Jesús Alberto López Soto 724a42e31d Fix reevaluation of method calls in wait conditions (#8391) 2026-09-18 15:41:01 -04:00
Geza Lore ccb4ab9fe3 Optimize Dfg vertex input edge storage (#8313) 
Store input edges of fixed arity vertices inline in the vertex class.
This reduces heap allocations, memory fragmentation, and pointer chasing
and speeds up Dfg passes. The extra branch introduced in inputEdgep() is
well predictable and profiling shows branchless alternatives are a loss.

Geza Lore 1c4c6c9e9d Improve V3Split (#8385) 
Various cleanups, simplifications and improvements:
- Build the output bottom up, eliminating AstSplitPlaceholder
- Replace the 'ignore step' pruning with removing the vertices and edges
- Treat an NBA written variable as a block input, enabling more splits
- Move instead of clone leaf statements

Overall V3Split is faster, uses less memory, can do more splits, is
simpler algorithmically, and has half the lines of code in V3Split

Most notably this can now be split, which could not be before:

```systemverilog
always @(posedge clk) begin
    a <= !a;
    if (a) b <= c;
end
```

t_x_rand_mt_stability* pin $random values, but there is one random seed
per C thread, so they depend on which thread runs the block. More
splitting moved that block onto a different thread, so force a single
MTask in those tests to keep them stable.

Some property/assert test changed hit counts due to races, but are now
closer to what might be expected.
