* Merge pull request #3734 from jix/fix_unbased_unsized_constHEADmasterJannis Harder2023-04-243-1/+36
|\ | | | | verilog: Fix const eval of unbased unsized constants
| * verilog: Fix const eval of unbased unsized constantsJannis Harder2023-04-203-1/+36
| | | | | | | | | | | | | | | | | | | | | | | | | | | | When the verilog frontend perfomed constant evaluation of unbased unsized constants in a context-determined expression it did not properly extend them by repeating the bit value. This only affected constant evaluation and not constants that made it through unchanged to RTLIL. The latter case was already covered by tests and working before. This fixes the const-eval issue by checking the `is_unsized` flag in bitsAsConst and extending the value accordingly. The newly added test also tests the already working non-const-eval case to highlight that both cases should behave the same.

| * verilog: Support void functionsJannis Harder2023-03-203-1/+56
|/ | | | | | | The difference between void functions and tasks is that always_comb's implicit sensitivity list behaves as if functions were inlined, but ignores signals read only in tasks. This only matters for event based simulation, and for synthesis we can treat a void function like a task.
