* remove unnecessary blank lineJeff Wang2020-02-171-2/+1
|
* add attributes for enumerated values in ilangJeff Wang2020-02-173-2/+76
| | | | | | - information also useful for strongly-typed enums (not implemented) - resolves enum values in ilang part of #1594 - still need to output enums to VCD (or better yet FST) files
* separate out enum_item/param implementation when they should be differentJeff Wang2020-02-171-7/+16
|
* fix bug introduced by not taking all of PeterCrozier's changes in 16ea4ea6Jeff Wang2020-01-171-4/+6
| | | | | | | | The if(str == node->str) is in fact necessary (otherwise causes generate for in Multiplier_2D in tests/simple/multiplier.v to fail with error message "Right hand side of 3rd expression of generate for-loop is not constant!"). Note: in PeterCrozier's implementation, the break only breaks out of the switch-case, not the outer for loop.

* partial rebase of PeterCrozier's enum work onto current masterJeff Wang2020-01-165-17/+207
| | | | | | | | | | | 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." https://github.com/PeterCrozier/yosys/commit/881833aa738e7404987646ea8076284e911fce3f

| | | | | | | | | | | | | | | | | | | | | 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.
