Jeff Wang 5ddf84d430 allow enum typedefs 2020-01-16 17:17:42 -05:00
Jeff Wang 16ea4ea61a partial rebase of PeterCrozier's enum work onto current master 
I tried to keep only the enum-related changes, and minimize the diff. (The
original commit also had a lot of work done to get typedefs working, but yosys
has diverged quite a bit since the 2018-03-09 commit, with a new typedef
implementation.) I did not include the import related changes either.

Original commit:
"Initial implementation of enum, typedef, import.  Still a WIP."

Rodrigo Alejandro Melo e9dc2759c4 Fixed some missing "verilog_" in documentation 2019-12-13 10:17:05 -03:00
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.

This is very useful to stop a synthesis of a parametrized block when an
illegal combination of parameters is chosen.
