Jeff Wang 249876b614 support using previously declared types/localparams/params in package 
(parameters in systemverilog packages can't actually be overridden, so
allowing parameters in addition to localparams doesn't actually add any
new functionality, but it's useful to be able to use the parameter
keyword also)

Merge pull request #1759 from zeldin/constant_with_comment_redux 
refixed parsing of constant with comment between size and value
 2020-03-14 13:34:59 +02:00
Marcus Comstedt 5e94bf0291 refixed parsing of constant with comment between size and value 
The three parts of a based constant (size, base, digits) are now three
separate tokens, allowing the linear whitespace (including comments)
between them to be treated as normal inter-token whitespace.

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."

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.
