts
 2019-12-05 08:24:24 -08:00
whitequark e97e33d00d kernel: require \B_SIGNED=0 on $shl, $sshl, $shr, $sshr. 
Before this commit, these cells would accept any \B_SIGNED and in
case of \B_SIGNED=1, would still treat the \B input as unsigned.

Also fix the Verilog frontend to never emit such constructs.
