Martin Povišer 7c6cc4c40b tests: Fix invocation of 'help -cells' 
There's no such thing as 'help -celltypes' and there probably never was.

CORRADI Quentin e7156c644d Standard compliance for tests/verilog/block_labels.ys 
genvar declaration cannot take an initial value when declared as a module_or_generate_item_declaration.
Correct this test so that it doesn't fail unexpectedly if Yosys aligns with the standard.

Dag Lem ad437c178d Handling of attributes for struct / union variables 
(* nowrshmsk *) on a struct / union variable now affects dynamic
bit slice assignments to members of the struct / union.

(* nowrshmsk *) can in some cases yield significant resource savings; the
combination of pipeline shifting and indexed writes is an example of this.

Constructs similar to the one below can benefit from (* nowrshmsk *), and
in addition it is no longer necessary to split out the shift assignments
on separate lines in order to avoid the error message "ERROR: incompatible
mix of lookahead and non-lookahead IDs in LHS expression."

    always_ff @(posedge clk) begin
        if (rotate) begin
            { v5, v4, v3, v2, v1, v0 } <= { v4, v3, v2, v1, v0, v5 };

            if (res) begin
                v0.bytes <= '0;
            end else if (w) begin
                v0.bytes[addr] <= data;
            end
        end
    end

Jannis Harder 985f4926b7 verilog: Fix const eval of unbased unsized constants 
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.

Jannis Harder fb1c2be76b verilog: Support void functions 
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.

Jannis Harder 390d1c583a verific: Fix enum_values support and signed attribute values 
This uses the same constant parsing for enum_values and for attributes
and extends it to handle signed values as those are used for enums that
implicitly use the int type.
